Alternatives to Ably
Other Transactional email and notifications vendors we measure, sorted by how much they publish that Ably does not. This is a comparison of disclosure, not of features or fitness.

Ably has 6 gaps in what we could measure: Data processing agreement, Subprocessor list, Data location stated, Certifications named, No third-party tracking before consent, Notice before subprocessors change. The column “publishes and Ably does not” is the one that closes them.
