Alternatives to Sendmarc
Other Email security vendors we measure, sorted by how much they publish that Sendmarc does not. This is a comparison of disclosure, not of features or fitness.
12 shown of 34 that differ from Sendmarc on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Sendmarc has 7 gaps in what we could measure: Subprocessor list, Data location stated, Status page with history, Public pricing, Uptime SLA with a figure, security.txt (RFC 9116), Named privacy contact. The column “publishes and Sendmarc does not” is the one that closes them.
