Comparison scope
This page compares Attribuly Capture and ReCapture with Retention.com Reclaim. The $0.15 per-email rate shown below is published on the Retention.com DTC solutions page; retention.com/pricing redirects to account registration, and Retention.com’s help center separately references monthly plan tiers, so a quoted plan may differ from the per-email rate.
The 30-second version
Our assessment, based on publicly available product documentation.
Choose Attribuly when you prioritize
- Recovery timing matters — your abandonment flows need to fire while the shopper is still in the session, not on the next daily send
- You need the attribution scope, window and deduplication rule written down before you trust the revenue number
- You would rather pay against the estimated recovery opportunity than per email delivered
Choose Retention.com when you prioritize
- You want no contract at all — month to month, cancel anytime, published as such
- You would rather pay a known unit rate per email than a monthly platform fee
- You want the identified emails as records you own, not only as activity inside a workflow
Where they overlap
- Resolving anonymous sessions to a contactable email address
- Dedicated Klaviyo metrics for browse, cart and checkout abandonment
- Cloned-flow setup with filters to prevent duplicate sends
- Suppression against shoppers already on your list

We compare identity tools on the full path from a missed shopper to measurable revenue. Most tools in this category cover part of it — the differences are in how far each one goes and how the result is measured.

Switching from Retention.com
Both platforms require changes to Klaviyo flow architecture, and both use cloned flows with exclusion filters, so the flow work is structurally similar. The two variables worth modeling are timing and unit economics: Retention.com documents daily record delivery and bills per email, while Attribuly passes events during the session and prices against the estimated recovery opportunity. Migration effort depends on the store’s existing setup.

Attribuly vs Retention.com FAQ
Is Retention.com a direct alternative to Attribuly?
They overlap on identifying anonymous shoppers and triggering Klaviyo abandonment flows, and Retention.com publishes dedicated Reclaim metrics for Viewed Product, Added to Cart and Checkout Started. The clearest structural difference is delivery timing: Retention.com’s help center states records are sent once per day, while Attribuly is built to pass events into Klaviyo as the session happens.
What does Retention.com cost?
The DTC solutions page publishes $0.15 per email with 1,000 emails included each month, on no contract and month-to-month billing. Retention.com’s help center separately references monthly plans from $19 to $999 and above, so the rate you are quoted may depend on which offer you enter through.
Does Retention.com require changes to existing Klaviyo flows?
Yes. The setup documentation describes cloning your existing browse abandonment flow, switching the trigger to the Reclaim metric, and adding filters so shoppers who already received the native flow are excluded. Attribuly documents a comparable parallel server-side flow with a delay and conditional split — neither tool avoids flow work entirely.
Why does daily delivery matter for abandonment flows?
Abandonment flows are timing-sensitive: a browse or cart reminder sent within the hour reaches a shopper who still remembers the product, while one sent the next day competes with everything else in the inbox. Retention.com documents sending records once per day. Whether that is acceptable depends on the flow — it matters less for reactivation than for checkout recovery.
