I work in a medium sized business and we have several email audiences - basically, 3 overall audiences, with a few different subsets of each of those 3. We're in the education sector so you can think of the three like students/teachers/universities.
We send some operational messages and some commercial messages. Generally the commercial messaging only goes to one of the audiences.
However, we have over 20 send classifications. I was just looking for some perspective on how many send classifications is too many? This seems like an awful lot and I'm convinced we have some we don't use.
Would anyone mind explaining to me exactly how send classifications work? I find them a little confusing.
