Contact
This is the contact surface for me, Christian Lehman — not a lead form and not AuthorityTech's strategy-call desk. Use it when you need the person who writes here, not a sales queue.
How to reach me
There is no contact form on this origin. The public inbox is ordinary email. I read it. I do not treat it as a demo request inbox.
The public inbox is [email protected]. Use it for corrections on a post, questions about something I wrote, or press that is about me rather than an AuthorityTech placement.
What this inbox is for
Corrections, citation questions, and operator-to-operator notes about the writing. If you spotted a factual error, quote the canonical URL, the sentence, and the source you believe is missing. If you are writing about the person rather than the agency, say that in the subject line.
What this inbox is not for
AuthorityTech placements, billing, or a strategy call. Those conversations live on the agency site. Book commercial work at authoritytech.io. Category definitions, MRI Score, and research corrections belong on machinerelations.ai. I will not invent a second mailbox or a phone number to look complete.
Elsewhere
I publish on X at @ChristianLehman, on LinkedIn, and on Medium. If you only need a public profile, those links are enough — you do not need to email. An AuthorityTech strategy call can be booked at cal.com/christian-lehman-at/30min; that calendar is the agency, not a form on this origin.
