If you've tried sending email from a Cloudflare Worker, a Deno app, or a Bun server, you've probably hit the same wall I did: Nodemailer doesn't run there.
Nodemailer has been the default for ~15 years, and it's excellent — but it's built on Node's net/tls/stream built-ins. On the edge and on non-Node runtimes, those simply don't exist. You end up reaching for a provider's proprietary SDK per environment, or giving up on a unified API.
So I built sently — a runtime-agnostic email library that runs anywhere JavaScript runs.
