Hi, I am about to do a mail-out campaign and i am going to include the 'ID' on the envelope so i can remove all the returned mail from our database. Once i have all the returned mail, i will have all the information put into a spreadsheet.
My question is; once i have that spreadsheet with the unique 'ID's', how can i mass remove all those contacts/targets from my database?
I am using Sugar Professional 7.6.
Thanks in advance.
