ActiveCampaign Postmark for WordPress

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 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

There are two ways to tag a message.

1. 01Set an X-PM-Tag message header, i.e. array_push( $headers, ‘X-PM-Tag: PostmarkPluginTest’ ); where you are calling wp_mail().
2. 02Add a filter for ‘postmark_tag’ that hooks into a function that returns the tag you desire.

Using the postmark_tag filter will override a tag set via message headers.

Add a filter for ‘postmark_metadata’ that hooks into a function which returns the array of metadata you wish to attach to a message.

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.

You can optionally set the Postmark API Token, message stream, and default sending address by adding the following to your wp-config.php file:

`

define( ‘POSTMARK_API_KEY’, ” ); define( ‘POSTMARK_STREAM_NAME’, ‘stream-name’ ); define( ‘POSTMARK_SENDER_ADDRESS’, ‘from@example.com’ ); `

Setting any of these here will override what is set via the plugin’s UI.

There are a couple ways to resolve this issue.

1. 01Open the 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.
2. 02Access your WordPress site directory and open the wp-login.php file.

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.
