1. Promoting two products with just affiliate links inside my weight loss followup series.
2. Promote more than two products in the followup emails. (if yes then how many?)
3. Have separate promotional emails between the followup emails.
Also, how many subscribers are required to tell that you have a successful converting list and in that case what will be the accepted conversions rate?
All suggestions are welcomed and people experienced in weight loss niche are most welcomed to share their opinions.
