Inbox attention paywall

Make cold email
pay for itself.

Threshold puts a paywall on your inbox. Cold senders contribute to reach you — to your charity, to your bank, or both. You only see the ones with skin in the game.

Only cold senders see the paywall — real correspondence threads to you normally. Learn more.

Thanks for reaching out.

I'm filtering cold email through Threshold. To get on my radar, please contribute to my charity:
Bump — just be on my radar$25
Read and respond thoughtfully$100
15-minute call$500
Payment held in escrow. Refunded automatically if I don't engage in 21 days. 100% of proceeds donated to Build Up.
How it works

Three steps. Then your inbox runs itself.

01

Connect your Gmail

One Google sign-in. Threshold watches inbound mail in real time and classifies cold pitches with Claude.

02

Set your prices

Three tiers, $25 minimum. A bump to be on your radar, more for a written reply, more again for a call.

03

Senders pay to reach you

Cold senders get an auto-reply with your paywall. Money sits in escrow until you actually engage.

The deal

Transparent. No subscription.

You set the charity split

0 to 100% of proceeds go to a charity you pick. The rest goes to your bank.

Threshold takes 16%

One platform fee — Stripe processing and payouts come out of it. No subscription.

Money sits in escrow

No charge until you reply in Gmail. Ignore for 21 days and the sender is refunded automatically.

You are the donor of record

Charity transfers run through your connected Stripe account, so the deduction is yours at year end.
