The Best Email Assistant for Founders Who Can't Afford to Miss What Matters

As a founder, your inbox is a battlefield. Investor updates compete with customer complaints, recruiting threads pile on top of partnership requests, and somewhere in the middle is a time-sensitive email you won't find until it's too late. The best email assistant for founders doesn't ask you to organize more — it organizes for you and delivers the signal directly to your phone.

Sound Familiar?

Investor emails sit unread for hours because they land between Stripe notifications and team CC threads you don't need to be on.

You've missed a customer escalation that could have been handled in minutes — instead it became a churned account because the email was buried.

Recruiting candidates go cold because their replies get lost in the same inbox as newsletter subscriptions and SaaS receipts.

How Sifta Fixes This

✓

Sifta connects to your Gmail or Outlook inbox and learns who matters to your business — investors, key customers, recruiting candidates, co-founders — and makes sure their emails reach you instantly.

✓

When a high-priority email lands, you get an iMessage with a concise summary: who sent it, what they need, and whether it's urgent. No app to open.

✓

Everything else — automated notifications, CC threads, newsletters — is silently archived so your inbox stays clean and your attention stays on building.

Frequently Asked Questions

How does Sifta know which emails matter to a founder? +

During setup, you tell Sifta about your key relationships — investors, customers, candidates, advisors. Sifta then learns from your behavior: who you reply to, what you open first, and what patterns signal importance. Over time, it gets sharper without additional configuration.

Can Sifta handle multiple inboxes for different ventures? +

Currently Sifta supports one Gmail or Outlook account per user. Multi-inbox support is on the roadmap and designed for founders juggling multiple ventures or roles.

Will this work if I use Superhuman or another email client? +

Yes. Sifta connects directly to your Gmail or Outlook account via OAuth — it doesn't matter what client you use to read email. Sifta works at the inbox level, not the client level.

Is Sifta better than just setting up Gmail filters? +

Gmail filters are static rules — they break as your contacts and priorities change. Sifta uses AI that adapts to your behavior. It also delivers summaries to your phone, which filters can't do.
