Testing Mail Delivery

Testing with Mail-tester.com

Mail-tester.com provides an email address for you to send email for testing purposes.  Once mail-tester receives the message, it will evaluate different aspects of the message from its content to the sending mail server.   Once completed, a report is generated with a score compiled from different categories.  The score ranges from 0 to 10, with 10 being the best score and least likely to have anti-spam issues.
