add a way to track contacts over time please!

[bethK3]

Hello,

Please add a way to track the # of contacts over time for certain lists (and the whole list). I am benchmarked on the growth of one particular list, and I want to be able to pull contact reports say of contact growth (or not growth) over a calendar year, or two quarters last year, or a fiscal year, or two fiscal years, or custom dates. I know I am not alone in this -- plenty of marketers have these benchmarks we are trying to meet, especially now that a lot of orgs/businesses are realizing that they own their email list and that's where the gold is. Please let us have insights into what's working! (And save us time in pulling these reports. I am doing this all manually right now and that is ridiculous in 2025.)
