Hi everyone, A large Discourse forum is experiencing an issue where digest emails (activity summary emails) are not being delivered to all eligible users as expected. Issue Details: I understand that digest emails are sent only to inactive users, but based on our settings, there should still be m…

[image] emonunix: To test this, we set the digest frequency to 30 minutes, ensured a new post was made, and still, no digest emails were sent to eligible users. Quick question, did you retroactively change this setting for all users? Because as far as I know, once it’s set at account creation…

Yes when I checked mine and some random users profile I found that the settings reflected there.

Thanks @Bas , we did update it to 30, and you can apply it retroactively—the system gives a message confirming that user records are being updated when making this change. <a class="lightbox" href="https://d11a6trkgmumsb.cloudfront.net/original/4X/8/2/f/82f83fd5482457065a37c682cca5c8ce2432e68e.png" data-download-href="/uploads/short-url/iGBWsDxFZLoVhqK2zStiSRXWnqC.png?dl=1" title="The image displays a confirmation dialogue asking if the user would like to change the default email digest frequency for 34,063,500 users historically, providing options to apply the change to existing users only or moving forward with the change.

Have you ch checked a few of the accounts not receiving to see if they have categories &/or tags muted? I believe if you have it muted th digest will not include topics. Otherwise the team is likely ty best resource. Another the ng with your mail server did you add dkim DNS record to your domain?…

Thanks @Heliosurge to be clear, the emails are not sent at all, so it’s not a question of if they are seen or blocked, or delivered to spam - discourse is not processing them in the first place. Here is a screenshot of the activity the last few days: Bear in mind this should be something like 90 di…

Okay but the other component is to also check a member’s preference ls in tags and categories. It is possible they might have things muted Another thing that a team member would beat to answer is if a member uses the unsubscribe in email link if it visibly changes things in the user preferences. T…

@Heliosurge sorry to answer your question. Sure there could be a few users that have settings that prevent them from getting the digest. We have a number of demo users on the site where we are controlling the settings and have verified (we think) that things should be delivered. So I don’t think it’…

[image] Jacob_Peebles: One thing that is odd, today I noticed that when I visit the site the ‘last visit’ line is very old, like 9 days, but I visit everyday - so that is not accurate. Could that logic also be related to what discourse is considering as the date to send the digest? I have no ide…

Thanks @Heliosurge As @Jacob_Peebles is visiting the site frequently above ____ last visit ____ line he should see very new posts only, like 5/10 minutes ago or 1/2 hours ago. We couldn’t figure it out why discourse is showing 8/9 days old post above last visit. I checked it from my account, I di…

Really not sure from here. As an admin were often the last ones to become aware of an issue You said your last visit info seems correct while @Jacob_Peebles last visit is not updating correctly? Wonder how many other users are having similar. Jacob is your account receiving digest emails? Now g…
