You may get items in your Send to Donorfy review list with strange email addresses or email addresses you do not recognise - see example below.

This can happen when you forward an email you have received to your Send to Donorfy email address - Donorfy examines the email to look for email addresses to use for matching to constituents and may find something that

1. Looks like an email address but is actually not 
2. Is a valid email that was included in the email but is not of interest to you e.g. noreply@somewhere.com

You should delete any items you don't need from the list
