Transparency alternatives to ClickSend
Other Transactional email and notifications vendors we measure, sorted by how much we found at them and not at ClickSend. This is a comparison of disclosure, not of features or fitness.
12 shown of 30 that differ from ClickSend on at least one criterion we measured for both. Public transparency score, not a product or security rating.
ClickSend has 7 gaps in what we could measure: Data processing agreement, Subprocessor list, Data location stated, Uptime SLA with a figure, HTTPS enforced with HSTS, No third-party tracking before consent, security.txt (RFC 9116). The column “Found there, not found at ClickSend” is the one that closes them.
