Fastmail: polished individual email with calendar, $5/user/mo

SHIPMAIL: team email with shared inbox, $4/mo flat for 3 mailboxes

Rust-based mail engine, independently audited by Radically Open Security. Open protocols, no lock-in.

When SHIPMAIL is the better choice

SHIPMAIL is the better choice when the team collaborates on shared addresses. If support@, hello@, or billing@ need to be managed by more than one person, Fastmail does not offer that. SHIPMAIL builds shared inbox into the product.

Flat pricing also helps teams that have more mailboxes than people. Adding a role address on SHIPMAIL does not increase the bill. On Fastmail, every mailbox is another seat.

When Fastmail is still the better choice

Fastmail is the better choice for individuals who want a fast, private email experience with a polished interface. Search is excellent, the keyboard shortcuts are well thought out, and Fastmail has a 25-year track record of reliability.

If the team does not need shared inboxes and everyone works from their own private mailbox, Fastmail is a premium individual email host that earns its price.

Verdict

For teams, SHIPMAIL. For solo users, Fastmail. The deciding factor is whether shared inbox collaboration is part of the daily workflow.
