Hello! If a post has already been sent, it will not be included again in the same Post Notification email in Mailpoet. However, this only applies to the same Post Notification email. There is no built-in way to prevent a post from being sent again to the same subscriber across separate notification emails. Use case: -> We use Mailpoet to send "instant notifications": one based on authors; -> and a separate 'daily digest' based on post tag/category. If author A publishes also published a post in category A and a user is subscribed to both lists, they will receive the same post twice. 1) It would be great to be able to create and send one email notification post where the filters are dynamic and based on the email lists the user has subscribed to. 2) Alternatively, there should be an option to auto remove posts that the user has already seen in a different automated post notification email sent on the same day.
