Your inbox isn't a lead list.
GateKeep blocks cold outreach from strangers automatically. If you've emailed someone before, they can always reach you. Everyone else has to earn it.
Free early access for the first 500. No spam, obviously.
Cold email became an industry. Your inbox became the product.
Agencies, offshore SDR farms, and "sales engagement platforms" have turned your email address into inventory. And nothing you do stops them.
Spam and unsolicited emails are sent every single day. The tools behind them advertise "unlimited sending" as a feature.
Inboxes one sequencer seat can blast before lunch, with mail-merge "personalization" and automated follow-ups that never quit.
Tools that let you decide who gets to reach you based on your actual relationship history. Until now.
Spam filters catch scams. They don't catch the "quick question," the "bumping this to the top," or the fourth follow-up from an agency you've never heard of. That's not spam to Google. It's spam to you.
Three steps. Then silence.
GateKeep works from a simple principle: your sent mail already knows who belongs in your inbox.
Connect Gmail
GateKeep scans your sent history and builds your whitelist automatically. Anyone you've ever emailed is in. No setup, no manual lists.
Set your rules
Decide what it takes for a stranger to reach you. Warm intro? Verified domain? Nothing at all? Your gate, your criteria.
Your inbox, your terms
Cold outreach gets stopped before you ever see it. The people who matter get through instantly, every time.
Built for people whose email address became a target.
Founders
You raised a round, and now every dev shop on earth has your email. Get back to building. GateKeep holds the door.
CEOs & executives
Your title is on a list being sold right now. Reclaim your mornings from pitches you never asked for and never will.
Anyone with a public inbox
Investors, operators, creators: if your address is guessable, it's being sequenced. GateKeep makes it yours again.
The cold email industry had its turn. Take your inbox back.
We're onboarding the waitlist in small batches: the first 500 get GateKeep free during beta. After that, the gate closes.
One email when it's your turn. That's it.
