I have installed and tested Newsletter plugin. I sent last week my first bulletin with my last 10 posts. This week I scheduled it again to send latest posts, but the bulletin appeared with the same previous posts. What did I do wrong? I saw that if I edit the newsletter, it is refreshed, but if I only added five posts, the other five are repeated.
Do I have to use the premium “automated” feature? Is it going to repeat posts previously sent in my weekly newsletter?
