Why people look past Superhuman
Superhuman Mail is a separate email client. You sign in with a Google or Microsoft account and read, triage, and send mail in its own apps, with keyboard shortcuts, Split Inbox, AI labels, and AI drafts. (Grammarly bought Superhuman in July 2025 and renamed itself Superhuman that October; the email app is now called Superhuman Mail.) Four reasons for leaving come up again and again in its reviews and its own fine print. If you're only weighing the two, read our SaneBox vs Superhuman comparison.
The first is price. Mail Starter costs $30 per member a month billed monthly, or $25 a month billed annually ($300 a year). Business is $40 a month, or $33 billed annually. There is no free Mail plan, Superhuman doesn't publish a standard free trial, and its Terms of Service say payments are non-refundable (a help article does offer to refund the unused part of an annual plan on request). Even happy reviewers mention the cost.
“It is a bit expensive considering it is basically a front-end for Gmail.”Avinash S., G2, August 2026
“The price is hard to ignore - it's several times what most email tools cost, and if you don't live in your inbox, you probably won't get your money's worth.”Shai D., G2, July 2026
The second is providers. Superhuman's help center says it supports only Gmail and Microsoft 365 hosted accounts. iCloud, Yahoo, Fastmail, and other IMAP mailboxes can't be added, and there is no unified inbox across the accounts you do add.
“the lack of a unified inbox across multiple accounts can slow things down”Igor S., G2, August 2026
The third is AI training. Superhuman's privacy policy (effective July 6, 2026) says it uses the information it collects to train its own AI models, and that you decide whether your content is used through training controls in your account settings. Its plans table lists training as opt-out on Business and lower plans, and off by default only on Enterprise. If that is your only objection, switching the setting off is simpler than switching apps.
The fourth is the switch itself. To use Superhuman you move your whole email routine into its apps, and the speed comes from learning its shortcuts. Reviewers who love it say the first stretch is slower.
“the first week or two of forcing yourself onto shortcuts is genuinely slower before it becomes faster.”Shai D., G2, July 2026
Superhuman's Trustpilot page is unclaimed and small: 12 reviews from April 2024 to September 2026, all unprompted, averaging 1.5. Five of them complain about billing or cancelling, and four say it sent emails or added ads they didn't ask for. That is too few reviews to stand for all its users, but the themes are consistent.
“Cannot cancel subscrption by myself.”Philippe Branche, Trustpilot, February 2026
Superhuman alternatives matched to your reason for leaving
| Compared on | Best alternative | Check before switching |
|---|---|---|
| $30 a month is too much | SaneBox: Snack $9.49/mo or $65/yr; Lunch $15.99/mo for 2 accounts | It sorts mail; it isn't an email client, so no keyboard triage or built-in AI writing |
| You want to keep Apple Mail, Outlook, or Gmail's own app | SaneBox: its folders appear in any app | Takes a few weeks of moving misfiled mail to train |
| You use iCloud, Yahoo, Fastmail, or another IMAP host | SaneBox, Clean Email, or Leave Me Alone | None of them replaces your email app |
| You don't want an AI client trained on your mail | SaneBox: says it sorts on headers and doesn't store your email | Superhuman lets you switch training off in settings, so staying is an option too |
| You want an AI email client, for less | Shortwave: free plan; Pro $18/seat/mo | Gmail and Google Workspace only; AI filters start at $30/seat/mo |
| You mostly want fewer newsletters | Leave Me Alone ($9/mo) or Clean Email ($9.99/mo or $29.99/yr) | They clean up and unsubscribe; they don't rank new mail by importance |

The 4 best Superhuman alternatives
SaneBox
Best for keeping your current email appSaneBox works on your mail server and sorts new mail into ordinary folders (SaneLater, SaneNews, SaneBlackHole) that show up in whatever app you already use, with Gmail, Microsoft 365, iCloud, Yahoo, Fastmail, or any IMAP account. Snack costs $9.49 a month or $65 a year for one account and two features; Lunch is $15.99 a month for two accounts. In our pull of each product's 50 most recent G2 reviews, SaneBox averaged 4.76 with none marked incentivized, and Superhuman averaged 4.71 with 42 of 50 incentivized. It isn't an email client: there are no keyboard shortcuts for triage and no built-in AI writing (its AI reply drafts are a beta you request from support), and it needs a few weeks of you moving misfiled mail before its sorting settles.
Full SaneBox vs Superhuman comparison →Shortwave
Best AI email client with a free plan (Gmail only)The closest like-for-like swap: a separate AI email client with inbox splits, bundles, AI search and writing, snooze, and reminders, on iOS, Android, Mac, Windows, and the web. It has a free plan (90 days of search history, no AI filters, and a 'Sent with Shortwave' signature), and Pro costs $18 per seat a month, billed monthly only. It works only with Gmail and Google Workspace; Microsoft 365 and Exchange aren't supported. AI filters, the nearest match to Superhuman's Auto Labels, start on the Business plan at $30 per seat a month. Shortwave refunds a payment on request within 14 days. Of its 50 most recent G2 reviews, 47 are marked incentivized, and the newest is from September 2025.
Superhuman vs Shortwave compared →Clean Email
Best for clearing clutter on a budgetIf you mainly paid Superhuman to get through clutter, Clean Email groups old mail by sender, size, and type so you can delete, archive, or unsubscribe in bulk, then applies your rules to new mail. It works with any provider, including iCloud and other IMAP accounts, and the changes show up in your own email app. One account costs $9.99 a month or $29.99 a year, every plan includes every feature, and a free plan cleans up to 1,000 messages. It doesn't rank new mail by importance, and its terms make payments non-refundable apart from narrow exceptions.
SaneBox vs Clean Email →Leave Me Alone
Best for unsubscribing for realLeave Me Alone unsubscribes you from mailing lists on its servers, then adds Rollups (digests), a Screener for new senders, and a Spam Blocker. It supports Gmail, Microsoft accounts including Office 365, Yahoo, iCloud, AOL, Fastmail, and any IMAP mailbox. Ten unsubscribes are free with no card; after that it's $9 a month for four accounts, $16 a month for unlimited accounts, or a one-off $19 Seven Day Pass, with a 14-day money-back guarantee. It has no iOS app yet, and it doesn't sort mail by importance.

The like-for-like case for SaneBox over Superhuman
SaneBox answers three of the four reasons above. It costs about a third of Superhuman's monthly price for one account, it works with any provider, and you keep the email app you have. Because it files mail into ordinary server folders, the sorting shows up on every device where you read that account.
On reviews, compared like for like: in our pull of the 50 most recent G2 reviews of each (October 1, 2026), SaneBox averaged 4.76 (June to September 2026) with none marked incentivized, and Superhuman averaged 4.71 (March to September 2026) with 42 of 50 incentivized. On Trustpilot, 49 of SaneBox's 50 most recent reviews were unprompted and averaged 4.86; all 12 of Superhuman's were unprompted and averaged 1.5, a small sample. On the App Store the two are level at 4.6 (SaneBox across 648 ratings for its companion app, Superhuman across 3.7K).
“It works with any email client, setup takes minutes, and it just gets better over time.”Tom B., Capterra, May 2026
The trade-off is training. SaneBox learns from what you open, answer, and move, so the first weeks need attention, and some long-time users still check its folders.
“The AI seems to need a bit more training than I'd like, requiring me to still continue checking folders to ensure it didn't miss anything.”Leila B., G2, December 2025
The 7-day trial covers every feature and up to four accounts and doesn't ask for a card. See the SaneBox plans and prices or read what the free trial includes.
When to stay with Superhuman
Stay if you live in your inbox and the shortcuts are already muscle memory. Superhuman offers keyboard-first triage, AI drafts in your own voice, read statuses, shared conversations and comments for teams, and calendar booking from the inbox, on Mac, Windows, the web, iOS, and Android. The filters and cleanup tools above don't try to do any of that, and Shortwave, the one client on the list, doesn't support Microsoft 365. Its recent G2 reviews are mostly positive, even when they mention the price.
“Obviously the cost is high, but I still consider it worthwhile because of the benefits.”Mat B., G2, August 2026
“Split Inbox is the feature I'd miss most if I switched away”Shai D., G2, July 2026
If you like Superhuman's interface and only miss sorting that works across providers, you can add SaneBox to it instead of replacing it.
Other ways to leave Superhuman
The cheapest option is going back to Gmail or Outlook on their own. Both have built-in filters, rules, and snooze, and they cost nothing extra. You lose Superhuman's AI and shortcuts, and the rules are yours to write and maintain. Some people who tried Superhuman preferred where they started.
“Gmail in Chrome, which I wanted to replace, is much better”Sebastian Zontek, Trustpilot, August 2026
We left Unroll.Me off this list. It is free, but it is owned by NielsenIQ and funded by using data from your commercial emails in products sold to companies, including data brokers. If privacy is part of why you're leaving Superhuman, that trade goes the wrong way. Our SaneBox vs Unroll.Me comparison has the details, and the best email management tools roundup ranks all six.
