When I use the AUTOMATED NEWSLETTERS feature I have all my old blogs getting generate. In the configuration I have the status date set today and it displays”There are 1 new posts ready for the next automated newsletter.”.
Hi, please open a support ticket for professional extensions. You can find the ticket page on top menu.
Probably in automated you set it to ignore the last sent day and process all the posts. Pay attention: the theme preview is just a preview and uses even old posts, you should look at the newsletter preview.
