Recently changed my email in my forum details but still getting emails to the old addrress

Recently updated my forum email address to a new email address.
I’m still getting Paul’s posts and Copper emails to my old email address.

Don’t want to add my email addresses here for privacy reasons

The mailing lists for Paul’s Posts and Copper are are not linked to the forum; you signed up for these services separately. You need to update your preferences with each of them.

I suspect the best way to do this is to unsubscribe under the old email and resubscribe with the new.

Thanks Elk ……. it’s that long since I signed up for Paul’s posts and Copper magazine I forget where this was done.
Could you remind me please?
