Transparency alternatives to SMTP2GO
Other Transactional email and notifications vendors we measure, sorted by how much we found at them and not at SMTP2GO. This is a comparison of disclosure, not of features or fitness.
12 shown of 30 that differ from SMTP2GO on at least one criterion we measured for both. Public transparency score, not a product or security rating.
SMTP2GO has 8 gaps in what we could measure: Data processing agreement, Subprocessor list, Certifications named, Uptime SLA with a figure, No third-party tracking before consent, security.txt (RFC 9116), Notice before subprocessors change, Named privacy contact. The column “Found there, not found at SMTP2GO” is the one that closes them.
