Alternatives to Courier
Other Transactional email and notifications vendors we measure, sorted by how much they publish that Courier does not. This is a comparison of disclosure, not of features or fitness.
12 shown of 23 that differ from Courier on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Courier has 7 gaps in what we could measure: Data processing agreement, 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 “publishes and Courier does not” is the one that closes them.

Only criteria we could measure for both are counted. Where we could measure one and not the other, the row is silent: that would be a statement about our measurement, not about either vendor. Every single result with its source is on the two profiles.
