It has happened that we need to look up an email address but don't remember the entire address, here is a way to search for it in the Desktop application.
From your Donors screen, please click the Filter Icon (1). From the Donor Table (2) please scroll down till you find "E-Mail address (all or part)" click on Set Filter (3)
Once you've clicked on Set filter, the "word(s) to find in email field" box will appear". Please enter (1) the information desired (in this example we are looking for GMAIL addresses) and click on Apply (2)
Here you will notice that your search of GMAIL addresses has resulted in 12 donors.
