SendPulse
Marketing suite with a generous transactional SMTP tier.
SendPulse spans marketing email, automation, chatbots, CRM, websites, and transactional SMTP. The transactional pricing is unusually generous for free SMTP volume, while paid plans add higher hourly throughput and dedicated IPs.
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, SendPulse covers event stream, the suppressions API, scheduling, and webhook coverage, and does not cover multi-tenant support. Whether that gap matters depends on how central those are to the build.
