Not another mail app
You keep Gmail. We’re not asking you to switch clients or providers.
Gmail · Consumer · Waitlist
Keep Gmail. Unknown senders verify before they reach you.
No new address. No forwarding. No new inbox. SendPermit sits on your Gmail with one filter and clear rules — so strangers can’t flood you for free.
- Works with Gmail
- Keeps your address
- Unknown senders held
- Legit senders can verify free
The problem
Sending email is effectively free — so abuse scales. You pay in attention, missed messages, and constant triage. SendPermit changes the economics for people who email you without an invitation.
Not sort-only
Filters and AI folders still let every message arrive. We add a sender-visible gate for unknowns.
Not enterprise IT
Built for individuals with public inboxes — podcasters, creators, founders — not org-wide gateways.
How it works
- 1Connect Gmail
OAuth with the minimum access needed to label and route mail.
- 2One filter, two outcomes
Incoming mail is processed: known senders flow to your Inbox; unknowns are held and notified.
- 3Verify or pay
Senders complete free verification or a small payment to deliver; then they’re allowlisted.
Exact latency and beta limits are covered in the FAQ. We ship honestly — see Security for what we access and store.
Why now
Inboxes are hitting painkiller-level failure modes: overload, lost legitimate mail, and senders you can’t stop. When providers strain under volume and automation, recipients need a lever that doesn’t require abandoning Gmail.
- Public addresses (shows, press, hiring) get scraped and hammered.
- Cold outreach scaled by tooling and AI increases noise past human triage.
- People are already paying with time — rules, blocklists, and inbox avoidance.
Who it’s for
Podcasters & hosts
Public pitch inboxes without drowning in cold email.
Creators & journalists
Protect attention without hiding your address.
Founders & operators
High-signal inbound only from people who mean it.
Privacy & security
Trust is binary with mail. We design for data minimization: routing decisions on metadata, with message bodies staying in Gmail. Details: Security & privacy.
Fair to legitimate senders
Unknown is not “guilty.” Real people can verify in seconds for free. Paid delivery is for instant path when appropriate — not a shakedown. If you received a notice from permit@sendpermit.com, see Verify your message.
