The free email check
When you run the check, your browser asks Cloudflare's public DNS resolver (cloudflare-dns.com) for the domain's public MX, SPF and DMARC records. The request goes from your browser to Cloudflare directly. This website does not receive, log or store the domain you enter or the results.
This website
There are no cookies, no analytics and no advertising trackers. Fonts load from Google Fonts. The site is hosted on Cloudflare, which keeps standard server logs.
When you contact me
If you email jmarc@smallofficesecurity.com, I use the contact details and information you provide to reply and, if you become a client, to do the work. I do not sell or share them. Ask me to delete them at any time.
Client work
Anything I see while working on your systems is covered by our written agreement, and for healthcare clients by a business associate agreement. I do not keep client data on my own devices.
