Swoosh is an Elixir library for composing, delivering, and testing emails. It provides a unified mailer API with adapters for popular providers like SendGrid, Mailgun, Mandrill, Postmark, and plain SMTP.

Use cases

  • send transactional emails from a Phoenix app
  • compose HTML and plain-text emails in Elixir
  • integrate SendGrid or Mailgun for email delivery
  • test email sending in an Elixir application
  • send emails over SMTP
  • build a mailer module with swappable delivery adapters

When to choose

  • you are building an Elixir or Phoenix application that needs to send email
  • you want a consistent API across multiple email providers with easy adapter switching
  • you need first-class test support for emails in your test suite

When to avoid

  • your project is not on the Elixir/Erlang ecosystem
  • you need a full self-hosted mail server rather than a client library for sending email
  • you require advanced inbound email parsing or campaign management features
