A bouncer for
your inbox.
Rythm adds a bouncer to your Gmail or Outlook. People you know get through. Everyone else waits. You decide what deserves your attention, and when.
Protecting inboxes since 2025.
Your inbox wasn't built to protect you.
Every year, the cost to send a million emails drops. Every year, the messages get harder to tell apart from real ones. Spam filters were built for a world where junk looked like junk. That world is already gone. Rythm doesn't try to outsmart them. It charges them.
Three steps to a protected inbox.
Keep your email. Add a bouncer. Take back control.
Build your guest list
Sign in with Gmail or Outlook. Rythm scans your existing contacts and builds your guest list automatically. People on the list always get through. No delays, no friction, nothing changes for them.
Unknown senders are sorted, not deleted
Emails from anyone not on your guest list are automatically filed into a separate folder. Nothing is deleted — think of it as a waiting room. Check it when you want, rescue anything you need, and that sender is added to your guest list going forward.
Strangers can pay to skip the line
You set a cover charge for unknown senders. It's small enough that a real person won't hesitate, but expensive enough that mass spam becomes impossible. Paid emails land in your inbox marked PAID. The money settles directly to your wallet.
What your bouncer does for you.
Rythm handles the hard parts invisibly. You just enjoy a cleaner, calmer inbox.
Strangers pay you, not us
When someone pays the cover charge, it settles directly to your personal wallet. Not to Rythm, not to an intermediary. We never hold your money. It's yours the moment it's sent.
Your mail stays your mail
Rythm checks who's at the door and looks for one thing: a proof. We scan incoming messages to detect a payment proof only, then immediately discard the contents. No email content is stored. No email content is shared.
Your guest list builds itself
Your guest list builds itself from your contacts and activity. Send or reply to someone? They're on the guest list so their response always gets through. Rescue a filtered email? That sender is added to your guest list too.
Nothing to switch
Rythm works with Gmail & Outlook. Your emails stay where they are. No new address, no migration, no learning curve.
A safety net for what you can't miss
Critical but rare senders, like the IRS, a court filing, or a legal settlement, are recognized automatically and always reach your inbox, even if they're not on your personal guest list. Think of it as a safety net for emails you can't afford to miss.
You set the price
Your cover charge, your call. Set it anywhere from a couple of cents to a few dollars. At just 4 cents, a real person won't think twice — but a spammer sending 100,000 emails? That's $4,000. The economics of mass outreach collapse the moment there's any cost at all.

What we believe
Your attention is valuable. It should be treated that way.
Your Venue, Your Rules
You decide who gets in and what it costs. You own your guest list. You set the cover charge. Rythm is the muscle that enforces your rules. We're the bouncer. You're the owner.
Silence is Golden
Your inbox wasn't built to protect you. It was built for anyone who wants your attention, and the noise is only getting louder. We believe you shouldn't have to sift through the junk. That burden belongs on the sender, not you. Your attention, your terms.
What Happens in Your Inbox Stays in Your Inbox
We believe your bouncer should have all muscle and no curiosity. Rythm knows your guest list, your price, and your rules. We don't store your messages, sell your data, or build a profile on you. Your messages are yours alone.
