This page is designed to help you find out whether DNSDoctor.dev is good and if it is the right choice for you.
Paste a domain and get an instant diagnosis of SPF, DMARC, DKIM, MX, DNS, blacklist and domain/SSL expiry. Every problem comes with a plain-English explanation and the exact copy-paste DNS record to fix it, generated by a validating engine rather than an AI guess.
Free, no signup:
Paid monitoring:
Also ships a REST API and an MCP server, so AI agents can run scans and read reports directly.

The fix records are generated by a deterministic engine that validates them against the actual RFC grammar and the 10-lookup limit. The AI only writes the plain-English explanation; it never writes the record itself. Most tools either show you charts and leave the fix to you, or let a language model guess at DNS records, which fails silently when the guess is wrong. We also check things the DMARC-only tools skip: blacklists, reverse DNS, domain and SSL expiry.
The free scan needs no signup and gives you the full picture in one page, with the exact record to paste for each problem. The paid side answers the question most report dashboards leave open: is it safe to move to p=reject yet? It reads your DMARC reports, tracks every sending source, and tells you when the evidence supports the next policy step. One flat plan, no per-message metering, no sales call.
Small business owners and IT folks whose email quietly lands in spam, sysadmins who want DMARC enforcement without reading XML, and MSPs managing email auth across many client domains. Also works for AI agents: there is a REST API and an MCP server, so you can run scans from your own tools.
Side project by a founder who manages domains for a few companies he supports. The pattern kept repeating: marketing signs up for some new tool, it starts sending as the domain, nobody added it to SPF, and mail disappears until a customer complains. Raw DMARC reports technically contain the answer, but nobody reads gzipped XML. So this became the tool: scan, get the exact record to fix, and monitoring that flags a new sender the day it appears.
Python does the heavy lifting, with the DMARC report pipeline built on proven open-source parsing libraries rather than being reinvented. The part that matters is architectural: record generation is plain deterministic code that validates against the RFC grammar, and the AI layer is only allowed to write explanations, never records.
We have collected here some useful links to help you find out if DNSDoctor.dev is good.
Check the traffic stats of DNSDoctor.dev on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of DNSDoctor.dev on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of DNSDoctor.dev's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of DNSDoctor.dev on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.
