Were you aware that BVCMS has a Search Builder Condition that looks specifically for invalid email addresses ? These would be email addresses that are not in the correct format - missing the @ symbol, or the dot or having too many letters in the extension.
I spent a little time yesterday going through those records I found using this search on our church database. I was able to fix at least 95% of those addresses. Most were missing the .com after gmail, yahoo, etc. I feel better knowing that these people will now begin receiving our emails!
Of course, there were a few email addresses that I just deleted as there was not enough information there for me to figure out how to correct them.

PS When creating new records during an online registration or in the regular application (new members, guests, etc), you will be forced to use a a valid format. However, records that are edited, those that are part of a conversion, etc. may have these emails with invalid formats.
