Superhuman Alternative: Skip the Inbox Instead of Speeding It Up

What Superhuman does well

Superhuman is the best looking email client on the market and the keyboard shortcuts are real. Command K, J and K to move through threads, E to archive, H to mark done. After a week of practice you really do process mail two to three times faster. If you live in email and want to clear it faster, very few tools are this polished.

The Split Inbox, snippets, scheduled send, and follow up reminders are genuinely useful, and the team supports them with a hands on onboarding call that gets most people up to speed inside an hour. The Read Statuses feature, while controversial, is a real tool for sales and recruiting threads where timing matters.

The mobile app is fast, the search is fast, and the design is honest about what it is. Superhuman never pretends to do your email for you; it gives you a sharper tool to do it yourself. The AI features it has added recently, like Auto Summarize and Write with AI, are tucked into the existing flow rather than bolted on, which is the right call for an audience that already likes the way the app feels.

Where Sifta is different

Sifta is not an email client. There is no app to install, no Split Inbox to configure, no keyboard shortcuts to memorize. You connect Gmail or Outlook, give Sifta your phone number, and important mail starts arriving as iMessages within minutes.

The win is different. Superhuman shortens the time you spend in your inbox per session. Sifta cuts the number of sessions. You can go a full afternoon without opening email and still know about the one investor reply that needed you, because Sifta will text you about it.

Sifta also writes drafts. When a message clearly needs a reply, Sifta texts you a draft and waits for you to confirm. You can adjust the tone in plain language, like Make it warmer or Cut it in half, and Sifta rewrites and asks again before sending.

Superhuman is $30 per month and assumes you want a daily relationship with your inbox. Sifta is $49 per month and assumes you do not.

There is also a learning curve difference. Superhuman expects you to invest a real onboarding session, learn the shortcut grid, and rebuild your habits around Split Inbox. Sifta has no shortcuts, no labels, no setup wizard. You connect your account, verify your phone, and the next time an important email hits your inbox, you get a text. Most people are fully set up in under five minutes and never touch a settings page again.

Sifta also keeps quiet on purpose. You will not get pings for newsletters, receipts, calendar invites that already match your availability, or back and forth threads where you are only on CC. Superhuman shows you every one of those, just faster. Sifta hides them by default and only escalates when something genuinely changes.

Who should use Superhuman

Pick Superhuman if you enjoy reading and writing email and want the fastest, sharpest client to do it in. It is the right call for power users, busy executives with a chief of staff handling triage, and anyone who finds email energizing rather than draining.

Who should use Sifta

Pick Sifta if you would rather get a short text than open another app. It is built for founders, investors, recruiters, and operators who already feel they spend too much time in email and want most of that time back.
