The most generous free tier in email marketing, from a bootstrapped Lithuanian team

Sender is a marketing email and newsletter platform for campaigns and automated flows sent to a subscriber list, priced on subscriber count with a monthly send allowance of twelve to twenty-four times list size, notable for a permanent free tier covering 2,500 subscribers and 15,000 emails a month; it also includes a transactional email API and SMTP on every plan, which is unusual for a budget marketing platform.

Overview

Sender was founded in 2012 in Vilnius, Lithuania and has never taken outside money. It runs with a team of around thirty people, serves somewhere north of 180,000 businesses, and reached roughly $10M in annual recurring revenue while bootstrapped. It competes on a single, very effective proposition: give away more than anyone else and charge very little for the rest.

The free tier is the product's whole marketing strategy and it is genuinely aggressive. Two and a half thousand subscribers and 15,000 emails a month, with automation workflows, ten landing pages, popups and forms, responsive templates, and transactional email access all included. For comparison, MailerLite's free tier stops at 1,000 subscribers and 12,000 emails, AWeber's at 500 and 3,000, and Constant Contact has no free tier at all. What you give up on Sender's free plan is SMS, branding removal, A/B testing, and the advanced reports.

The paid plans start at $7 a month for Standard and $14 for Professional, with a 30 percent annual discount for first-time buyers. Standard adds three seats, branding removal, SMS, unlimited templates, A/B testing, and advanced ecommerce reporting, with a send allowance of twelve times your subscriber count. Professional adds ten seats, included SMS credits, advanced automation, per-group and per-inbox-provider reporting, priority support, and access to dedicated IPs, with a twenty-four times allowance. Enterprise adds unlimited sending, SSO with SAML, activity logs, an SLA, and phone support.

Two things a buyer should know before committing. First, Sender's price scales with subscriber count on a slider rather than in a published static table, so the $7 and $14 figures are entry points, not the price for a large list; read the slider for your own number before budgeting. Second, this is a very small company. Thirty people supporting 180,000 accounts is a lean ratio, and while the bootstrapped independence is a genuine stability argument, the depth of the product and the depth of the support organisation are both smaller than the incumbents' by a wide margin.

Best for

Price-sensitive small businesses, ecommerce stores, and solo operators who want a complete marketing email platform with automation and SMS for single-digit monthly spend, and anyone whose list is under 2,500 subscribers and would rather not pay at all.

Not the right fit for

  • Businesses that need deep marketing automation; the flow builder is competent but well short of ActiveCampaign, Klaviyo, or Omnisend on conditional logic and ecommerce personalisation.
  • Buyers who need a large support organisation; roughly thirty employees serving over 180,000 accounts means support is a queue, not a phone line, and there is no local partner network to fall back on.
  • Anyone whose main purchase is transactional email infrastructure; Sender's transactional feature is a convenience attached to a marketing platform, not a substitute for Postmark, Resend, Mailgun, or Amazon SES with their logging, inbound handling, and deliverability tooling.
  • Cold outreach and purchased-list senders; Sender requires permission-based lists and will suspend accounts whose complaint rates rise, as any shared-IP platform must.
  • Organisations that need events, ticketing, webinars, courses, or a CRM in the same account; Sender is an email and SMS platform and does not attempt any of that.

How it works

  1. 1

    You collect subscribers with Sender's forms, popups, and landing pages, or import a list, and organise them into groups with custom fields. Segments are built from behaviour, preferences, and purchase history on top of that.

  2. 2

    Campaigns are composed in a drag-and-drop builder with a responsive template library, then sent to a group or segment, scheduled, or A/B tested on the paid tiers. Sender's editor is deliberately conventional; there is nothing to learn that you did not already know from another platform.

  3. 3

    Automation flows are triggered by subscriber actions, purchases, or custom events you define, and can combine email and SMS steps in a single sequence. This is the feature that most distinguishes Sender from the other budget platforms, which usually cap automation on free plans or omit SMS entirely.

  4. 4

    Transactional email is available on every plan, including free, through a REST API or SMTP with SPF, DKIM, and DMARC authentication. It shares the account but not the campaign machinery, so receipts and password resets can be sent from the same vendor as the newsletter.

  5. 5

    Reporting covers opens, clicks, conversions, and ecommerce revenue per campaign and per automation, with the more granular views (performance by group and by inbox provider) reserved for the Professional tier.

Feature breakdown

26 features in 5 modules

Email campaigns

Conventional and complete, with the usual things not held back for a higher tier.
Drag-and-drop builder
Block-based composer with responsive templates, mobile preview, and an HTML option, available on every plan including free.
Responsive template library
A prebuilt library on all plans, with unlimited custom templates unlocked on Standard and above.
A/B testing
Test subject lines, send times, and content with automatic winner selection, available from the Standard tier.
Personalisation and dynamic content
Merge subscriber fields into subject lines and body copy, and vary blocks by group membership or purchase history.
Scheduling
Send immediately or schedule campaigns ahead, with send allowances of twelve times subscribers on Standard and twenty-four times on Professional.
Branding removal
Sender's footer branding is removed from the Standard tier upward; the free plan carries it.

Automation and SMS

Where Sender is unusually generous for the price.
Automation workflows
Trigger-based flows started by subscriber actions, purchases, or custom events you define, with waits and conditions. Available on the free plan, which most competitors do not do.
Multi-channel flows
Email and SMS steps can be combined inside a single automation sequence rather than run as parallel campaigns.
SMS marketing
Text campaigns available from the Standard tier, with included SMS credits on Professional.
Advanced automation
Deeper conditional flows are reserved for the Professional tier, along with priority support and richer reporting.
Abandoned cart and post-purchase flows
Ecommerce triggers from a connected store drive cart recovery and follow-up sequences.
Behavioural segmentation
Segments built from behaviour, preferences, and purchase history rather than list membership alone.

Audience acquisition

Included rather than upsold.
Popups and embedded forms
Exit-intent, timed, and scroll popups plus inline forms, writing directly into a subscriber group, available on the free plan.
Landing pages
A drag-and-drop page builder with ten pages included on the free plan, which is unusually generous for a free tier.
Ecommerce integrations
Connections to the main store platforms that sync products, orders, and customers for revenue reporting and cart recovery.
Custom fields and groups
Arbitrary subscriber attributes collected at signup or synced from a store, used for personalisation and segmentation.

Transactional email

A real API attached to a marketing platform, on every plan.
REST API and SMTP
Send application email such as receipts, password resets, and notifications through an API or SMTP relay, included on all plans including free.
Authentication support
SPF, DKIM, and DMARC configuration for the sending domain so transactional mail authenticates properly.
Separate from campaign sending
Transactional messages are handled outside the campaign machinery, though buyers should not mistake this for the stream separation Postmark builds its whole product around.
Pay-as-you-go credits
Prepaid email credits from $29 for 5,000 emails, roughly $5.80 per 1,000, for occasional senders who do not want a subscription.

Reporting and administration

Tiered, with the interesting views on Professional.
Campaign and automation analytics
Real-time opens, clicks, conversions, and ecommerce revenue attributed per campaign and per automation.
Performance by group and inbox provider
Professional adds reporting broken down by subscriber group and by receiving mailbox provider, which is how you spot a Gmail-specific deliverability problem.
Team seats
Three seats on Standard, ten on Professional, and configurable permissions on Enterprise.
Dedicated IPs
Available on the Professional tier, which is notably lower down the ladder than most competitors gate them.
SSO and activity logs
SAML v2 single sign-on, advanced permissions, activity logs, and an SLA on the Enterprise tier.
Priority and phone support
Priority support from Professional and phone support on Enterprise; the free and Standard tiers are ticket-based.

Use cases

4 documented

Solo operator with a 2,000-person list

A monthly newsletter and a welcome sequence, with no budget at all and no intention of paying for email until the list earns money.

Sender's free plan covers 2,500 subscribers and 15,000 emails a month with automation, ten landing pages, and popups included, so the entire operation runs at zero cost with only a footer credit as the price.

Small ecommerce store watching every subscription

Cart abandonment and post-purchase flows are needed, plus occasional SMS for time-sensitive offers, and Klaviyo's pricing is out of reach.

Standard at single-digit dollars carries the automation, the SMS, A/B testing, and ecommerce revenue reporting, at a fraction of what a dedicated ecommerce marketing platform charges for the same list.

Startup that wants one vendor for newsletters and receipts

A small product sends a monthly update and a handful of transactional notifications, and standing up two vendors for that volume feels absurd.

Sender's transactional API and SMTP are included on every plan including free, so both jobs run from one account, with the caveat that a serious transactional dependency should still move to Postmark or Resend.

EU business wanting a European vendor

Procurement prefers an EU-established processor and the budget will not stretch to the larger European platforms.

Sender is a Lithuanian company operating under EU law, which shortens the GDPR conversation, at a price well below the EU-based alternatives.

Pricing

from $0 free for 2,500 subscribers, then from $7 a month (Standard)

Subscriber-based subscription with a monthly send allowance set as a multiple of list size, priced on a slider rather than in a published static table. Prepaid email credits are available as an alternative for occasional senders.

PlanPriceIncludes
Free Forever$0
per month
  • 2,500 subscribers and 15,000 emails a month
  • Automation workflows included
  • 10 landing pages, popups, and forms
  • Transactional email API and SMTP
  • Sender branding in the footer; no SMS, A/B testing, or advanced reports

The most generous free tier in this category by a clear margin, and the reason most people try Sender at all.

StandardFrom $7
per month, scaling with subscriber count
  • Send allowance of 12x your subscriber count per month
  • 3 team seats
  • Branding removed and unlimited custom templates
  • SMS marketing and A/B testing
  • Advanced ecommerce reports

The $7 figure is the entry point on the slider, not a flat rate. Read the slider for your own list size before budgeting.

ProfessionalFrom $14
per month, scaling with subscriber count
  • Send allowance of 24x your subscriber count per month
  • 10 team seats and included SMS credits
  • Advanced automation and priority support
  • Reporting by subscriber group and by inbox provider
  • Dedicated IPs available

Dedicated IP access this far down a price ladder is unusual, though it is only worth taking at real volume.

EnterpriseCustom
quoted
  • Unlimited email sending
  • SAML v2 single sign-on and advanced permissions
  • Activity logs and an SLA
  • Phone support and a dedicated success manager

Add-ons

  • Prepaid email credits ($29 for 5,000 emails, roughly $5.80 per 1,000): For occasional senders who do not want a monthly subscription; covers all features including SMS and advanced automation.

Billing notes

  • Price is set on a slider by subscriber count rather than published as a static table of bands, so the $7 and $14 headline figures are the entry points at small list sizes and not the price at scale. Read the slider for your own number before committing.
  • Send volume is capped by a multiplier rather than sold as an allowance: twelve times your subscriber count a month on Standard and twenty-four times on Professional. A 10,000-subscriber list gets 120,000 or 240,000 sends respectively.
  • The free plan's 15,000 emails a month against 2,500 subscribers is effectively a six times multiplier, which is tighter than the paid tiers but generous in absolute terms.
  • Annual billing carries a 30 percent discount advertised for first-time buyers, taking Standard to $84 a year and Professional to $168 a year at the entry point.
  • Transactional email is included on every plan, including free, rather than sold as a separate meter. That is genuinely unusual at this price and removes a second subscription for low-volume application mail.
  • Prepaid credits at $29 for 5,000 emails, about $5.80 per 1,000, are an alternative for businesses that send a few times a year and do not want a recurring charge. Note this is roughly fifty times the per-email cost of a transactional provider, so it is only sensible for marketing sends.
  • Enterprise is the only tier with unlimited sending, SSO, and an SLA, and it is quoted rather than published.

Value assessment: At the volumes this directory compares, Sender is the cheapest credible option on the list. A 1,000-subscriber list is entirely free, including automation, landing pages, and popups, where Constant Contact would charge $30 to $110 and AWeber $20 to $45. A 10,000-subscriber list moves onto a paid tier whose price the slider sets from the $7 and $14 entry points, and which in practice lands well below the $120 to $275 Constant Contact charges and the $100 to $135 AWeber charges at the same size. Fifty thousand subscribers likewise sits far below the $430 to $575 range at Constant Contact. The send multipliers of twelve and twenty-four times are competitive, sitting between Constant Contact's ten to twenty-four and AWeber's ten to twelve. What the low price does not buy is depth: the automation is a tier below the serious platforms, the reporting is thinner, there are no events or webinars, and support is a small queue rather than an organisation. For a business whose email needs are a newsletter, a welcome flow, a cart recovery sequence, and occasional SMS, Sender delivers all of it for less than anything else here.

Strengths & limitations

Strengths

  • The most generous free tier in the category: 2,500 subscribers and 15,000 emails a month with automation, landing pages, and popups intact rather than stripped out.
  • Paid plans starting at single-digit dollars with a 30 percent annual discount, undercutting almost every competitor at the same list size.
  • Transactional email API and SMTP included on every plan including free, which no other budget marketing platform offers.
  • Automation workflows available on the free plan, where most competitors reserve them for paid tiers.
  • SMS and email combined inside a single automation flow rather than run as separate channels.
  • Dedicated IP access on the Professional tier, which is far lower down the ladder than most platforms gate it.
  • Bootstrapped and independently owned since 2012 with no acquisition and no outside capital, so there is no investor pressure to reprice.
  • EU-established as a Lithuanian company, which shortens GDPR conversations for European buyers.

Limitations

  • Pricing above the entry point is set on a slider rather than published as a static table, which makes budgeting for a large list harder than it should be.
  • Automation is competent but a clear tier below ActiveCampaign, Klaviyo, and Omnisend on conditional logic and ecommerce personalisation.
  • A team of roughly thirty people supporting over 180,000 accounts means support is a ticket queue on the lower tiers, with phone support only on Enterprise.
  • The transactional feature is a convenience rather than infrastructure: no message stream separation, no inbound parsing, and nothing resembling Postmark's or Mailgun's logging and observability.
  • No events, webinars, courses, CRM, or website builder, so businesses consolidating a wider stack will need other tools alongside it.
  • Reporting is thinner than the incumbents', with the more useful breakdowns held back for the Professional tier.
  • Brand recognition and integration ecosystem are both much smaller than Mailchimp's or Constant Contact's, so third-party tools are less likely to have a native Sender connector.
  • Prepaid credits at roughly $5.80 per 1,000 emails are extremely expensive per message compared with any transactional provider, so do not use them for application mail.

Head-to-head comparisons

6 alternatives

Sender vs AWeber

from $0 free for 500 subscribers, then $12.49 a month billed annually (Lite)

Sender is dramatically cheaper: a free tier at 2,500 subscribers and 15,000 emails against AWeber's 500 and 3,000, and paid plans starting at $7 to $14 against $15 to $30. Sender also includes transactional email and SMS, and its automation is available on the free plan. AWeber counters with twenty-eight years of operating history, a much larger and better-regarded support organisation, RSS blog broadcasts, and Stripe-backed selling pages. If budget decides, Sender. If you want to phone someone, AWeber.

Full Sender vs AWeber comparison

Sender vs Constant Contact

from $12 a month (Lite, up to 500 contacts)

Not close on price. Constant Contact charges $30 to $110 at 1,000 contacts where Sender is free, and $120 to $275 at 10,000 where Sender is in single or low double digits. Sender's automation is also arguably better and it includes transactional sending. Constant Contact has event registration with ticketing, social and ads management, phone support, and local training, none of which Sender attempts. Buy Constant Contact for events and hand-holding; buy Sender for everything else.

Full Sender vs Constant Contact comparison

Sender vs Mailjet

from $0 for 6,000 emails a month, then $9 a month (Starter)

Both are cheap EU-based platforms that do marketing and transactional email in one account, but they meter differently. Mailjet prices on emails sent with unlimited contacts, which is far cheaper for a huge list mailed rarely. Sender prices on subscribers with a send multiplier, which is cheaper for a small list mailed often. Sender has better automation, landing pages, popups, and SMS; Mailjet has a much stronger transactional API with inbound parsing, sub-accounts, and proper message logs. Model your own send frequency, then pick.

Full Sender vs Mailjet comparison

Sender vs MailerLite

from $10.80/mo (Comfort, up to 500 subscribers, billed annually; $12 monthly)

The closest competitor and the fairest comparison. MailerLite has a more polished interface, a stronger template ecosystem, better documentation, and a larger company behind it. Sender gives away more on the free tier (2,500 subscribers against 1,000) and includes transactional email and SMS at prices MailerLite does not match. For most price-sensitive buyers the decision comes down to whether the extra free headroom matters more than the interface polish.

Full Sender vs MailerLite comparison

Sender vs EmailOctopus

from $9/mo (Pro, 500 subscribers, billed yearly; $10 monthly)

Both are budget-first and both are deliberately lean. EmailOctopus is simpler still, with a free tier around 2,500 subscribers and a reputation for being cheap and reliable rather than featureful. Sender includes SMS, landing pages, popups, and transactional email that EmailOctopus does not attempt, and its automation goes further. If you want the absolute minimum viable newsletter tool, EmailOctopus. If you want a complete small-business marketing platform at a similar price, Sender.

Full Sender vs EmailOctopus comparison

Sender vs Brevo

from $0 (free, 300 emails per day), then $9/mo on Starter at 5,000 emails

Brevo prices on emails sent with unlimited contacts and adds a CRM, transactional infrastructure, and SMS, making it the stronger single-vendor story for a business that also needs a sales pipeline. Sender prices on subscribers with a send multiplier and is cheaper for a small list mailed frequently, with a far more generous free tier. Brevo has the larger company and the deeper feature set; Sender has the better economics for a small list and a lighter, faster product to actually use.

Implementation & onboarding

Setup time
An hour or two. Sign up on the free plan, import or collect subscribers, authenticate a sending domain, and send. There is nothing gated behind a sales call and nothing that needs configuring before a first campaign.
Learning curve
Low. The product is deliberately conventional and anyone who has used another email platform will recognise every concept. The automation builder is the only part that rewards deliberate learning, and it is simpler than its competitors' by design.
Onboarding
Entirely self-serve. The free plan is the evaluation path and it is permanent, so there is no trial clock. Enterprise is the only tier requiring a conversation.
Migration notes
Contacts import as CSV and Sender reviews imports for permission, so lists of doubtful provenance are refused. Authenticate SPF, DKIM, and DMARC on your sending domain before the first campaign and start by mailing your most engaged segment, because a new sending identity has no reputation and a burst of bounces from a stale list is the fastest way to trigger a review. Automations, forms, landing pages, and segments do not migrate from another platform and must be rebuilt, which is quick given the product's simplicity. Because the free plan carries 2,500 subscribers, most small businesses can run both platforms in parallel during the cutover at no cost.

Platform, API & security

Platforms
Web applicationREST APISMTP relayWebhooks
API
REST API covering subscribers, groups, campaigns, and transactional sending, plus an SMTP relay for transactional mail and webhooks for subscription and delivery events. The transactional surface is functional but far thinner than a dedicated provider's, with no inbound parsing and no message stream separation.
Compliance
GDPR as an EU-established processorCAN-SPAMCCPA
Data residency
EU-based as a Lithuanian company operating under EU law, which is a structurally stronger GDPR position than US-headquartered competitors offer on self-serve plans.
SSO
SAML v2 single sign-on on the Enterprise tier only.
Security notes
TLS in transit, SPF, DKIM, and DMARC support for sending domains, and activity logs plus advanced permissions on the Enterprise tier. Imports are reviewed for permission and accounts with rising complaint rates are contacted, which is standard practice for any shared-IP platform and necessary given how cheap the free tier makes account creation.

Frequently asked questions

10 questions

What is Sender?

Sender is a marketing email and newsletter platform for small businesses, priced on subscriber count. It sends campaigns and automated flows to a list you own and includes a drag-and-drop builder, automation workflows, segmentation, popups and forms, landing pages, SMS marketing, and a transactional email API. It is a bootstrapped Lithuanian company founded in 2012 with a team of around thirty people.

How much does Sender cost?

The free plan covers 2,500 subscribers and 15,000 emails a month permanently. Standard starts at $7 a month and Professional at $14, with a 30 percent annual discount advertised for first-time buyers. Both scale with subscriber count on a slider rather than in a published table, so read the slider for your own list size. Enterprise is quoted. Prepaid credits are available at $29 for 5,000 emails.

Is Sender's free plan really free?

Yes, permanently, and it is the most generous in this category. It covers 2,500 subscribers and 15,000 emails a month with automation workflows, ten landing pages, popups, forms, responsive templates, and transactional email access included. What you give up is SMS, A/B testing, advanced reports, and branding removal, so a Sender footer credit appears on every message.

How many emails can I send on Sender?

Your allowance is a multiple of your subscriber count: twelve times a month on Standard and twenty-four times on Professional. A 10,000-subscriber list therefore gets 120,000 or 240,000 sends respectively. The free plan is capped at 15,000 emails against 2,500 subscribers, effectively six times. Only the Enterprise tier offers unlimited sending.

Does Sender do transactional email?

Yes, through a REST API and SMTP, included on every plan including free, which no other budget marketing platform offers. It is genuinely useful for low-volume application mail. It is not a substitute for Postmark, Resend, or Mailgun: there is no message stream separation, no inbound parsing, and nothing resembling their message logs and deliverability tooling. If transactional email is a serious dependency, buy a dedicated provider.

Do unsubscribed contacts count toward my Sender bill?

Sender bills on subscribers in your account, so the standard list-hygiene discipline applies: remove people you will never mail again rather than leaving them occupying a tier. Because the free plan carries 2,500 subscribers and the paid entry points are single-digit dollars, the financial consequence of a slightly untidy list is far smaller here than on Mailchimp or ActiveCampaign, where the same carelessness costs real money.

Can I send cold outreach with Sender?

No. Sender requires permission-based lists, reviews imports, and will suspend accounts whose complaint rates rise, as any platform sending from shared IP pools must. Cold prospecting belongs on a dedicated outreach tool running its own domains and inboxes. Attempting it on a cheap shared-pool platform damages delivery for every other customer and gets the account closed quickly.

How does Sender's automation compare with the bigger platforms?

It is a clear tier below ActiveCampaign, Klaviyo, and Omnisend on conditional logic, predictive features, and ecommerce personalisation. What it does well is cover the flows most small businesses actually build: a welcome series, a re-engagement sequence, cart recovery, and post-purchase follow-up, with email and SMS combinable in one flow. And it offers all of that on the free plan, which the bigger platforms do not.

Is Sender a safe vendor to depend on?

It is bootstrapped, profitable, and has operated since 2012 without outside investors, so there is no acquisition or repricing pressure of the kind Constant Contact and Mailchimp customers have experienced. The counterweight is scale: roughly thirty employees supporting over 180,000 accounts is very lean, support is a queue rather than an organisation, and the integration ecosystem is small. Keep your list exportable, as you should anywhere.

Is Sender good for GDPR compliance?

Structurally, yes. Sender is a Lithuanian company established in the EU and operating under EU law, which removes the transfer-mechanism conversation that US-headquartered platforms have to have with European procurement. The usual obligations still fall on you: a lawful basis for your list, double opt-in where required, and honouring erasure requests through the platform.

Editorial verdict

Sender is the best answer in this category to the question of how little you can pay. The free tier at 2,500 subscribers and 15,000 emails a month, with automation workflows, ten landing pages, popups, and a transactional API included, is more than several competitors give you on a paid plan, and the paid tiers start at single-digit dollars with SMS and A/B testing added. For a solo operator, a small ecommerce store, or any business under a few thousand subscribers, it is very hard to justify paying Constant Contact ten times as much for something that does the same job less generously. The limits are honest ones. The automation is a tier below the serious platforms, the reporting is thin until the Professional plan, there are no events or webinars, and roughly thirty people are supporting over 180,000 accounts, so support is a queue and the integration ecosystem is small. The transactional feature is a convenience, not infrastructure, and should not replace Postmark or Resend for a real dependency. Pricing above the entry point also lives on a slider rather than a published table, so read it for your own list before budgeting. Within those limits, this is the most email per dollar available to a small business today.
