## How To send a mail

Mail supports different types of backends to send email. So two steps are necessary to send an email.

- Step 1

  Create a new instance of a specific Mail-Backend with the factory()-method.

- Step 2

  Send the mail using send().

## The mailer backends

Mail supports three types of backends:

- `mail`

  Sends a mail using PHP's built-in mail() function.

- `sendmail`

  Sends a mail using a sendmail program.

- `smtp`

  Sends a mail directly connecting to a smtp server.
