About LeadLamp
LeadLamp checks your domain’s email setup live and tells you, in plain English, exactly what to fix.
Most email that lands in spam has a fixable cause: a missing DMARC record, an SPF record over its lookup limit, DKIM that was never switched on, or a server on a blacklist. The tools that find these problems usually explain them in jargon, then stop.
LeadLamp does the opposite. Every check runs live against your real DNS records, and every problem comes with the fix, written so anyone can follow it.
The tools are free and need no sign-up. Some fixes link to tools we recommend, and some of those are partner links that pay us a commission if you buy, at no extra cost to you. It never changes what a check says. How partner links work.
Checks look up public DNS records, the same records any mail server sees. We don’t publish results. We keep a private log of which domains were checked and which checks failed, so we can improve the tools, and we don’t store your IP address.
