Our story

If a tool says an email is urgent, it should tell you why.

I'm Johnny Mobley. I started building systems for other people in 2000, when I was 16, and I've been doing it ever since. Along the way I automated most of my own work, and the tools I built for myself became these companies. Each one runs on rules I wrote down, not on paid AI calls, which is why it can cost so little.

Inbox sorters decide what matters and rarely say how. I built MailguyAI's priority score so every point is visible: a deadline word adds points, a question adds points, a reply in a thread adds points, a no-reply sender or a newsletter takes points away.

It is a short list of written rules, not a trained model, and it runs in your browser, so the email you paste never leaves the page. Today it scores one email at a time; it is not yet a service that sorts your inbox for you.

What works today

• Scores how urgent an email is from its sender, subject and first line, and lists each reason with its points
• Runs entirely in your browser; the email you paste is not sent anywhere

What it doesn't do yet

Mailstrom still does things MailguyAI doesn't:

• Connecting to your Gmail or Outlook and sorting it for you.
• Rules that learn from where you move mail.
• Bulk cleanup: unsubscribing and deleting by sender.
• A daily digest of what was filed away, and snooze or follow-up reminders.

What it costs

Mailstrom's price is from their pricing page as of October 29, 2026. Prices change, so check theirs before you compare.
