OptMsg is a private, opt-in email service built for people and families — not businesses.

Unlike free inboxes that let anyone reach you, flood you with spam, and profit from your data, OptMsg puts you in control: only senders you approve can message you, and everything else goes straight to Trash. There's no spam to sort and nothing dangerous to click.

Why people switch to OptMsg:

  • Opt-in inbox — only approved senders get through, thanks to a patent-pending opt-in router
  • Passwordless sign-in — no password to steal and nothing to phish
  • No ads — and your data is never sold
  • A clean inbox — no junk to flag, filter, or delete
  • 15GB storage on paid plans, plus Community Recommendations to help vouch for safe senders
  • Full encryption when both people use OptMsg

OptMsg runs on the web, iOS, and Android. Start free with the Reader plan, or upgrade from $49.99/year.

Your Inbox. Your Rules.
