OptMsg is a private, opt-in email service built for people and families โ€” 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 โ€” only approved senders get through, thanks to a patent-pending opt-in router
  • Passwordless sign-in โ€” no password to steal and nothing to phish
  • No ads โ€” and your data is never sold
  • A clean inbox โ€” 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.

  • Spark/xtra issues
    Also, if you're also trying to use Xtra email in Microsoft Outlook, also expect problems. Outlook is also crap. There are other email application options. Em Client (emclient.com) is an excellent alternative to Outlook. Source: almost 3 years ago
  • What's the biggest missing piece of the puzzle in the self-hosted universe?
    Totally agree on the security risk. On the other hand setting up, maintaining and explaining PGP for non-technical users usually leads to not using encryption at all, which is by far less secure than a self-managed PGP gateway on a private mail server setup. I'm aware of the few UX friendly implementations like eM client or pEp, but even those are for most not easy or "automatic" to use. (especially without good... Source: over 4 years ago
