# Postmark Compatibility Issue

 * When sending emails via the Postmark Plugin, the following error is displayed
   on the front end:
 * “Failed to send your message. Please try later or contact the administrator by
   another method” – mapped to this error: **Sender’s message failed to send**
 * However, no errors are logged on the server. However, when I remove the use of
   Postmark, the email sends.
 * The changes I made that could have affected this is:
 * 1. An upgrade of WordPress to 4.5.2 from 4.4.2
 * 2. An upgrade of Contact Form 7 to 4.4.2
 * Also another issue noticed (I can save it for another ticket but will mention
   it here), is that the Mail2 option doesn’t work. It will send the mail2 option
   but not the intial email. In fact, sending 2 emails at once will not work either
   by using 2 email addresses.
 * Your product has been great so far, and this issue has only happened since the
   above upgrade. Going backwards with Contact Form 7 did not work, so the issue
   was probably introduced by a change in WordPress. However, if your plugin is 
   going to work with future versions of WordPress, you may be able to find a fix.
