OptMsg vs Kimpa

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. Security First • No Passwords – protect your inbox and your other online accounts • Uses Passkeys for seamless, password-free authentication • Your OptMsg account has no password, so a password stolen from another site can't open your inbox. Simple by Design • Clean, intuitive design for effortless email management. • No complicated settings—just straightforward, secure communication. • Reliable performance to keep your inbox running smoothly. Other Key Features • A new clean, @optmsg.com email address others can trust • Send and receive emails and attachments with ease • Keep your inbox tidy and clean with tags and simple swipe-gestures • Receive important notifications • Manage your contacts • Use Community Recommendations to identify new senders of interest • Make OptMsg your default email app We're constantly improving OptMsg — new features, and steady work on email security.
