Elastic Email
Low-cost email API and SMTP relay with marketing features nearby.
Elastic Email offers both an Email API product for transactional sending and an Email Marketing product for campaigns. The API plan includes SMTP relay, templates, suppressions, tracking, inbound processing, webhooks, users, subaccounts, and custom rDNS on paid tiers. The free plan is primarily for testing because sending is limited.
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, Elastic Email covers every capability this audience leans on: multi-tenant support, event stream, the suppressions API, scheduling, and webhook coverage. The deciding factor becomes price and operational preference rather than feature gaps.
