+### Plain-text
+By default, plain-text versions are automatically created from your html template and included in the final email. It's strongly advises to leave this option on, as it greatly reduces your emails' Spam score and the chance that your emails will end up in Spam folder of users. However, if you want to override this behaviour simply at this to `Mailer.init()`:
+
+```coffeescript
+Mailer.init(
+  settings:
+    plainText: false
+)
+```
