Messages

All messages sent from the system will be listed here including any draft messages. Clicking on a draft message will allow you to continue editing it. Clicking on the columns will allow you to sort the messages by their type, addressee, Subject (alphabetically), status or date/time they were sent.  

Clicking on a Sent message will show you a copy of the email content plus some delivery information. 

Below the email will be the list of recipients which will include date and time stamps (if applicable) of when the email was sent, delivered, opened and if the email contained a link, where this link has been clicked.  

Apple's Mail Privacy Protection (MPP) service downloads emails to its own servers, which can set the status to "Opened" irregardless of whether this was opened by recipients. This could falsely inflate your email opens counter.
