A member of my community asked if they could have email notifications go to a new address rather than the one they use for their Discourse account. Can they do this or can we do this as admin?
סיכום מבוסס בינה מלאכותית
A community member requested to receive email notifications at a different address than their Discourse account email. pfaffman suggested changing the account email or using email filters to forward notifications, noting this would be handled within the user’s email service (e.g., Gmail). David_Kwan clarified the use case: users sign in with school emails but want notifications sent elsewhere. codinghorror confirmed that, at the time, users could not keep their current account email while designating a separate address for notifications. pfaffman humorously noted this might violate school policies, and confirmed filters would need to be set up in the user’s email client—if not blocked by the domain administrator. Later, codinghorror updated that Discourse now supports multiple email addresses per user, but no option exists to assign special treatment (like notifications) to one specific address over another. The core limitation remains: notifications are tied to the primary account email, and users must rely on external forwarding if they want them sent elsewhere.
They can change their address to the “new” address. If they want some Discourse mail to go to one address and other discourse mail to go to another address, then they can create a filter and forward the notifications to the other account.
How can they do this? Can they keep their current email associated with their Discourse account and provide a new address for email notifications to be sent to?
They want all email notifications sent to a new address. The use case is that they sign into our Discourse with their school email, but want notifications sent to a separate email address. I am guessing that what you suggest here would happen within their email service (Ex: gmail), right?
This is not possible at the current time.
Sounds like exactly what the school doesn’t want them to do. 
(In a former life I did educational technology research in schools, so I was once familiar with such rules in several districts.)
Right. They’d set up a filter in their school email to forward the notifications to the other address . . . if whoever manages the domain hasn’t disabled that feature.
Multiple email addresses per user are now supported in Discourse, but you can’t pick one email address to get special treatment or anything.
