Who each one suits

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

SaneBox

  • People who want to keep their current email app and add smarter filtering
  • Inboxes crowded with newsletters and notifications
  • Anyone who wants a reminder when a sent email gets no reply

Worth knowing

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.

SaneBox

  • There is no free plan; a paid subscription is needed once the free trial ends.
  • Snack covers 1 email account and 2 features, and Lunch covers 2 accounts and 6 features. Only Dinner includes everything.
  • It is not an email client: the iOS and Android apps are companions for digests, snoozing and blocking senders.
  • Prices here are the US App Store's in-app prices. SaneBox's own pricing page can show different figures and also sells a two-year term.

Key features

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.

SaneBox

SaneLater filtering
Analyzes how you handle email to judge what matters, then moves unimportant messages out of the inbox into a separate SaneLater folder.
SaneBlackHole
Send a sender to the BlackHole and their future messages are kept out of your inbox for good.
Daily Digest
A daily summary of the unimportant, unopened email that was filtered. Digests can also be processed in the iOS and Android companion apps.
Snooze and follow-up reminders
Snooze folders bring a message back to the inbox later, and SaneReminders flags sent emails that have not received a reply.
SaneDoNotDisturb
Holds incoming email during quiet time set aside for focused work and delivers it afterwards.
Works with your current email
Connects to Gmail, Microsoft 365, iCloud, Yahoo, Fastmail, IMAP and Exchange accounts, so its folders show up in whichever email client or device you use.
