Sifta: The Superhuman Alternative That Handles Email Instead of Speeding It Up

A Superhuman alternative is any tool that helps busy professionals process email faster than the default Gmail or Outlook experience. Sifta takes a different approach: instead of giving you a faster inbox client to look at, Sifta reads every email for you and texts you only the ones that matter — directly in iMessage. You stop opening your inbox at all.

Superhuman is a beautiful, faster email client at $30/month. It still requires you to open it, read your inbox, and decide what matters. Sifta is $49/month and replaces that workflow entirely: connect your Gmail or Outlook, give Sifta your phone number, and the AI handles inbox triage on your behalf. Important messages arrive as iMessages with a 2-3 sentence summary. Newsletters, promotions, automated alerts, and CC noise are archived silently. Other Superhuman alternatives like SaneBox, Hey, Shortwave, and Spark all keep you inside an email interface — Sifta is the only one that gets you out of email entirely.

Sound Familiar?

You pay for Superhuman or are considering it, but you're realizing the bottleneck isn't how fast you can read email — it's how much time you spend in your inbox at all.

Faster keyboard shortcuts don't fix the fact that 90% of what arrives in your inbox doesn't need you, and you still have to look at it to know that.

You'd rather have someone (or something) handle your inbox than learn another email client's productivity system.

$30/month for a faster Gmail client feels expensive when the underlying problem — too much email — hasn't actually changed.

How Sifta Fixes This

✓

Sifta connects to your Gmail or Outlook via secure OAuth and runs continuously in the background — no app to open, no inbox to scroll, no shortcuts to memorize.

✓

An AI model reads every incoming email, classifies it for importance, and texts you a concise summary of only the messages that genuinely need your attention.

✓

Everything else — newsletters, receipts, automated notifications, low-priority threads — is archived silently. Your inbox stays clean without you ever opening it.

Frequently Asked Questions

How is Sifta different from Superhuman? +

Sifta is fundamentally different from Superhuman: Superhuman is a faster email client that you still have to open and read; Sifta is an AI agent that reads your inbox for you and texts you only the messages that matter. Superhuman speeds up email; Sifta removes it from your day.

Is Sifta cheaper than Superhuman? +

Sifta is $49/month versus Superhuman's $30/month, but Sifta replaces your inbox workflow entirely instead of just speeding it up. Most Sifta users save several hours per week, which makes the higher price point a clear win versus a faster email client you still have to manage.

Can I use Sifta and Superhuman together? +

Yes, Sifta works alongside any email client including Superhuman, Gmail, Outlook, Spark, or Hey. Sifta operates at the inbox level via OAuth, so whatever client you use to read or compose mail still works exactly as before.

What about SaneBox or Hey as alternatives? +

Sifta differs from SaneBox and Hey in one key way: those tools still require you to check your inbox to see what was filtered. SaneBox sorts mail into folders you have to open; Hey gives you a curated screener you have to review. Sifta is the only one that pushes the important stuff to your phone so you never have to open your inbox at all.

Does Sifta work with Outlook like Superhuman now does? +

Yes, Sifta fully supports Outlook in addition to Gmail. Connect your Microsoft 365 or Outlook.com account via secure OAuth and Sifta will monitor your inbox the same way it does for Gmail users — texting you only the emails that matter.

Stop speeding up your inbox. Stop opening it.
