We are using NodeBB for Ukrainian expat community since 2017 https://forum.ukrexpat.com/

It is currently possible to disable all user email notifications, but it would be really useful to separate a digest email from other emails. Quite often forums are using paid services, such as mailgun, which have strict email sending limits, so it is quite easy to go over these limits when enabling email notifications (because all users want to subscribe to many topics). But digest is only sent daily, so it helps to avoid this issue because we will know exactly that every user will not receive more than 30 notification emails per month. But currently I don't see how it is possible to enable only emails for a digest, and disable it for other types of non-system notifications.

Yes, the last post on the forum was made 2 days ago. I just created a new post and vuala - it works and also the template is brand new. Looks like the the post statistics somehow was reset after upgrade, this is why it didn't pick up the topics created earlier this week. Thanks for explanation!

Thank you, I created a new issue on GitHub for this feature request https://github.com/NodeBB/NodeBB/issues/5644
