 * Hi [@rebrush2](https://wordpress.org/support/users/rebrush2/),
 * Thanks for reaching out!
 * In most cases, you may experience the error “data not accepted” because of the
   following reasons.
 * **1)** You have authenticated the WP Mail SMTP plugin using one email address(
   info@example.com) but you’re trying to send an email using a different email 
   address (support@example.com).
 * **2)** Your email provider is not allowing you to use a different “reply-to” 
   email. In that case, you need to use the same WP Mail SMTP authenticated email
   as your “reply-to” email.
 * **3)** You’re trying to send an email notification with an attachment, but you
   have exceeded the attachment size limitation of your email provider or the file
   type is not allowed.
 * I hope this helps to troubleshoot your issue further. Thanks!
