Other Transactional email and notifications vendors we measure, sorted by how much they publish that Copernica does not. This is a comparison of disclosure, not of features or fitness.
12 shown of 23 that differ from Copernica on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Copernica has 9 gaps in what we could measure: Data processing agreement, Subprocessor list, Data location stated, Certifications named, Uptime SLA with a figure, No third-party tracking before consent, security.txt (RFC 9116), Notice before subprocessors change, Named privacy contact.
