Thanks for raising this, @Richie.
For some context, we added the feature to email deleted users earlier this year as it is a requirement for compliance with the Digital Services Act where all users need to be notified about changes to their account, including deletion.
To help admins who would rather not have this happen, we’re busy working on a feature that will allow individual email templates to be disabled so they never send to anyone. This will be able to be done per email from the email templates page in the admin.
We’ll circle back to this topic once that feature has been completed and merged.
