Why not, if they are still logged in? What happens when they go to Special:Preferences#mw-prefsection-personal-email ?

If they're still logged in, the best way would probably to post the request on-wiki, ideally include the email in the request, so there's no doubt in the request being valid.

That requires passing "You must log in again to verify that you are Martin Urbanec." dialog, which requires their password.

I'll get them to do that and make sure the diff is posted here.

Would it also be possible for the diff to be deleted once the email has been added to the account?

Mentioned in SAL (#wikimedia-operations) [2019-06-18T12:13:39Z] <Urbanecm> Assigned an email address to Eritha@enwiki per user request (T223960)

Regarding diff deletion, an enwiki admin is required. I've requested a revdel via IRC.

Thank you!
