I got this message from my site
Howdy!
Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.
In this case, WordPress caught an error with one of your plugins, AcyMailing.
Also how do you delete all of the users, as I subscribe to many, I click all (box) and the bulk delete but it only does 5 at a time the ones display ( it only showed 5 users per page)
How do you only add say members and not subscribers from the WP site we have paid members and unpaid subscribers but only want newsletter to goto members onl,y too many to hand sort ,as your list does not show what they are.
