SMTP.com

SMTP.com is a long-running SMTP relay and transactional email delivery provider now associated with Ziff Davis. It is relevant to the provider universe because many legacy applications still evaluate it for SMTP delivery, but its primary pricing page was not accessible to the crawler during this audit.

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.

Against trial expiry notices, dunning, onboarding sequences, and per-tenant transactional mail, SMTP.com covers event stream, the suppressions API, and webhook coverage, and does not cover multi-tenant support and scheduling. Whether that gap matters depends on how central those are to the build.
