Transparency alternatives to Klaviyo
Other Email marketing vendors we measure, sorted by how much we found at them and not at Klaviyo. This is a comparison of disclosure, not of features or fitness.
12 shown of 32 that differ from Klaviyo on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Klaviyo has 5 gaps in what we could measure: Data location stated, Uptime SLA with a figure, No third-party tracking before consent, security.txt (RFC 9116), Named privacy contact. The column “Found there, not found at Klaviyo” is the one that closes them.
