# Opensend

> Opensend is an identity resolution platform for direct-to-consumer ecommerce brands that identifies anonymous US website visitors against a proprietary graph of more than 200 million consumer profiles, then delivers those identities into email platforms such as Klaviyo, programmatic ad networks, and SMS flows so a brand can retarget shoppers who never gave an address; it identifies roughly 25 to 35 percent of anonymous visitors, prices per identity delivered from $400 a month, and is US-only.

## Overview

Opensend is the consumer-side member of this category, and including it alongside the B2B tools is deliberate: it runs exactly the same technique, an identity graph matched against anonymous sessions, but aimed at Shopify brands rather than sales teams. Founded in 2022 and based in Los Angeles, it identifies the shoppers browsing a DTC store and hands them back as contactable identities so a brand can send a browse-abandonment email or run a retargeting audience against people who never entered their address.

The identity graph is the asset. Opensend describes a network of more than 200 million US consumer profiles, drawn from what it characterises as thousands of sites with millions of registered users who consent to partner marketing, processing over seven billion events daily across more than 100,000 US-based sites. Against that network the company cites a 73 percent match rate for US shoppers, while the practical figure it publishes for anonymous site visitors identified is 25 to 35 percent. Those two numbers measure different things and it is worth keeping them apart: the first is coverage of the network, the second is what you should expect to see on your own traffic.

The product is organised around four solutions. Connect identifies and converts high-intent visitors. Reconnect maintains recognition across devices and browsers, which is the specific problem that breaks most consumer retargeting. Ignite improves the quality of existing customer data. Personas applies AI-powered segmentation so identified shoppers can be grouped for targeted campaigns rather than dumped into one flow. Activation runs across three channels: triggered email flows through your existing marketing platform, programmatic advertising across millions of sites, and triggered SMS.

Pricing is per identity delivered, which is the honest structure for this kind of tool. Tier one is $400 a month for 2,000-plus identities at $0.20 each, tier two is $800 for 4,300-plus at $0.186, tier three is $1,600 for 9,500-plus at $0.168, and annual billing saves 20 percent across the board. Unused monthly credits roll over. There is a $1 fourteen-day trial, and setup is a pixel, a Shopify app, or a server-side integration that most teams complete in well under ten minutes. In March 2026 Opensend acquired Fueled.io, a first-party data activation company, extending it further into customer data infrastructure.

## How it works

1. You install Opensend on your store: a pixel, the Shopify app, or a server-side integration, depending on your setup. The company states most teams are operational in under five to ten minutes.

2. As shoppers browse, sessions are matched against Opensend's identity graph of more than 200 million US consumer profiles, built from a network the company describes as thousands of sites with millions of registered users who have consented to partner marketing. The graph processes more than seven billion events daily across 100,000-plus US sites.

3. Matched sessions are delivered back to you as identities, and you are billed per identity delivered rather than per session or per seat. In practice the company publishes an expectation of 25 to 35 percent of anonymous visitors identified.

4. Reconnect handles the cross-device problem: the same shopper browsing on a phone at lunch and a laptop at night is recognised as one person rather than two anonymous sessions, which is the single largest failure mode in consumer retargeting.

5. Personas applies AI-powered segmentation to the identified population so a first-time browser, a repeat visitor, and a cart abandoner are treated as different audiences rather than fed into one generic flow.

6. Activation happens in three channels. Identities flow into your existing email platform (Klaviyo being the primary path) to trigger browse and cart abandonment flows, into programmatic ad networks for re-engagement across millions of sites, and into SMS for triggered messages to previously unrecognised sessions. Ignite runs alongside, improving the quality of the customer data you already hold.

## Best for

US direct-to-consumer ecommerce brands on Shopify with meaningful traffic and an existing Klaviyo or equivalent email programme, particularly those whose conversion rate is low enough that recovering a share of anonymous browsers materially changes revenue.

## Not the right fit for

- B2B companies. This is a consumer identity graph aimed at shoppers, and a B2B site pointing it at business buyers is using the wrong dataset entirely; Leadpipe, Vector, and the company-level European tools cover that ground.
- Anyone outside the United States. The network is explicitly a US shopper graph, so non-US traffic will not resolve and the subscription buys nothing.
- Low-traffic stores. The entry tier assumes 10,000 to 50,000 monthly visitors and delivers 2,000-plus identities; below that volume the $400 monthly floor is very expensive per recovered shopper.
- Brands with a cautious stance on consumer privacy or a sensitive category. Emailing someone who browsed but never gave you an address is legal in the vendor's framing and uncomfortable in many customers' framing, and the backlash risk is real.
- Teams without an email or SMS programme already running. Opensend delivers identities; it does not send for you, so a brand with no Klaviyo flows has nothing to plug the output into.

## Features

### Identity resolution

The graph and the matching, which is the whole product beneath the packaging.

- **200 million-plus US consumer profiles**: A proprietary identity graph the company describes as consent-based, sourced from thousands of sites with millions of registered users who consented to partner marketing.
- **Seven billion daily events across 100,000-plus sites**: The scale of the signal feeding the graph, which is what keeps a consumer identity network current rather than stale.
- **25 to 35 percent of anonymous visitors identified**: The figure to plan against. The separately quoted 73 percent USA shopper match rate describes network coverage, not what you will see on your own traffic.
- **Connect**: The core solution: identifying and converting high-intent visitors who never submitted an email address.
- **Reconnect**: Maintains recognition of the same shopper across devices and browsers, addressing the fragmentation that quietly wrecks most consumer retargeting.
- **Ignite**: Enhances the quality of the customer data you already hold rather than only adding new identities to it.

### Segmentation and audience building

Ensuring identified shoppers are not all treated the same.

- **Personas AI segmentation**: AI-powered grouping of identified shoppers for targeted campaigns, so a first-time browser and a cart abandoner receive different treatment.
- **High-intent visitor prioritisation**: The product is positioned around identifying high-intent visitors specifically rather than resolving every session indiscriminately.
- **Cross-device audience consolidation**: Identities unified across devices feed cleaner audiences into email, SMS, and ad platforms.
- **First-party data asset building**: The strategic pitch is that identified shoppers accumulate into an owned first-party data asset rather than a rented ad audience, which matters as third-party cookies decline.

### Activation channels

Three ways to reach an identified shopper, all through tools you already run.

- **Triggered email flows**: Identities push into your existing email marketing platform to trigger browse abandonment and cart abandonment flows, with Klaviyo as the primary integration path.
- **Programmatic advertising**: Re-engagement across millions of websites using identified shoppers as the audience rather than a probabilistic retargeting pool.
- **Triggered SMS**: SMS flows aimed at previously unrecognised sessions, for brands whose customers respond better to text than email.
- **Meta, Google, and TikTok audiences**: Identified shoppers push into the major consumer ad platforms as matched audiences.
- **Fueled.io data activation**: The March 2026 acquisition of Fueled.io, a first-party data activation company for ecommerce, extends Opensend from identification into broader customer data activation.

### Setup and commercial model

Deliberately frictionless, with a pricing structure that is honest about what you are buying.

- **Shopify app installation**: A native Shopify path alongside a standard pixel and a server-side integration option, with setup stated at under five to ten minutes.
- **Per-identity pricing**: You are billed on identities delivered rather than sessions or seats, at $0.20, $0.186, and $0.168 per identity across the three published tiers.
- **Credit rollover**: Unused monthly credits roll over rather than expiring, which smooths seasonal traffic swings for a retail business.
- **One dollar trial**: A fourteen-day trial for $1 rather than a free tier, which is low enough friction to count as self-serve evaluation.
- **Annual discount**: Twenty percent off across all tiers for annual billing, dropping the entry tier from $400 to $320 a month.

### Compliance and data handling

The area where a consumer identity product deserves the closest reading.

- **Consent-based sourcing claim**: The company states its network consists of users who explicitly consented to partner marketing, which is the basis of its legal position.
- **US-only scope**: The graph is a US shopper network, which keeps the product outside GDPR territory by not operating there rather than by complying there.
- **End-to-end encryption**: The company cites end-to-end encryption and security protocols for the data it handles.
- **Stated legal compliance**: Opensend describes itself as fully legally compliant and following applicable laws and regulations, though it publishes less specific detail on opt-out mechanics than some competitors in the B2B tier do.

## Use cases

- **Shopify brand with a two percent conversion rate**: Forty thousand shoppers a month browse, 98 percent leave without buying or giving an email address, and the Klaviyo list only grows from people who already opted in. Outcome: Opensend identifies a quarter to a third of the anonymous traffic, browse and cart abandonment flows fire against people who were previously invisible, and the recovered revenue is measured directly against a $400 monthly cost.
- **Performance marketer losing shoppers across devices**: A customer browses on mobile at lunch and returns on a laptop in the evening, and both sessions look like separate anonymous strangers to every existing tool. Outcome: Reconnect resolves both to one identity, so the retargeting audience and the email flow treat them as a single returning shopper rather than double-serving two ghosts.
- **Brand building an owned first-party data asset**: Third-party cookie deprecation and rising ad costs mean rented audiences are getting worse and more expensive every quarter. Outcome: Identified shoppers accumulate into an owned contact base that feeds email, SMS, and matched ad audiences, and Ignite improves the quality of the customer records already held, reducing dependence on ad platform targeting.
- **Seasonal retailer with uneven traffic**: November traffic is five times August traffic, and a fixed monthly credit allowance either wastes money in summer or runs out in the run-up to Christmas. Outcome: Credit rollover carries unused summer allowance into the peak, so the plan can be sized to the annual average rather than to the worst month.

## Pricing

Usage-based monthly subscription priced per identity delivered, tiered by expected monthly visitor volume, with unused credits rolling over and a 20 percent discount for annual billing.

- **Tier 1**: $400 per month ($320 billed annually). 2,000-plus identities delivered; $0.20 per identity; Sized for 10,000 to 50,000 monthly visitors; All platform integrations included; Unused credits roll over. The entry point, and expensive per identity relative to the higher tiers.
- **Tier 2**: $800 per month ($640 billed annually). 4,300-plus identities delivered; $0.186 per identity; Sized for 50,000 to 150,000 monthly visitors; Klaviyo, Meta, Google, and TikTok integrations; Credit rollover. The most commonly chosen tier, per the vendor's own labelling.
- **Tier 3**: $1,600 per month ($1,280 billed annually). 9,500-plus identities delivered; $0.168 per identity; Sized for 100,000 to 300,000 monthly visitors; Full activation across email, programmatic ads, and SMS; Credit rollover.
- **Enterprise**: Custom contact required. Volumes above tier three; Custom identity allowances; Bespoke commercial terms; Full platform access; Not a self-serve purchase.

Billing notes:

- Pricing is per identity delivered, so you are billed for output rather than for traffic or seats, which is the fairest meter in this category.
- The per-identity rate improves only modestly with volume, from $0.20 to $0.168, which is a shallower discount curve than most usage-priced competitors offer.
- Annual billing saves 20 percent across all tiers, taking the entry price from $400 to $320 a month.
- Unused monthly credits roll over rather than expiring, which is genuinely useful for a seasonal retail business and rare in this category.
- The trial is $1 for fourteen days rather than free, which is nominal friction but does mean there is no permanently free way to evaluate.
- Tier selection is guided by monthly visitor bands (10,000 to 50,000, 50,000 to 150,000, 100,000 to 300,000), so the plan is chosen on traffic even though billing is on identities.

Value assessment: The arithmetic here is unusually easy to run, which is the best thing about Opensend's pricing. At $0.20 per identity on the entry tier, the question is simply whether an identified shopper who was previously invisible produces more than twenty cents of incremental revenue through a browse abandonment flow. For most DTC brands with a functioning Klaviyo programme and reasonable margins, it clearly does, and credit rollover means seasonal traffic does not punish you. What the pricing does not tell you is the softer cost. Emailing someone who browsed and never gave you an address is a brand decision as much as a marketing one, and a poorly judged first message can cost more in complaints and unsubscribes than the recovered revenue is worth. The tool is good value; whether it is a good idea depends on your category and your customers.

## Strengths

- The clearest unit economics in the category: priced per identity delivered at published rates, so return on investment is a straightforward calculation rather than an act of faith.
- Credit rollover means unused allowance carries forward, which suits the seasonal traffic patterns that define retail and which almost no competitor offers.
- Reconnect's cross-device recognition addresses the specific failure that makes most consumer retargeting inaccurate, rather than only adding more identities.
- Genuinely fast setup through a native Shopify app, a pixel, or a server-side integration, with a stated time to live of under ten minutes.
- Three activation channels (email, programmatic advertising, and SMS) through the tools a brand already runs, rather than requiring a new sending platform.
- A large and actively fed identity graph: more than 200 million US consumer profiles with over seven billion events daily across 100,000-plus sites.
- The March 2026 acquisition of Fueled.io extends the company into first-party data activation, which is the right strategic direction as third-party cookies decline.

## Limitations

- US-only. The identity network is a US shopper graph, so any brand with significant international traffic is paying for coverage that will not resolve.
- Consumer-focused, which makes it the wrong product for B2B entirely rather than a weaker option for it.
- The $400 monthly floor is high for a small store, and the entry tier assumes 10,000 to 50,000 monthly visitors before the economics work.
- Published opt-out mechanics are thinner than the leading B2B vendors provide; the compliance position rests on a consent-based sourcing claim rather than on documented consumer-facing controls.
- The gap between the 73 percent network match rate and the 25 to 35 percent of anonymous visitors actually identified is easy to conflate, and the marketing does not always separate them clearly.
- The per-identity discount curve is shallow, from $0.20 to $0.168, so scale brings less relief than usage-priced competitors typically give.
- Contacting shoppers who never gave you their address carries genuine brand risk, and this is a decision that deserves a discussion beyond the marketing team.
- No free tier, only a $1 trial, and no published security certifications such as SOC 2.

## Comparisons

- **Opensend vs Leadpipe**: Both are US-only person-level identification tools built on consented identity graphs, but aimed at different buyers. Leadpipe covers B2B and B2C with 62-plus fields per person, an API, and 200-plus integrations from $147 a month; Opensend is purpose-built for DTC ecommerce with Shopify and Klaviyo as first-class paths and per-identity pricing from $400. Choose Opensend if you run a Shopify store; choose Leadpipe if you sell to businesses, or to both.
- **Opensend vs Vector**: The same technique aimed at opposite markets. Vector identifies B2B visitors and turns them into LinkedIn, Google, Meta, and Reddit audiences with Ad Reveal naming your ad clickers, from $399 a month. Opensend identifies consumers and routes them into Klaviyo email, programmatic ads, and SMS, from $400. There is no meaningful overlap in who should buy them: the decision is entirely whether your customers are companies or shoppers.
- **Opensend vs Snitcher**: Snitcher is the opposite end of this category in every dimension: European, company-level, GDPR legitimate-interest, EU-hosted, and from $49 a month with unlimited seats. Opensend is US-only, person-level, consumer-focused, and from $400. If you sell to businesses in Europe, Snitcher's IP-to-company model is right and Opensend's consumer graph is irrelevant; if you sell to US shoppers, the reverse holds absolutely.

## Implementation

- Setup time: Under ten minutes for installation: install the Shopify app, drop the pixel, or wire the server-side integration, then connect your email platform. The real work is designing the flows the identities feed into, which is a Klaviyo project rather than an Opensend one.
- Learning curve: Low as software, and the hard part is judgement rather than mechanics. Deciding what a first message to someone who never gave you their address should say, and how aggressive to be, matters far more to the outcome than any configuration in the tool.
- Onboarding: Self-serve through a $1 fourteen-day trial, with a demo available for teams that want one and enterprise volumes handled through sales. The published setup path is access account, install pixel or app, connect email platform, and begin.
- Migration: Additive rather than a system of record, so nothing needs importing. The consideration specific to Opensend is suppression: identified shoppers will overlap with people already on your list, and you need your email platform's suppression and deduplication working properly before you switch flows on, or existing customers will receive messages intended for strangers. Test with a small segment first rather than enabling every flow at once.

## Platform, API & security

- Platforms: Shopify app, JavaScript pixel for any store, Server-side integration, Web dashboard
- API: Integration is primarily through plug-and-play connectors to Shopify, Klaviyo, major email service providers, ad platforms, and analytics tools; a broad public API is not a headline part of the published product surface.
- Compliance: Stated full legal compliance with applicable US laws and regulations, Consent-based data sourcing, per the vendor: network users explicitly consented to partner marketing, US-only operation, which places the product outside GDPR territory rather than compliant within it
- Data residency: United States. The product operates on a US consumer identity network and no international or EU option is offered.
- SSO: Not published as a standard feature.
- Security notes: Opensend cites end-to-end encryption and security protocols, and bases its legal position on the claim that its network consists of users who consented to partner marketing. What it publishes less of, relative to the stronger B2B vendors in this category, is specific consumer-facing opt-out mechanics and independent security certification such as SOC 2. For a product whose entire function is contacting people who did not give you their address, those are the questions worth raising directly with the vendor before signing.

## Support

- Channels: Email support, In-app support, Demo and onboarding assistance available
- Documentation: Product documentation covering pixel and Shopify app installation, server-side integration, email platform connection, and activation channel setup.
- Community: No large public user community; the company publishes ecommerce and identity resolution content on its own site.

## FAQ

### What is Opensend?

Opensend is an identity resolution platform for direct-to-consumer ecommerce brands. It identifies anonymous US shoppers browsing your store against a proprietary graph of more than 200 million consumer profiles, then delivers those identities into your email platform, programmatic ad networks, and SMS so you can reach people who never gave you an address. It is the consumer-market equivalent of B2B website visitor identification.

### How much does Opensend cost?

Pricing is per identity delivered across three tiers: $400 a month for 2,000-plus identities at $0.20 each, $800 for 4,300-plus at $0.186, and $1,600 for 9,500-plus at $0.168, with an enterprise tier above. Annual billing saves 20 percent, taking the entry tier to $320 a month. Unused credits roll over, and there is a fourteen-day trial for $1.

### What percentage of visitors will Opensend identify?

Plan on 25 to 35 percent of anonymous visitors, which is the figure the company publishes for site traffic. The separately quoted 73 percent USA shopper match rate is a different measurement: it describes coverage of the identity network, not what you should expect on your own store. Keeping those two numbers apart is the most important thing to understand about Opensend's marketing.

### Does Opensend work outside the United States?

No. The identity graph is a US consumer network, so international traffic will not resolve. Any brand with substantial non-US traffic is paying for coverage it will not receive, and there is no European equivalent within the product because the underlying technique would run straight into GDPR.

### Is it legal to email someone who never gave me their email address?

Opensend's position is that its network consists of users who explicitly consented to partner marketing, which is the basis for its claim of full legal compliance under US rules. That is a real legal argument and it is also a brand decision separate from the legal one. A poorly judged first message to someone who only browsed can generate complaints and unsubscribes that cost more than the recovered revenue, so the message design deserves as much attention as the tool selection.

### What is Reconnect and why does it matter?

Reconnect maintains recognition of the same shopper across devices and browsers. A customer who browses on a phone at lunch and returns on a laptop that evening looks like two separate anonymous strangers to almost every tool, which produces double-served ads and duplicated flows. Resolving both sessions to one identity is often worth more than simply adding raw identification volume.

### Do I need Klaviyo to use Opensend?

Not strictly, but you need something. Opensend delivers identities; it does not send messages for you. Klaviyo is the primary integration path and the assumed setup for most customers, but other major email service providers are supported, alongside programmatic ad networks and SMS. A brand with no email or SMS programme running has nothing to plug the output into and should build that first.

### How does credit rollover work and why does it matter?

Unused monthly identity credits carry forward rather than expiring. For a retail business this is genuinely valuable: November traffic can be several times August traffic, and without rollover you either waste allowance in quiet months or run short at peak. Rollover means you can size the plan to your annual average rather than to your worst month, and very few competitors in this category offer it.

### How is this different from B2B visitor identification tools?

The technique is identical and the dataset is opposite. B2B tools match against business identity graphs or IP-to-company databases and return companies or business contacts; Opensend matches against a consumer shopper network and returns individual shoppers with consumer contact details. Pointing a B2B tool at a Shopify store, or Opensend at a SaaS site, produces poor results not because either is bad but because the graph is wrong for the traffic.

### Who is behind Opensend?

Opensend was founded in 2022 and is headquartered in Los Angeles. Its funding history is not publicly detailed and sources conflict on whether it has raised external capital, with no round size disclosed. In March 2026 it acquired Fueled.io, a first-party data activation company for ecommerce brands, extending the platform beyond identification into broader customer data infrastructure.

## Editorial verdict

Opensend is the cleanest expression of this category's economics because the maths is right there on the pricing page: twenty cents per identified shopper, and either a browse abandonment flow earns that back or it does not. For a US Shopify brand with a working Klaviyo programme and 10,000-plus monthly visitors, it usually does, and credit rollover plus a ten-minute setup make it unusually low-risk to test for a dollar. Reconnect's cross-device resolution is the underrated feature, fixing an accuracy problem rather than only adding volume. The reservations are not really about the software. It is US-only, so international traffic buys nothing; the $400 floor is steep for a small store; published opt-out mechanics and security certifications are thinner than the leading B2B vendors offer; and messaging people who browsed but never gave you an address is a brand decision that belongs to more than the marketing team. If you sell to shoppers in America and have thought that decision through, this is the right tool for it. If you sell to businesses, everything else in this category is a better fit.
