Transactional email API
Every account now comes with a free mailbox — warmed automatically, no domain to buy. See how it works
Warmerly's transactional email API is one HTTP request, so there is no SDK to install. These guides give you the complete, working code for the frameworks developers ask about most, with idempotency and error handling included.
Every guide uses the same request, documented in the API reference. Warmerly is REST only today: no SMTP relay, webhooks, templates or attachments yet.
Create a free account, verify a sending domain and send a test. 5,000 emails a month free, no card.
