The free list-building popup tool that now ships under the name BDOW!

Sumo is a website lead capture tool that adds email opt-in popups, scroll boxes, welcome mats, smart bars, click triggers, inline forms, countdown timers, and social proof notifications to a site through a single script or a WordPress plugin. Launched as SumoMe in 2014 by the AppSumo team, it was acquired by website builder Showit in late 2023 and rebranded to BDOW! (pronounced buh-dow) in April 2024, operating today under Formilytics LLC at bdow.com while keeping a permanently free plan.

Overview

Sumo did more than almost any other product to make the email opt-in popup a default part of running a website. When SumoMe launched in 2014 it arrived as a free app store bolted onto any site: install one script, switch on List Builder, Welcome Mat, Smart Bar, Share, Heat Maps, and Image Sharer, and a blogger with no budget suddenly had the same list-building kit an agency would have charged for. The free tier was the whole strategy, and for several years Sumo was the most installed popup tool on the web.

The product's identity has changed twice since. In 2017 the company bought the sumo.com domain for a reported $1.5 million and dropped the Me. In December 2023 Showit, the drag-and-drop website builder popular with photographers and creative small businesses, acquired the tool from The Sumo Group, which kept AppSumo and KingSumo. A new entity, Formilytics LLC, was formed to run it, and in April 2024 the product was renamed BDOW!. Anyone searching for Sumo today lands on bdow.com; the sumo.com domain itself stayed with AppSumo and no longer serves the popup product.

What survives is a competent, narrow, honestly priced form builder aimed at the Showit and WordPress end of the market: creatives, bloggers, course sellers, and small ecommerce stores. The form types cover the standard catalogue, targeting is genuinely deep (URL, device, referrer, exit intent, cookies, query parameters, visitor behavior), A/B testing is one click, and paid plans add ecommerce features like discount codes, cart abandonment forms, and social proof popups. Recent additions include evergreen countdown timers that reset per visitor and a rebuilt interface.

The honest caveats are equally clear. The template library is small and users report that layouts, buttons, and mobile views resist customization. WordPress.org reviews over the past several years describe broken logins, plugin incompatibility, and slow support, though the plugin has been maintained through the rebrand and the script was reported roughly 35 percent faster after a performance pass. Development moves at the pace of a small team inside a website-builder company rather than a venture-funded conversion platform, so buyers comparing against OptinMonster or Klaviyo-native forms should expect fewer features and a considerably lower bill.

Best for

Bloggers, creators, course sellers, and small WordPress or Showit sites that want a capable opt-in popup and form tool with a real free plan and a flat, low, non-traffic-scaled price when they outgrow it.

Not the right fit for

Teams that need a large, modern template library or fine-grained design control; the templates are dated and users consistently report the layouts are hard to bend.
Ecommerce stores wanting personalized or AI-driven offers; every visitor in a segment sees the same manually configured form, with no product recommendation logic.
High-traffic sites, since paid plans meter 25,000 pageviews per site and the product is not positioned for volume.
Agencies managing many client sites; the top plan covers three sites, which is well short of a portfolio.
Anyone who needs fast, technical support, given the recurring pattern of slow or unresolved support reports in public reviews.
Buyers who require a mature, heavily invested roadmap; this is a small team inside a website-builder company, not a venture-funded conversion platform.

How it works

1
You create a free account at bdow.com and connect a site, either by pasting the JavaScript snippet into the site template, installing the WordPress plugin (still listed under the sumome slug), or enabling the native integration if the site is built on Showit or Shopify. The script loads asynchronously so it does not block page rendering.
2
Inside the dashboard you pick a form type: popup, scroll box, welcome mat (a full-screen takeover above the fold), smart bar (a sticky top or bottom strip), click trigger (a form opened by a link or button), inline embed, countdown timer, or social proof notification. Each starts from a template and is edited in a visual builder covering copy, colors, imagery, and fields.
3
Display rules decide who sees it. You can target or exclude by URL and page, device type, referrer, number of pages viewed, exit intent, cookies already set, and query string parameters, and you can control frequency so a returning visitor is not shown the same offer repeatedly. Exit intent, advanced targeting, and A/B testing sit behind the paid plans.
4
Captured addresses flow to your email tool through a direct integration (Kit, Flodesk, Mailchimp, Klaviyo, ActiveCampaign, MailerLite, AWeber, Constant Contact, HubSpot, Drip, Campaign Monitor, GetResponse and others), through Zapier, through webhooks on paid plans, or as a CSV export. Because addresses are stored in BDOW! as well, you can switch email providers without rebuilding forms.
5
Paid plans add a light email layer of their own: welcome emails, autoresponders for delivering content upgrades, and email broadcasts, metered per month (6,000 emails on Pro, 10,000 on Plus). Analytics report views, conversions, and conversion rate per form, with A/B test results and a two-year data window on paid plans.

Feature breakdown

28 features in 4 modules

Form types

The standard catalogue of on-site capture formats, all built in one dashboard.

Popups: The core modal opt-in, triggered by time on page, scroll depth, click, page count, or exit intent, with per-visitor frequency capping.
Welcome mat: A full-screen takeover that covers the page on arrival and pushes content down, the highest-conversion and highest-friction format in the set.
Smart bar: A slim sticky bar pinned to the top or bottom of the viewport for an offer or announcement that follows the reader without blocking anything.
Scroll box: A corner slide-in that appears at a chosen scroll percentage, the standard choice for long-form blog posts where a modal would feel aggressive.
Click trigger: A form that opens only when a specific link or button is clicked, which is how content upgrades are delivered without interrupting anyone.
Inline embed: A form placed in the flow of the page or in a sidebar via shortcode or embed, for the always-visible signup slot at the end of an article.
Evergreen countdown timers: A deadline that starts and resets per visitor rather than at a fixed date, so an offer stays urgent for someone arriving at any time.
Social proof popups: Small corner notifications showing recent signups or purchases, available on Pro and Plus and configured as a campaign rather than a form.

Targeting and testing

The rules that decide who sees a form, and the mechanism for proving one version beats another.

Exit intent: Fires when cursor movement suggests the visitor is about to leave the tab, reserved for paid plans and the most commonly cited reason to upgrade.
URL and page rules: Include or exclude specific pages, path patterns, or whole sections, so a checkout page and a blog post do not get the same offer.
Device targeting: Separate rules for desktop, tablet, and mobile, which matters because a welcome mat that works on desktop is often the wrong call on a phone.
Referrer and campaign targeting: Match on the referring domain or on query string parameters, letting a paid-traffic landing page show a different capture offer than organic search.
Behavioral and cookie rules: Trigger on pages viewed, time on site, or the presence of a cookie, which is also how you suppress the form for people who already subscribed.
Frequency and display control: Set how often a returning visitor sees a given form and how variations are distributed, so testing does not create a hostile experience.
One-click A/B testing: Duplicate a form, change the headline, fields, or messaging, control the traffic split, and promote the winner with a single click.

Ecommerce and monetization

The paid-plan layer aimed at WooCommerce and Shopify stores rather than blogs.

Discount code delivery: Issue a coupon in exchange for an email address, with the code shown in the form and passed through to the store.
Cart abandonment forms: Exit-intent capture on cart and checkout pages designed to recover a session before the visitor closes the tab.
Average order value prompts: Threshold-based offers such as free shipping above a spend level, shown while the cart is open rather than after the fact.
WooCommerce integration: Native connection to WooCommerce stores for order data and coupon handling, historically the deepest of the store integrations.
Revenue attribution: Reporting on revenue driven by BDOW! forms, so the subscription can be judged against the sales it actually influenced.

Email, data, and operations

Where the addresses go, and what the account administration looks like.

Direct ESP integrations: One-click connections to Kit, Flodesk, Mailchimp, Klaviyo, ActiveCampaign, MailerLite, AWeber, Constant Contact, HubSpot, Drip and around twenty others.
Welcome emails and autoresponders: Send the content upgrade or welcome message from BDOW! itself, useful for sites that have not yet chosen an email platform.
Email broadcasts: A basic one-off send to the collected list, metered at 500 emails per month free, 6,000 on Pro, and 10,000 on Plus.
Webhooks and Zapier: Paid plans can post submissions to an arbitrary endpoint, and Zapier covers the long tail of CRMs and spreadsheets without custom code.
Multi-site dashboard: Manage several properties from one login with user management controls, the feature the three-site Plus plan exists to serve.
Form analytics: Views, conversions, and conversion rate per form and per variation, with a two-year data retention window on paid plans.
Branding removal: The BDOW! badge on forms is present on the free plan and removed on paid plans, one of the two most common upgrade triggers alongside exit intent.
Asynchronous script loading: The tag loads without blocking render, and the team reported a script roughly 35 percent faster after a performance pass during the rebrand.

Use cases

5 documented

Food blogger monetizing an email list

Forty thousand monthly readers arrive from Pinterest and search, read one recipe, and leave with no relationship formed. There is no budget for a conversion platform.

A scroll box at 60 percent depth offering a printable meal-plan PDF, plus a click trigger on the recipe card itself, runs on the free plan and starts feeding Kit. The upgrade to Pro happens only once branding removal and exit intent become worth $19 a month.

Showit-based photography studio

A wedding photographer's site is built on Showit and converts inquiries through a contact form only, with no way to capture browsers who are not ready to enquire.

A welcome mat offering a pricing guide and a smart bar promoting a seasonal date is installed through the native Showit integration in an afternoon, with leads flowing straight into Flodesk and no developer involved.

Small WooCommerce store owner

Cart abandonment is high and the store has no dedicated onsite marketing tool, only the email platform's basic embed form.

An exit-intent form on the cart page offers a first-order discount code, a threshold prompt promotes free shipping above a spend level, and revenue attribution in BDOW! shows whether the $19 a month is earning its place.

Course creator running a launch

A cohort opens twice a year and the launch window depends on urgency, but visitors arrive across a three-week span rather than on one day.

An evergreen countdown timer starts on each visitor's first arrival rather than on a fixed date, paired with a click-triggered waitlist form, so the deadline stays real for late arrivals without faking a global one.

Designer maintaining three client sites

Three small business clients each need list building, and separate subscriptions per site would triple a bill nobody wants to justify.

The Plus plan covers all three sites from one dashboard at $39 a month billed annually, with per-site analytics and A/B tests, which lands well under three individual OptinMonster subscriptions.

Pricing

from Free forever; paid plans from $19 per month billed annually ($228 per year)

Flat monthly subscription by plan, with limits on number of sites, pageviews per site, and emails sent per month rather than on subscriber count. Annual billing is meaningfully cheaper than monthly. A permanently free plan exists and paid plans carry a 14-day free trial.

Plan	Price	Includes
Free	$0 per month	One site, 100 conversions, 500 emails per month Email opt-in forms, customizable design, social sharing Basic visitor targeting and analytics No exit intent, no A/B testing, and BDOW! branding stays on every form, which is exactly where the upgrade pressure sits.
Pro	$19 annually, $25 monthly per month (USD), $228 billed yearly	One site, 25,000 pageviews, 6,000 emails per month Branding removal, advanced visitor targeting, exit intent, and A/B tests Ecommerce features: discount codes, cart abandonment, average order value prompts, revenue reporting Welcome emails, email campaigns, webhooks, social proof popups, two-year analytics retention The plan almost every paying customer is on; the ecommerce layer is included rather than sold separately.
Plus	$39 annually, $49 monthly per month (USD), $468 billed yearly	Three sites, 25,000 pageviews per site, 10,000 emails per month Everything in Pro across all three properties from one dashboard User management controls for handing a site to a client or contractor Priced for a designer or small agency with a handful of properties, not for a portfolio.

Billing notes

There is no traffic-scaled subscriber tier ladder; the historic Sumo promise of one price regardless of list growth is broadly intact, with pageviews and emails as the meters instead.
Annual billing saves roughly 20 percent against monthly on both paid plans, $228 versus $300 on Pro and $468 versus $588 on Plus.
Paid plans are capped at 25,000 pageviews per site, which is the constraint most likely to bite a growing content site rather than the price.
Email sending is metered separately from capture, so a site using BDOW! broadcasts as its actual newsletter tool will hit the 6,000 or 10,000 monthly ceiling quickly.
The old Sumo tiers (Small, Medium, Big, Enterprise, running into four figures a year) are retired; anyone quoting those numbers is citing pre-2024 pricing.
A 14-day free trial and a 14-day money-back guarantee both apply, so the practical risk of trying a paid plan is close to zero.

Value assessment: On price per capability BDOW! is one of the better deals in lead capture: $19 a month buys exit intent, A/B testing, branding removal, webhooks, and a full ecommerce offer layer that OptinMonster and Privy gate behind higher tiers or usage bands. The catch is the ceiling. Twenty-five thousand pageviews per site, three sites at the top, a small template library, and no personalization mean the tool stops scaling well before the price becomes the problem. Judged as a cheap, flat-priced opt-in tool for a WordPress, Showit, or small WooCommerce site, it is good value; judged as a conversion platform, it is underpowered next to the current leaders.

Strengths & limitations

Strengths

A genuinely usable free plan with no time limit, which is why Sumo became the default popup tool for a generation of bloggers.
Flat pricing that does not escalate with subscriber count, unusual in a category where list growth normally raises the bill every year.
The full catalogue of form types (popup, welcome mat, smart bar, scroll box, click trigger, inline, countdown, social proof) in one dashboard rather than split across products.
Deep targeting rules for the price point, including cookie and query-parameter conditions that many cheaper tools omit.
One-click A/B testing with traffic split control and winner promotion, included on the $19 plan rather than sold as an upgrade.
Ecommerce monetization (discount codes, cart abandonment, average order value prompts, revenue attribution) bundled into the entry paid tier.
Around thirty direct email platform integrations plus webhooks and Zapier, with addresses stored in BDOW! so switching email tools does not mean rebuilding forms.
Native fit with Showit and a long-standing WordPress plugin, which makes installation a non-event for its core audience.

Limitations

A small, dated template library that reviewers repeatedly single out; layouts, buttons, and mobile views are hard to alter beyond the presets.
No personalization or product recommendation logic, so every visitor matching a rule sees the same manually configured offer.
Paid plans cap at 25,000 pageviews per site and three sites total, which rules out high-traffic publishers and agency portfolios.
Public WordPress.org reviews over several years report broken logins, incompatibility with current WordPress versions, and unresolved support tickets; the most recent reviews on that listing are poor.
Support is email-first through help@bdow.com with a documented pattern of slow replies, and there is no phone or guaranteed response time.
Two brand changes in seven years (SumoMe to Sumo to BDOW!) have fragmented the documentation, tutorials, and search results, and the sumo.com domain no longer serves the product at all.
The built-in email sending is a convenience layer, not a replacement for a real email platform: 6,000 to 10,000 sends a month with minimal automation.
Development velocity is that of a small team inside a website-builder company; several third-party reviews characterize the product as being maintained rather than actively expanded.

Head-to-head comparisons

7 alternatives

Sumo vs OptinMonster

from $7 per month billed annually ($84 for the first year, then $210 per year at list price)

OptinMonster is the more capable product and the more expensive one: a larger and better-maintained template library, richer campaign types, page-level targeting, and a roadmap that keeps moving. Sumo answers on price and simplicity, with a free plan OptinMonster does not offer and a flat $19 tier that includes exit intent, A/B testing, and ecommerce features. If design control and depth matter, pay for OptinMonster; if the job is a clean opt-in on a blog or a small store, Sumo does it for less.

Full Sumo vs OptinMonster comparison

Sumo vs Privy

from $24 per month for the Pop Ups and Displays plan (10,000 monthly pageviews); $30 per month for the Email plan (up to 1,500 contacts)

Privy is built for Shopify first and bundles email and SMS sending as a genuine channel, not a convenience layer. Sumo is platform-agnostic with a stronger WordPress and Showit story, and its ecommerce features (discount codes, cart abandonment, order value prompts) come in at $19 rather than climbing with contact count. A Shopify store planning to run its whole email program in one tool should look at Privy; a WooCommerce or content site that only needs capture is better served by Sumo.

Full Sumo vs Privy comparison

Sumo vs Poptin

from Free forever for 1,000 monthly visitors on one domain; paid Poptins plans from $25 per month billed annually

The closest match on price and posture. Both have real free plans and both sell a flat, low-cost paid tier with exit intent and A/B testing. Poptin's editor and template selection are more modern and its free plan is more generous on visitor volume, while Sumo counters with the countdown and social proof formats, the ecommerce monetization layer, and the Showit and WooCommerce integrations. For a straightforward popup on a budget, Poptin is usually the fresher choice.

Full Sumo vs Poptin comparison

Sumo vs Wisepops

from About $49 per month for 50,000 pageviews via the Shopify App Store; direct plans from about 499 euros per month, quoted only after a demo

Different buyers. Wisepops sells design quality, onsite messaging beyond opt-in, and behavioral personalization to marketing teams at established brands, priced accordingly and with no free plan. Sumo sells a cheap, flat-priced capture tool to creators and small stores. A team that cares about how the popup looks and about segmenting the offer will find Sumo's templates and rule engine limiting; a team optimizing for cost will find Wisepops hard to justify.

Full Sumo vs Wisepops comparison

Sumo vs Sleeknote

from From EUR 49 per month billed annually (EUR 62 monthly) for Core up to 25,000 monthly sessions; roughly USD 69 per month on the US price list

Sleeknote pushes non-intrusive, on-brand onsite messaging with heavy design polish and ecommerce guidance, at a price several times Sumo's. The gap is exactly the one Sumo's reviews identify: template quality and design control. Choose Sleeknote when the popup has to look like part of the site and the budget supports it; choose Sumo when the requirement is a working form with sensible targeting at the lowest defensible cost.

Full Sumo vs Sleeknote comparison

Sumo vs Claspo

from Free (about 3,000 pageviews per month); paid Pro plans from roughly $29 per month

Both lead with a permanent free plan, but they gate different things. Sumo's free tier is generous on traffic and thin on features, while Claspo caps the free plan at roughly 3,000 monthly pageviews and hands over the entire product: A/B testing, the full targeting engine, and eight gamified formats Sumo does not offer at any price. A low-traffic store running promotions gets more out of Claspo's free plan; a busier site that only needs a plain email form stays cheaper on Sumo.

Full Sumo vs Claspo comparison

Sumo vs Hello Bar

from Free (about 5,000 lifetime popup views); paid plans from $29 per month

The nearest peer in age and ambition, since both began as free one-click list-building widgets for bloggers and both now sell a low flat paid tier. The meters differ in a way that decides it: Hello Bar's free plan is capped at roughly 5,000 popup views in total rather than per month, and its paid plans start at $29 against Sumo's $19. Hello Bar earns the premium if you want the top-of-page notification bar it invented or the browser push companion; for a plain email form that runs for years, Sumo is the cheaper home.

Implementation & onboarding

Setup time: Under an hour. Create a free account, install the WordPress plugin or paste the script into the site template (or enable the native Showit or Shopify connection), pick a template, set display rules, and connect an email provider. A first live form in fifteen minutes is realistic.
Learning curve: Low. The builder is conventional and the display rules read in plain language. The part that takes longest is not the tool but the discipline of testing one variable at a time and matching each offer to the page it appears on.
Onboarding: Fully self-serve. There is a help center at help.bdow.com with setup guides and articles, a two-minute demo video, and a long-running content blog that predates the rebrand. There is no assisted onboarding tier.
Migration notes: Moving in is easy because there is little to migrate: rebuild the forms and repoint the ESP integration. Moving out means exporting the collected list as CSV and, importantly, removing the script. Several public reviews describe forms persisting after a plugin uninstall, so verify the tag is gone from the template and from any caching layer. Anyone on a legacy Sumo account should also confirm which entity holds their subscription, since the product moved from The Sumo Group to Formilytics LLC in the 2023 acquisition.

Platform, API & security

Platforms: Web (JavaScript snippet)WordPress pluginShowitShopifyWooCommerceGoogle Tag Manager
API: No documented public REST API for building on the platform. Integration is handled through around thirty direct email service provider connections, outbound webhooks on paid plans, Zapier, and CSV export.
Compliance: GDPR
Data residency: Not published; the operating entity, Formilytics LLC, is US-based.
SSO: Not offered; access is by email and password with user management controls on the multi-site plan.
Security notes: The tag loads asynchronously to limit render blocking, and the vendor states GDPR compliance for consent-based capture. Formal audit certifications such as SOC 2 are not published, which is a reasonable reflection of the segment this tool serves rather than an anomaly.

Support & resources

Channels: Email support (help@bdow.com)Help center and setup guidesIn-app help widget
Documentation: A help center covering campaign setup, targeting, integrations, and the WordPress plugin, plus a large archive of conversion and list-building articles carried over from the Sumo era. Some older articles still reference the previous brand names.
Community: No official forum. The WordPress.org plugin support threads are the closest public venue, and the Showit user community is an active informal channel for the creative small businesses that make up much of the current customer base.

Frequently asked questions

12 questions

Is Sumo still around, and why does sumo.com not show the popup tool?

The tool is still running, but under a different name and domain. Showit acquired Sumo from The Sumo Group in December 2023 and renamed it BDOW! in April 2024. It lives at bdow.com and is operated by Formilytics LLC. The sumo.com domain stayed with The Sumo Group, the company behind AppSumo, so it no longer serves the popup product.

Is Sumo free?

Yes, there is a permanent free plan: one site, 100 conversions, 500 emails a month, opt-in forms, customizable design, social sharing, basic targeting, and analytics. What the free plan does not include is exit intent, A/B testing, and branding removal, which are the three things that push most people to the $19 a month Pro plan.

How much does Sumo cost now?

Pro is $19 a month billed annually ($228 a year) or $25 a month billed monthly, covering one site, 25,000 pageviews, and 6,000 emails a month. Plus is $39 a month billed annually ($468 a year) or $49 monthly, covering three sites and 10,000 emails. Both carry a 14-day free trial. The old Sumo tiers running into four figures a year are retired.

What happened to the old Sumo apps like Heat Maps and Image Sharer?

The original SumoMe app store bundled several tools beyond opt-ins, including heat maps, content analytics, and an image sharer. The current product is focused on forms, popups, and social proof, with analytics limited to form performance. If you need behavioral heatmaps, that is now a separate purchase from a dedicated tool.

Does Sumo slow down a website?

The script loads asynchronously so it should not block rendering, and the team reported roughly a 35 percent speed improvement to it around the rebrand. That said, it is still a third-party script, and older public reviews from the pre-acquisition era complained about page speed. On a site where Core Web Vitals matter, measure with and without the tag before committing, and avoid running two popup scripts at once.

Does Sumo do A/B testing?

Yes, on paid plans. You duplicate a form, change the headline, fields, or messaging, control how traffic is split between variations, and promote the winner with one click. It is a genuinely simple implementation, and including it at the $19 tier is one of the product's better arguments against more expensive rivals.

Which email tools does Sumo connect to?

Around thirty direct integrations including Kit, Flodesk, Mailchimp, Klaviyo, ActiveCampaign, MailerLite, AWeber, Constant Contact, HubSpot, Drip, Campaign Monitor, and GetResponse, plus Zapier and outbound webhooks on paid plans. Addresses are also stored in BDOW! and exportable as CSV, so changing email platforms does not mean rebuilding your forms.

Sumo or OptinMonster: which is better for a small site?

OptinMonster has the better templates, more campaign types, and faster development, and it charges for it with no free plan. Sumo is cheaper and simpler, with exit intent, A/B testing, and ecommerce offers all included at $19 a month. For a blog or a small store that needs a working opt-in rather than a conversion program, Sumo is the more sensible spend; for design-led campaigns and depth, OptinMonster wins.

Can I use Sumo for a WooCommerce or Shopify store?

Yes. Paid plans include discount code delivery, exit-intent cart abandonment forms, average order value prompts, and revenue attribution, with a native WooCommerce integration and a Shopify connection. It is a capable basic store toolkit, but it does no personalization or product recommendation, so every matching visitor sees the same manually built offer.

How many websites can one Sumo account cover?

One site on the Free and Pro plans, and three on Plus, each capped at 25,000 pageviews a month on paid plans. There is a multi-site dashboard with user management, but three properties is the ceiling, which makes it unsuitable for an agency running a client portfolio.

Is Sumo GDPR compliant?

The vendor states GDPR compliance and the tool is designed for consent-based email capture, with the usual controls over when and to whom a form appears. Formal audit certifications such as SOC 2 are not published. As with any processor, the controller obligations, your privacy notice, your consent language, and your record of consent, remain yours.

What do users complain about most?

Three things recur across public reviews: a small and dated template library that resists customization, slow or unresolved email support, and, on the WordPress plugin listing, reports of broken logins and version incompatibility, including difficulty removing a form after uninstalling. Weigh those against a free plan and a low flat price before committing to an annual term.

Editorial verdict

Sumo's history is more interesting than its present. It normalized the free email capture popup, made list building a default habit for a generation of bloggers, and then changed hands and names twice, arriving as BDOW! under the website builder Showit. What is left is a decent, cheap, honest tool: every form type in one dashboard, targeting rules deeper than the price suggests, one-click A/B testing and an ecommerce offer layer both included at $19 a month, and a free plan that still does real work. What is also left is a small template library that reviewers keep flagging, a 25,000 pageview per site ceiling, a three-site maximum, and a support reputation that has not recovered. Buy it if you are a creator, a WordPress or Showit site, or a small store that wants capture working this afternoon for close to nothing. Look at OptinMonster, Poptin, or a Klaviyo-native form if design control, scale, or responsive support is the thing you cannot compromise on.
