Hello everyone, I recently deployed Discourse on my own server, and while everything is generally running smoothly, I’ve encountered a significant issue. My Discourse instance is sending out an excessive number of email notifications to users, informing them of new content updates. As a result, some users are receiving hundreds of emails in a single day, which is quite concerning. I’ve checked the settings and confirmed that the email notification frequency seems to be normal, but I still can’t pinpoint the root cause. I would greatly appreciate any assistance or advice on how to resolve this issue. Here are some steps I’ve already taken: Reviewed the email notification settings and ensured that there are no options enabled for overly frequent notifications. Checked user notification preferences to confirm that they haven’t opted in for excessive email updates. Consulted Discourse’s official documentation and forums, but haven’t found a relevant solution. If anyone with experience could share insights on how to reduce the email sending frequency or any other configuration tips, I would be very grateful! Thank you for your help! Best regards

You can change “max emails per day per user” By default users get notifications only for topics that they are watching. Have you or they done something to watch a category that gets loud) lots of new posts? Are users watching some category that is getting many posts?

Another recent and similar experience here: [image] More then 3 million enqueued jobs show in sidekiq? How to I stop it generate the queue? Support One thing I noticed is that the sidekiq queue issue started right after I upgraded to 3.4.0.beta4-dev, the other instance I installed around the same time seems to have the issue too (confirming now) also looked at the ids, it seems the system is trying to send chat summary to every users thinking is it normal?

no, even I am just a freshman in the bbs. I received many many emails.

Could you tell me how to set this metric?

Search the system settings for that setting.

How are your categories notification set? If all categories are set to “Watching” then it will email in each topic creation and reply. Watch first post - only sends email on topic creation. Tracked - just keeps notification on site counts without email being sent When I first set up my server I mistakenly chose sine categories as Watching and had lots of emails being sent as a result.

could you tell me how can I set this categories notification?

If you haven’t changed defaults in Site Settings\User Preferences then this is not likely an issue that caused your mass emailing [The image shows a settings interface with options for selecting default topics that automatically unpin, categories that are watched, muted, or still get watched for the first post, as well as default categories that are not muted and a reset button for each category. (Captioned by AI)] Under the Admin.sidebar, all site settings, user preferences you can set a variety of defaults like you would in your own Preferences on your profile and have the apply to all users in the admin area. If you have created groups you can also set member defaults for category and tag notifications. Educating your members on notification types might also be an ideal. What Jay said though about limiting number of daily emails per user is your best option to have best control. Same area “All site settings” search term ‘max email’ it is under email section. But here is a SS for ease [The image displays the "Max email" settings window in Maximal, showing the maximum number of emails per day per user is set to 15, the maximum staged users per email is set to 10, and the maximum recipients per new group email is also set to 10.
