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.
