Email check for purchased tickets

What specific challenge or problem does this idea solve?

After I tried emailing those who had purchased tickets I got emails saying that certain emails could not be delivered. It would be amazing to know which emails were recorded incorrectly earlier so it could be corrected.

How should this work?

If a confirmation email can not be delivered to whoever purchased tickets it should flag something or send us a message to follow up with that ticket purchase.

Who will benefit (Admins, Staff, Students)?

Staff and families

How will this change impact your daily tasks or overall experience?

Simplify events and ticketing so we don't get so many requests right around the time of the show that they don't have tickets.
