While MightyBox servers are capable of sending mail from your WordPress environment, you’ll often find that delivery rates of messages sent in this manner are far from optimal. For a variety of technical and logistical reasons, our servers are simply not designed for sending mail.
Instead, we recommend using a transactional email delivery service such as Postmark. Postmark provides best-in-class email delivery, the ability to set up multiple client accounts (“servers”) under a single agency account, and a handy WP plugin to easily enable transactional email delivery across your site.
