Who each one suits
Mailstrom
- Clearing thousands of old messages out of a neglected inbox
- People who want to choose what goes themselves instead of relying on AI sorting

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
Mailstrom
- It runs in the browser only; the site lists no mobile or desktop apps.
- The free trial is a one-time snapshot of up to 5,000 messages, and only 25% of them can be deleted, archived or moved.
- It works over IMAP, so POP-only accounts and Exchange servers without IMAP enabled cannot be connected.
- Basic is capped at 1 email account and 10,000 emails, and the FAQ says folders other than the inbox cannot be organized yet.
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
Mailstrom
- Bundles of related mail
- Groups inbox messages by sender, subject, date and size so that tens, hundreds or thousands of them can be deleted, archived or moved to a folder in one action.
- Unsubscribe
- From the Mailing Lists tab, Unsubscribe sends a request email to the list owner. If the list gives no unsubscribe address, its web page opens in a new tab instead.
- Block
- Removes the selected messages and creates a rule that keeps future mail from the same sender, mailing list or subject out of the inbox. Available to subscribers.
- Chill and Expire
- Chill takes messages out of the inbox and returns them on a date you choose. Expire removes mail from a sender or mailing list after a set period. Both need a subscription.
- Automatic move rules
- A move can be saved as a rule, so future messages that match a sender or subject are filed into the chosen folder as they arrive. Subscribers' mail is loaded continuously.
- Undo and task history
- Actions are carried out by your email service and are not permanent: deleted mail goes to its trash, and an Undo feature reverses any command from the task list.
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.
