Deep Dive: Switching from Fastmail to Apple Mail
Trade-offs, installation & data architecture
What you trade away
Apple Mail is only a client, so it cannot replace Fastmail’s hosted mailbox, custom-domain delivery, aliases, server-side filtering, calendar, and contacts.
How to deploy Apple Mail
Preinstalled on macOS, iPhone, and iPad; add an IMAP, Exchange, iCloud, Google, or other supported mailbox
Where your data lives
Messages remain in the connected mail provider and are cached or indexed in the local Mail profile; local mailboxes can be exported as mbox files
Why fork Apple Mail instead of vibe-coding a Fastmail clone?
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Fastmail, build a clean client for an existing mailbox without running public mail infrastructure. The hard boundary is mail hosting, spam filtering, domains, calendars, contacts, deliverability, and support, plus mail infrastructure, integrations, and client polish.
