Mailman is a wrapper around the mighty (but rather low-level) gen_smtp, the popular Erlang SMTP library.

Which email library should I choose? Mailman vs. Bamboo vs. Swoosh

The Elixir ecosystem now offers a number of email libraries to choose from.

Mailman has been around the longest. As an Elixir wrapper around the battle-tested gen_smtp client, it is designed primarily with SMTP power users in mind. If you are interfacing directly with an SMTP relay, Mailman is for you.

If you instead work with a commercial email service like SendGrid or Mailgun, consider libraries like Bamboo and Swoosh, which come with clients for these services. Note that both of these libraries offer SMTP adapters as well.

Simple example

Emails are sent using the Mailman.deliver function. All you need is the email itself and a %Mailman.Context{} configuration struct:

context = %Mailman.Context{
  config: %Mailman.SmtpConfig{
      relay: "yourtdomain.com",
      username: "userkey-here",
      password: "passkey-here",
      port: 25,
      tls: :always,
      auth: :always,
  },
  composer: %Mailman.EexComposeConfig{}
}

email = %Mailman.Email{
  subject: "Hello Mailman!",
  from: "mailman@elixir.com",
  to: ["test1@tester123456.com"],
  cc: ["test2@tester1234.com", "abcd@defd.com"],
  bcc: ["1234@wsd.com"],
  data: [
    name: "Yo"
  ],
  text: "Hello! <%= name %> These are Unicode: qżźół",
  html: """
<html>
<body>
 <b>Hello! <%= name %></b> These are Unicode: qżźół
</body>
</html>
"""
}

Mailman.deliver(email, context)
