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

SaneBox
- People who want to keep their current email app and add smarter filtering

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.
