OP's original issue had to do with changes to Gandi's included email service specifically.

Perhaps the title should indicate that Gandi is rugpulling email accounts from people who have prepaid for domain registrations.

They haven't told me I'm losing my mailbox yet but I'm on the lookout.

The free mailbox was honestly one of the biggest reasons I chose Gandi, and I would not mind paying for it at all - preferably not under duress though!
