+h5. Wire It Up So That the System Sends the Email When a User Signs Up
 
 There are three ways to achieve this. One is to send the email from the controller that sends the email, another is to put it in a +before_create+ callback in the user model, and the last one is to use an observer on the user model. Whether you use the second or third methods is up to you, but staying away from the first is recommended. Not because it's wrong, but because it keeps your controller clean, and keeps all logic related to the user model within the user model. This way, whichever way a user is created (from a web form, or from an API call, for example), we are guaranteed that the email will be sent.

 Notice how we call +deliver_welcome_email+? In Action Mailer we send emails by calling +deliver_&lt;method_name&gt;+. In UserMailer, we defined a method called +welcome_email+, and so we deliver the email by calling +deliver_welcome_email+. The next section will go through how Action Mailer achieves this.

 Hence, if the method name starts with +deliver_+ followed by any combination of lowercase letters or underscore, +method_missing+  calls +new+ on your mailer class (+UserMailer+ in our example above), sending the combination of lower case letters or underscore, along with the parameters. The resulting object is then sent the +deliver!+ method, which well... delivers it.

 Action Mailer will automatically send multipart emails if you have different templates for the same action. So, for our UserMailer example, if you have +welcome_email.text.plain.erb+ and +welcome_email.text.html.erb+ in +app/views/user_mailer+, Action Mailer will automatically send a multipart email with the HTML and text versions setup as different parts.
