For Emails to Work

Transactional Emails

Transactional emails are emails that are sent in relation to a transaction, such as a purchase (transaction) with purchase confirmation email sent.  

For transactional emails from the main plugin to work, the plugin checks the T-REX DNS server's records. The site domain must be added to the T-REX DNS settings in order for transactional emails to function. 

This means that you must provide to T-REX support, the domain that you are installing the plugin on (ie. yourdomain.com) so we can configure the T-REX DNS settings to ensure the transactional emails will work.

Mailer Plugin

The Mailer plugin uses Mandrill or the site's local server to send emails.

* For more information on Mandrill, visit the Mandrill website
