How can I know how many individual emails or subscribers I have in my audience?
Are you referring to the number of active contacts within a group? If so just go to your audience page and it shows them there.
I mean my total audience. I have several groups and some subscribers are in both. If I add the total of both groups it would tell me I have more subscribers than I actually do.
Ah gotcha, click on view all contacts in the top right corner on your audience page.
It will then give you something like this....
That worked perfectly. Thanks!
