Definition
Private forwarding on sift.mx means your public address and your destination inbox stay separated. Only sift.mx delivers approved mail to the inbox you verified.
Public handle, private destination
Put name@sift.mx on your website, LinkedIn, or press kit. Connect Gmail, Fastmail, or another inbox you already use as the destination. Senders never learn that address from sift.mx.
Opaque replies
When you reply through the forwarded thread, correspondence continues through sift.mx proxy addresses so you do not accidentally teach strangers your real inbox.
Privacy is not the same as E2E email
Email on sift.mx uses authenticated intake and encrypted quarantine storage before private forward. It is not end-to-end encrypted email. For E2E messaging between members, use sift chat.
