What is Mail Security Tools?

A directory of email-security products and the MSP tools that sit next to them: DMARC, mail filtering, phishing training, RMM, PSA, backup, passwords, and free checkers. It lists 99 tools. DME Computer Services in Omaha publishes it. The site does not print a street address, because we are not going to invent one.

How are the tools ranked?

Alphabetical by name. A sponsored slot, when someone has actually paid, sits above the list and is labeled Sponsored. It does not buy a higher rank or a star rating. InboxGuards, OrionCmd, and Dragons Eye are ours. They wear a Made by us badge and stay in the same A–Z order.

Where do the free-tier notes come from?

From the vendor's own page, dated. This set was checked on 14 Oct 2026. If a page blocked a simple fetch and only loaded in a browser, the listing says so. We do not write star ratings, user counts, or prices we did not read there.

Is the free domain check a listing?

No. The check at /check reads MX, SPF, DMARC, and five common DKIM selectors once, and it does not store the domain. The listings are other products. InboxGuards is our mailbox monitoring. OrionCmd is our uptime and certificate check. Both are labeled and listed with everyone else.

Is the checklist a subscription?

No. The Small Business Email Security Checklist is a PDF for $29, paid once. Checkout is not connected on this site yet, so the sales page says Coming soon. When a buy button exists, it will be Lemon Squeezy or Gumroad, not Stripe.
