How are you all keeping track of group emails?

I have 1,000 contacts to email. I send the email to the first 100 contacts. Then I go back to email the next 100 contacts. Now I'm stuck. How do I know which contacts I just emailed? I'm stuck here and must be missing something simple.

How does everyone else keep track of which contacts have already received an email?
