I would email them around 1 time per week These can be informational posts and also your offers. Make sure that they are interesting and very targeted. Add in affiliate links about every 2 weeks or so. This should keep your subscribers up and prevent un subscribes
These are great questions. You’re so right that it’s important to build a relationship with your list. To answer your specific questions… this is what I do: 1) Provide quality content as well as getting them to know, like & trust you. Personally I like to use videos to warm up my list… but it’s important to just yourself 2) I usually email them 3-4 times a week. However I only email out a sales offer once every 3 emails or so. Also – important – with every sales offer I include a usefully tip & don’t just try to sell them something…. Again – this goes back to know, like & trust from my first point. I go over a lot of this in my list building course. PM me if you want more details. I hope this helps!
