Thoughts, 2025-07-07

account system

• data model
• user interface
• admin interface

invites and registration

• is this a different thing from the account system, or a feature of it?

payments and billing

• evaluate service provider (Helcim, Stripe)
• prototype integration with account system

primary account

• pays for things, 1:1 with a subscription
• one inbox

primary account

• aliases
• bring your own domain

secondary accounts / multiple inboxes

• is there a difference between an extra mailbox and a secondary account?
• primary account pays
  • subscription tiers? (1, 2, 10 mailboxes, etc.) (Fastmail “family plans”)
  • pay per user? (Fastmail “business plans”)
  • can secondary accounts have their own billing info?
• what admin controls does the primary account have?
  • edit aliases
  • grant secondary accounts ability to create their own aliases (Fastmail does this)
    • on service domains (crowmail.ca, crowmail.net)
    • on primary account custom domains
• can a secondary account be “upgraded”/moved to it's own primary account?
  • who can initiate?

Fastmail has the concept of a Team

• single accounts are still a part of their own Team
• a Team is what gets billed
• a Team has one or more Admins
  • Admins can edit billing info, add/remove users, etc.
