When a donor tells you that they didn't receive the email receipt for a donation, there could be many reasons: an internet interruption, spam setting, or incorrect email address - just to name a few.
Here are a few steps you can take to help.
Verify that the email address is correct in the Transaction Reports record for one-time payments or in Recurring Payments for recurring transactions.
Ask the donor to check their spam folder.
There are too many service providers to address each one, but since Gmail is commonly used, we have prepared a detailed guide, Gmail: How To Find The Spam Folder that you can share with your donors.
Resend the email receipt.
