Are you asking about
:
- People you send email to (your address book contacts)
- Your Identities (addresses you can use in the Compose screen to send from)
- Your aliases (addresses you use to receive email at Fastmail domains or custom domains)
I don't understand the comment about
service level of each email address (basic, professional, etc.). Do you have a commercial account with many user accounts, and you want to export a list of these Fastmail user accounts? The "email address" would then be the
login address. If so, I can't help you, since I only have single user accounts.
