Who each one suits

Fastmail

  • People leaving free, ad-funded email for a paid private service
  • Using your own domain for personal or family addresses
  • Small businesses that want email without a full office suite

HEY

  • People ready to move to a new email address and a different inbox routine
  • Anyone who wants to approve senders before they can reach the inbox
  • Small teams that want email on their own domain with thread sharing

Worth knowing

Fastmail

  • There is no free plan. After the 30-day trial every account is paid, and Fastmail does not refund unused subscription time.
  • The Basic business plan has 6 GB per user and leaves out custom domains, Scheduled Send, Snooze and third-party mail apps.
  • Storage beyond the plan allowance is a paid add-on, up to 300 GB per user.
  • Listed prices are tax-exclusive.

HEY

  • HEY is its own email provider, not a client for Gmail or Outlook; existing mail history is not imported, only forwarded going forward.
  • IMAP and POP are not supported, so HEY works only in its own apps.
  • HEY for You is billed annually only, and HEY for Domains is billed monthly with no free trial.
  • There is no free plan.

Key features

Fastmail

Custom domains and extra addresses
Use domains you own for your addresses, buy one through Fastmail, or pick one of its free domains. Fastmail says each account can create hundreds of additional addresses.
Masked Email
Creates stand-in addresses so that sign-up forms and logins never see your real one. A Masked Email API lets password managers create them too.
Offline apps on every platform
Apps for Windows, macOS, Linux, iOS and Android, plus a browser app. Offline, you can read, draft and search mail and manage calendars and contacts.
Snooze, Scheduled Send and pinning
Snooze messages until they are needed, schedule sends for later, pin important messages to the top of the inbox and mute threads you do not want to follow.
Calendar and contacts
A built-in calendar with shared calendars and event invitations that can also display Google and iCloud calendars, and a contact list with VIP-only notifications.
Open protocols and import
Mail is reachable over JMAP, IMAP and POP, contacts over CardDAV and calendars over CalDAV. An import tool moves mail, calendars and contacts from another provider.

HEY

The Screener
First-time senders land in the Screener, where you approve or block them before any of their email can reach your Imbox.
Imbox, The Feed and Paper Trail
Mail from approved senders goes to the Imbox, newsletters are shown in a feed-style reader, and receipts and confirmations are filed in the Paper Trail.
Reply Later and Set Aside
Move emails that need an answer into a Reply Later pile and work through them in Focus & Reply. Set Aside keeps messages on hand for reference.
HEY Calendar
A calendar is included with HEY for You and HEY for Domains and lives in the same apps as email.
Spy pixel blocker
Blocks tracking pixels in incoming email and identifies the companies trying to track whether you opened a message.
Workflows and Collections
Workflows track an email through stages you define, and Collections bring several related threads together on one page.
