Who each one suits

Boomerang

  • Gmail users who want scheduled sending and follow-up reminders
  • People who arrange meetings by email rather than a separate tool
  • Holding back incoming email to protect blocks of focus time

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

Boomerang

  • The free Basic plan allows 10 message credits a month, counted across Send Later, reminders, response tracking and read receipts.
  • Personal is limited to @gmail.com addresses; Google Workspace accounts need Pro or Premium.
  • The iPhone and Android apps are not part of the free Basic plan.
  • This entry covers Boomerang for Gmail, a browser extension. Boomerang for Outlook is a separate product with its own subscription.

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

Boomerang

Send Later
Write an email now and schedule it to send automatically, choosing the time from a calendar picker or by typing a phrase such as "next Monday".
Boomerang reminders
Archives a message and returns it to the inbox at the time you choose, marked unread, starred or placed at the top of the message list.
Response tracking
Reminds you to follow up if nobody replies to a sent message within a set time, or regardless. Read receipts and click tracking are also on every plan.
Meeting scheduling
Suggest Times, Bookable Schedule, Share Free/Busy and Meeting Poll let guests choose a slot from inside the email. Unlimited meetings need Pro or Premium.
Inbox Pause
Stops new email from reaching the inbox until you are ready for it, and can run on a schedule to deliver mail in batches or switch off after work hours.
Respondable
An assistant that uses artificial intelligence to help you write clearer, more actionable emails as you type. Its advanced machine learning features need Pro.

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.
