What is sift.mx?
sift.mx is a sift handle for email and chat: trusted contacts get through free, unknown people pay a cover you set.
How paid email and cover charges work
Unknown senders pay your cover to get a message delivered to your private inbox. Trusted contacts stay free.
Get paid when unknowns email you
Turn cold pitches and low-intent mail into cover payments—or sift them out—without exposing your real inbox.
Privacy
Hide your real email with private forwarding
Share @sift.mx publicly. Keep your personal or work inbox verified privately—senders never see it.
Rules
Whitelist, pay-to-deliver, or block
Three outcomes for inbound mail and chat: trusted free, cover required, or sifted out.
Getting started
How to claim your sift handle
Claim name@sift.mx, verify a destination inbox, set your cover, and start sharing one handle for email and chat.
Chat
End-to-end encrypted paid chat
Member-to-member sift chat is E2E encrypted. Whitelist free; strangers pay your cover per message.
Creators
Creators: filter collabs and cold pitches
Put a sift handle in your bio so brands and pitch bots pay for access—while managers and partners stay whitelisted.
Founders
Founders: protect focus without going dark
Stay reachable for investors and customers you trust—while unknown intros pay for a slot on your calendar brain.
Inbox teams
Sales and support: qualify inbound without drowning
Use a sift handle in front of shared inboxes so tire-kickers pay or drop—while known accounts stay free.
Attention economy
Why free attention invites spam
When contacting you costs nothing, strangers over-consume your time. An attention tax restores the price signal.
Compare
sift.mx vs traditional spam filters
