Retention.com now describes use cases beyond ecommerce, including publishers and ad tech. Define the identity input, returned data and permitted activation before selecting an alternative. A retail campaign and an identity infrastructure project need different evaluations.
We publish this comparison at Leadpipe. These are recommendations by use case, based on the linked vendor pages reviewed September 23, 2026. They are not results from a controlled vendor benchmark.
The buying decision
Write down whether you need a resolved identifier, an email audience or a sales-ready website visitor. Check overlap with existing records and how suppression propagates. Use outcome measurement that fits the destination, such as incremental purchases or qualified sales conversations.
Retention.com provides identity data for ecommerce, publishers, ad tech and retail. Current vendor reference. Clarify which identifiers are returned, the permitted use, region coverage and how deletion or suppression propagates to destinations.

What each option changes
Opensend: ecommerce identity
Opensend markets visitor identity and activation for businesses seeking to re-engage website audiences. Vendor reference.
Choose it for: A team evaluating visitor recovery as part of its lifecycle marketing process.
Verify before buying: Use a holdout to measure incremental conversion. Check overlap with existing subscribers, sending eligibility and the activation destination.
Customers.ai: ecommerce identity
Customers.ai currently emphasizes identity resolution and ecommerce email activation, including Klaviyo workflows. Vendor reference.
Choose it for: An ecommerce team working on audience recovery and lifecycle email.
Verify before buying: Inspect the returned identity, suppression behavior and ESP delivery. A retail email activation workflow differs from a B2B account-owned sales process.
FullContact: identity infrastructure
FullContact publishes enrichment and identity-resolution interfaces for linking known identifiers. Vendor reference.
Choose it for: A data or engineering team building identity resolution into its own product or data environment.
Verify before buying: Evaluate inputs, identifier persistence, permitted use and deletion behavior. API-level identity resolution and a ready-made visitor workflow require different implementation work.
Happierleads: visitor identification
Happierleads markets B2B visitor identification with company and person-level outputs. Vendor reference.
Choose it for: A team comparing visitor data with built-in qualification and follow-up options.
Verify before buying: Request evidence for each returned identity and confirm geographic coverage, required fields, suppression and actual destination support.
Compare costs on the same workload
Ask each shortlisted vendor to price your actual users, record volume, required fields, destinations and contract period. Separate the subscription from implementation, extra usage and the labor needed to accept a record. Do not compare a monthly equivalent on an annual agreement with a cancellable monthly subscription as if the commitment were identical.
A practical measure is total operating cost divided by unique accepted records. Define an accepted record before calculating it: current role and employer, required contact fields, relevant geography and no duplicate or suppression conflict. This is a purchasing metric, not a forecast of meetings or revenue. For website-driven work, our visitor identification pricing guide explains the separate cost components.
Run a decision-focused evaluation
| Step | Evidence to keep | Decision it supports |
|---|---|---|
| Define the job | Required input, output, owner and destination | Whether the candidate covers the required workflow |
| Use a representative sample | Target accounts or eligible traffic, with regions recorded | Whether coverage applies to your business |
| Review returned records | Accepted, rejected and unknown results with reasons | Whether output is usable without hiding failures |
| Complete the handoff | CRM fields, assigned owner and suppression behavior | Whether a rep can act on the record |
| Follow outcomes | Conversations, opportunities and cost in a defined window | Whether the workflow deserves a larger commitment |
Keep company identification, suggested contacts and matched visitors separate. The person-level versus company-level guide explains why these are different units. A provider returning more companies has not necessarily identified more people.
Where Leadpipe fits
Leadpipe supports both account-level and person-level workflows. Its IP to Company API retrieves stored company information from an IPv4 or IPv6 address; its separate Identification product supplies eligible visitor records and activity. Choose company context for account research and person-level output when the action requires a specific visitor. A company lookup returns no people or visits. Confirm API eligibility and its separate lookup allowance in the official documentation.
Person-level coverage is strongest in the US. EU/UK traffic defaults to company-level identification; person-level requires affirmative consent. Fields can be missing, so judge required output on your actual traffic. If you need research signals from outside your website, evaluate Orbit separately and check its audience allowances.
The current pricing page lists Pro 500 at $147/month for 500 identification credits. The trial is 7 days or 500 profiles, whichever comes first, no card. Confirm the delivery and data-use requirements of your chosen plan.
Use the vendor evaluation kit to record the same acceptance criteria for every candidate. Start a Leadpipe trial when website identification is the requirement you want to measure.
FAQ
What is the best Retention.com alternative?
The best fit depends on the job being replaced. Use the table above to distinguish research, identification and execution. Require each candidate to complete the workflow using your own input and acceptance criteria before choosing a subscription.
Can Leadpipe replace Retention.com?
Leadpipe fits the website visitor-identification part of a sales workflow. It is not a complete replacement when you also require a contact database, conversation platform, email sender, advertising system or broader account orchestration. Scope the replacement around the capabilities you use.
How should we measure a successful switch?
Measure incremental accepted output, successful delivery and operating cost first. Follow the resulting cohort into conversations and opportunities using the same observation window. Do not treat a vendor feature list or an advertised match rate as proof of revenue impact.
