Swoosh is the go-to email library for Elixir with adapters for every major provider — Mailgun, SendGrid, SES, Postmark, and SMTP. Bamboo offers a similar composable approach. Premailex handles CSS inlining for email clients. gen_smtp lets you run your own SMTP server. All integrate cleanly with Phoenix and Oban for reliable delivery.
