A donor or registrant claims that they never received an e-mail.
Most likely the e-mail was sent but the recipient never got it. The most likely culprits are:
- entered e-mail address was wrong,
- it has gone into the spam folder,
- recipient gets many e-mails so the e-mail gets lost among the "noise,"
- e-mail system has put it in an unexpected category.
If this happens, it may be best to look at the e-mail that was sent and re-send it to the recipient. You can even send it to a different e-mail address, including your own.
