For founders & makers
Let them put their money where their mouth is.
Your site email and HN about are a free door. Vendors and agents walk through it.
Put a cover charge on your inbox. Strangers pay. People you trust get through free. Stay findable without living in inbound spam.
The sift
Three outcomes. One handle.
People you trust pass free. Strangers pay the cover. Noise never arrives.
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.
Why it fits
Stay public. Stay expensive to interrupt.
Going dark loses deals. An open personal inbox loses days. A sift handle is the door in between.
Publish one handle, not your Gmail
Put name@sift.mx on your site, deck, and about page. Your real inbox stays private; senders only ever see the sift handle.
Inner circle stays free
Allowlist your domain, board, counsel, investors, and co-founders so known traffic never hits a cover.
Vendors and LLM spray self-select
Cold “quick chats,” tool pitches, and agent outreach either put money where their mouth is—or they stay out of your week.
Operating mode
A public path that still respects your calendar.
Claim a handle
Free to create and receive. One public address for email and member chat—not five personal inboxes that never get retired.
Trust the inner circle
Domains and people who already belong in your week skip the cover entirely.
Cover the long tail
Everyone else pays for a shot at your attention—or they don't get one.
FAQ
Quick answers
Will investors get blocked?
No. Allowlist people and domains you already work with. The cover charge applies to strangers—not contacts you trust.
Is this only for email?
No. Email uses private forwarding; sift chat adds E2E encrypted member messaging under the same handle and cover rules.
Why not just use a spam filter?
Filters clean an address that is already public. A sift handle changes what you publish—so bots and spray outreach hit a cover before they hit your week.
