If you are SaaS product teams
A SaaS product sends on behalf of its customers, so the deciding factors are tenant isolation, whether suppressions can be scoped rather than global, and whether support can answer why one specific account did not receive one specific email. Lifecycle automation and transactional sending usually need to coexist.
The order above is the general editorial ranking. Re-sorted against multi-tenant support, event stream, and the suppressions API, the shortlist for trial expiry notices, dunning, onboarding sequences, and per-tenant transactional mail becomes Buttondown, Loops, and Kit. That differs from the headline order, which weighs all audiences together.
