Primary domain name. You pay for the inbox, not the domain.
replyMaybe I am misunderstanding but I don't think this is true. Indeed you pay for the inbox, but it's not the primary domain. You can reply from any of the email addresses you created (which doesn't cost extra) and it automatically sets the FROM to be the email it was received on
replyIf you have Fastmail configured to send from that domain as well, it will automatically reply from the same address the email was sent to. You can pick which address to send from, of those you have set up.
replyThat’s great. Thank you.
