Transparency alternatives to Mission Inbox
Other Transactional email and notifications vendors we measure, sorted by how much they publish that Mission Inbox does not. This is a comparison of disclosure, not of features or fitness.
12 shown of 30 that differ from Mission Inbox on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Mission Inbox has 9 gaps in what we could measure: Data processing agreement, Subprocessor list, Data location stated, Status page with history, Certifications named, Uptime SLA with a figure, No third-party tracking before consent, security.txt (RFC 9116), Notice before subprocessors change. The column “publishes and Mission Inbox does not” is the one that closes them.
