Reclaim Vs. Blotout EdgeTag
Server Side
Retention uses Klaviyo SDK to write events; there is no server side integration
Compliance
Unclear
It is unclear how data is managed with Retention.com considering use of browser side technologies
Global
Blotout works as effectively globally as the US
Pricing
Expensive
Value Driven
For the limited feature set, and results, Retention would be 10x more expensive than Blotout

Klaviyo SDk is blocked, so is Retention
