How it works
Attention with a gate—not another spam folder.
One public handle. Trusted people pass free. Unknowns pay the cover you set—or they never reach you.
sift.mx sits in front of the inbox and chat you already use. It is private forwarding for email, end-to-end encryption for member chat, and an attention price for strangers.
The sift
Three outcomes. Instantly clear.
Trusted
Passes freePeople you trust — and domains you allowlist — reach you with zero friction.
Stranger
Pays the coverUnknowns put money where their mouth is. Settled covers go to you.
Noise
Never arrivesBlocked senders and unpaid covers never touch your real inbox.
From zero to live
Five steps. No migration drama.
Keep Gmail, Fastmail, or whatever you already live in. sift.mx is the public gate—not a rip-and-replace mail host.
Claim your sift handle
Create a free account and take name@sift.mx. That is the public identity you share—never your personal inbox.
Connect a private destination
Verify the inbox where approved email should land. Senders never see that address. Replies stay behind opaque sift proxies.
Set trusted contacts and covers
Whitelist people and domains who should always get through. Choose a cover in credits for everyone else—on email and on chat.
Share the handle everywhere
Put it on your site, bio, deck, or support page. Trusted traffic passes free. Unknowns hit a payment challenge for that message.
Get paid—or stay uninterrupted
When they pay, email is privately forwarded, or chat arrives under end-to-end encryption between members. Unpaid challenges expire quietly.
