If you’re still sending email with default SMTP, you’re blind to delivery problems! Postmark for WordPress enables sites of any size to deliver and track WordPress notification emails reliably, with minimal setup time and zero maintenance.
If you don’t already have a Postmark account, you can get one in minutes, sign up at https://postmarkapp.com.
- Upload postmark directory to your /wp-content/plugins directory or install from plugin marketplace
- Activate plugin in WordPress admin
- In WordPress admin, go to Settings then Postmark. You will then want to insert your Postmark details. If you don’t already have a Postmark account, get one at http://postmarkapp.com.

- Once everything is verified as working, check Send emails using Postmark and Save, to override
wp_mailto send using Postmark instead.
Postmark is a hosted service that expertly handles all delivery of transactional webapp and web site email. This includes welcome emails, password resets, comment notifications, and more. If you've ever installed WordPress and had issues with PHP's mail() function not working right, or your WordPress install sends comment notifications or password resets to spam, Postmark makes all of these problems vanish in seconds. Without Postmark, you may not even know you're having delivery problems. Find out in seconds by installing and configuring this plugin.
The Postmark for WordPress plugin overrides any usage of the wp_mail() function. Because of this, if any 3rd party code or plugins send mail directly using the PHP mail function, or any other method, we cannot override it. Please contact the makers of any offending plugins and let them know that they should use wp_mail() instead of unsupported mailing functions.
The Postmark service (and this plugin) are free to get started, for up to 100 emails a month. You can sign up at https://postmarkapp.com/. When you need to process more than 100 emails a month, Postmark offers monthly plans to fit your needs.
First, enable logging in Settings and check your send attempts for any errors returned by the Postmark API. These errors can let you know why the send attempts are failing. If you aren't seeing log entries for your send attempts, then the plugin or contact form generating the emails is likely not using wp_mail() and not compatible with this plugin.
If you are still unsure how to proceed, just send an email to [email protected] or tweet @postmarkapp for help. Be sure to include as much detail as possible.
Because we've been in this business for many years. We’ve been running an email marketing service, Newsberry, for five years. Through trial and error we already know what it takes to manage a large volume of email. We handle things like whitelisting, ISP throttling, reverse DNS, feedback loops, content scanning, and delivery monitoring to ensure your emails get to the inbox.
Most importantly, a great product requires great support and even better education. Our team is spread out across six time zones to offer fast support on everything from using Postmark to best practices on content and user engagement. A solid infrastructure only goes so far, that’s why improving our customer’s sending practices helps achieve incredible results.
This plugin detects HTML by checking the headers sent by other WordPress plugins. If a "text/html" content type isn't set then this plugin won't send the HTML to Postmark to be sent out only the plain text version of the email.
