How we grade them
| 3.0GPASaneBoxVery good | 2.4GPASuperhuman MailFair | |
|---|---|---|
| Value for money | CSnack is $6.99 a month or $58.99 a year, which sounds fine until you see it covers 1 email account and any 2 features. Lunch is $11.99 for 2 accounts and 6 features. Only Dinner has the lot, at $35.99 a month or $299.99 a year. That's a steep climb for filtering. | C$25 a month for an email app is a lot when Gmail is free. It can pay for itself if email is your job. For most people it won't. |
| Free plan and trial | CNo free plan. You get a 7-day free trial of any plan with no credit card required, then it's a paid subscription or nothing. We think a week is short for a filter that has to learn your habits. | FThere isn't one. No free plan, and the pricing page doesn't mention a trial, so you pay to find out. |
| Features | AIt learns from how you handle mail and moves the unimportant stuff to SaneLater, with a Daily Digest of what it filtered. SaneBlackHole keeps a sender out for good. Add snooze folders, reminders when a sent email gets no reply, and a do-not-disturb mode. For filtering, that's the full kit. | ASplit Inbox, a shortcut for everything, reminders, AI writing and summaries, shared threads and a built-in calendar. It's a lot of email app. |
| Ease of use | A4.6 from about 650 App Store ratings. There's no new app to learn: its folders simply show up in whichever email client or device you already use. | BQuick once the shortcuts sink in, and one reviewer says ten minutes did it. You do have to learn its way of doing things. |
| Platforms and integrations | BIt works with Gmail, Microsoft 365, iCloud, Yahoo, Fastmail and other IMAP or Exchange accounts, with a web account plus iPhone and Android companion apps. Those apps aren't email clients, though, and nothing beyond mail accounts is listed to connect to. | BMac, Windows, iPhone, Android and a Chrome extension for the web. Only for Gmail and Outlook accounts, though. |
| Best for | smarter filtering in the email app you already use | people who live in their inbox |
