How to Set Up WordPress SMTP With Postmark

by Shahzad Saeed on Mar 16, 2017

Are you not receiving email notifications from your WordPress contact forms? If you’re looking for an easy and reliable method to ensure email deliverability, using the Postmark plugin to set up Simple Mail Transfer Protocol (SMTP) on your site is the best bet. In this post, we’ll show you how to set up WordPress SMTP with Postmark.

Reasons for Not Receiving Notifications

WordPress uses the PHP mail function to send emails that are generated by a contact form plugin like WPForms. Many WordPress hosting servers are not configured to use the PHP mail function.

That means that your WordPress emails, including the WPForms notifications, won’t even make into the spam folder.

That’s why we recommend using SMTP to send emails from WordPress instead of using the default PHP mail function. SMTP (Simple Mail Transfer Protocol) is an industry standard way to send emails that use proper authentication method to ensure email deliverability.

Why Postmark
