Client Libraries

There are a number of client libraries available to help send e-mail using the Postal platform.

• Ruby
• Rails
• Ruby (mail gem)
• PHP
• Node
• Java

All of these libraries will make use of the API rather than using any SMTP protocol - this is considered to be best approach for delivering your messages.

If your framework makes use of SMTP, you do not need a client library however you will also miss out on some of Postals functionality.
