OptMsg: Private, Secure, Simple Email Everyone else decides what lands in your inbox. A retailer you bought from once. A list you never joined. A message pretending to be your bank. OptMsg puts that decision back with you. OptMsg is patent-pending opt-in email: mail from a sender you have not approved goes straight to Trash, and Trash empties itself after 30 days. You decide who gets in, and you can change your mind at any time. You Decide Who Gets In • Mail from senders you haven't approved goes to Trash, not your Inbox. • Easily grant or revoke access to your inbox. • Auto-delete trash after 30 days—no clutter, no wasted space. Private Always • Fully encrypted for secure messaging between OptMsg users. • Mail you send to an address outside OptMsg may still be read or monetized by that provider. • OptMsg does not scan your emails to sell ads. • No ads. We don't collect your personal data to sell to advertisers.
