Transparency alternatives to Stream
Other Transactional email and notifications vendors we measure, sorted by how much we found at them and not at Stream. This is a comparison of disclosure, not of features or fitness.
12 shown of 30 that differ from Stream on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Stream has 6 gaps in what we could measure: Data processing agreement, Data location stated, Uptime SLA with a figure, No third-party tracking before consent, security.txt (RFC 9116), Notice before subprocessors change. The column “Found there, not found at Stream” 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.
