Ah ok thanks Gav that makes sense as some replies aren’t generating emails and some are given a bit of time old posts will disappear and it will stop sending them . Thanks ?Update on email notifications on thread replies etc. If you turn email off in preferences that setting only takes affect for future threads you watch.
Any threads you currently watch you will have to unwatch to have no notifications on site or email. If you still want on site alerts then you need to unwatch and them watch after you have removed the email preferences in your account settings.
