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.
At an early stage the deciding factors are what the free tier actually covers, what the first paid invoice looks like, and how much of a founding engineer's week the setup costs. Feature depth that only matters at a million sends a month is noise until it is not.
Against a waitlist, a launch announcement, onboarding email, and the first transactional sends, Elastic Email covers every capability this audience leans on: developer experience, scheduling, SDK breadth, and webhook coverage. The deciding factor becomes price and operational preference rather than feature gaps.
