- Upload postmark directory to your /wp-content/plugins directory or install from plugin marketplace

wp_mailto send using the ActiveCampaign Postmark API instead.
ActiveCampaign 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, ActiveCampaign Postmark makes all of these problems vanish in seconds. Without ActiveCampaign Postmark, you may not even know you're having delivery problems. Find out in seconds by installing and configuring this plugin.
The ActiveCampaign 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 ActiveCampaign Postmark API requires TLS v1.1 or v1.2 support. We recommend using TLS v1.2.
You can check your TLS v1.2 compatibility using this plugin. After installing the plugin, change the dropdown for 'Select API Endpoint' to How's My SSL? and run the test. If compatibility with TLS v1.2 is not detected, contact your server host or make the necessary upgrades to support TLS v1.1 or v1.2.
TLS 1.2 requires:
- PHP 5.5.19 or higher
- cURL 7.34.0 or higher
- OpenSSL 1.0.1 or higher
The ActiveCampaign 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, ActiveCampaign Postmark offers monthly plans to fit your needs.
First, enable logging in Settings and check your send attempts for any errors returned by the ActiveCampaign 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 ActiveCampaign 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 ActiveCampaign Postmark to be sent out only the plain text version of the email.
There are a couple ways to resolve this issue.
-
Open the ActiveCampaign Postmark plugin settings and uncheck Force HTML and click Save Changes. If the default WordPress password reset email is sent in Plain Text format, the link will render as expected.
-
Access your WordPress site directory and open the
wp-login.phpfile.
Change this line:
$message .= ‘<‘ . network_site_url(“wp-login.php?action=rp&key=$key&login=” . rawurlencode($user_login), ‘login’) . “>\r\n”;
Remove the brackets, so it becomes:
$message .= network_site_url(“wp-login.php?action=rp&key=$key&login=” . rawurlencode($user_login), ‘login’) . “\r\n”;
And save the changes to the file.
The plugin supports using the wp_mail_from_name filter for manually setting a name in the From header.
