I have been involved with email marketing for a long time but I don't see myself as an expert yet and I am always seeking advice and opinions of other email marketers.
I was wondering how you maintain your lists (or do you).
For example, I check my lists every once in a while (once 3-4 months) and delete the inactive subscribers. Subscribers who did not open my last 10 or so emails. I have a good open rate and I don't send very frequently so 10 emails corresponds to a long period of time for my list. For whatever reason they are not opening my emails (they died, they don't use the email address anymore, they are not interested in my emails etc.) my personal opinion is that if someone did not open 10 or so consecutive emails, there is a very small chance they will open my future emails.
Would you consider deleting inactive subscribers a bad idea? How do you maintain your list if you do?
