 * The wordpress plugin is not compatible with any wordpress version, as I used 
   the latest one and the old one on both no plugin settings shown at backend.
 * Test your plugin with all wordpress versions before writing tested upto 5.5.3
   version.

 * Hi [@jordanrevell28](https://wordpress.org/support/users/jordanrevell28/),
 * Thanks for the review. As mentioned in the [support thread you created](https://wordpress.org/support/topic/compatibility-issues-35/),
   this plugin has been tested on WordPress v5.5.3 prior to updating the tested 
   up to version. We also have not received any other similar reports of compatibility
   issues with WordPress v4.0+.
 * Sometimes this can happen if you have a plugin installed that conflicts with 
   Postmark, such as another plugin that overrides wp_mail. I recommend checking
   for conflicting plugins and your WordPress instance’s error logs to see if you
   can spot the issue.
 * Please reach out to us at [support@postmarkapp.com](https://wordpress.org/support/topic/compatibility-issues-34/support@postmarkapp.com?output_format=md)
   if you have any questions or want to provide any additional information.
 * Thanks,
 * Patrick
