Yes, those are generally correct. I did an analysis with our intern this summer and it was a bit hard, but it felt largely correct.
- Total # who Unsubscribed from Email on Day X (yes, you can only go back 90 days unless you opt out with Support).
- Total # who are Unsubscribed on Day X AND who Was Sent Email at least 2x
- Total # who are unsubscribed on Day X and who Was Sent Email at Least 1x
Since we can't say "Show me all who unsubscribed but only received ONE email" we have to do some math as we build the columns. We ended up doing 2 months of data, no weekends.
I'm not saying this is perfect, but we were able to show that sending more than one email per day did increase unsub rate for those who got more than 1 email that day. If you're using Comms limits as intended, this is less of an issue.
thanks Josh. We have com limits (1 day or 3 a week) but sending 1-2 emails a week may be too much for some regions. Ideally I would like to have data to prove my point
