DNS, MX, SPF & blacklist checker
MXToolbox-style basics without the account wall: DNS records, mail exchangers, SPF/DMARC/DKIM probes and a sample of major public blacklists. Built for launches, host moves and “why is mail going to spam?” moments.

What this free DNS tool covers
People open MXToolbox for the same daily questions: What is my MX? Is SPF/DMARC set? Am I on a blacklist? This free DNS, MX, SPF and blacklist checker answers those with shareable links — then you can jump to the HTTP status checker for web-side health or the SSL tool after a host move.
It does not replace paid monitoring, SMTP conversation tests or inbox placement labs. For client mail that must land, use a written deliverability plan with hosting and DNS under one roof.
Jamie Freeman is a UK web designer and developer — WordPress, WooCommerce, custom PHP and managed hosting. Free DNS checks help you diagnose; paid work is for fixing records and mail properly.
FAQ
DNS tool questions
What DNS records does this tool check?
For a domain it can fetch A, AAAA, MX, NS, TXT, SOA and CNAME. Modes focus on MX only, email authentication (SPF/DMARC/DKIM), or blacklist sampling of resolved IPs.
Is this like MXToolbox?
It covers the everyday free checks people run on MXToolbox — MX priority, SPF/DMARC, common DKIM selectors and a light multi-RBL blacklist peek — without accounts or monitoring plans.
Does a clean blacklist result mean mail will deliver?
No. We sample popular public DNSBLs only. Deliverability also depends on content, volume, engagement, authentication alignment and recipient filters.
Why is my DKIM missing?
DKIM lives at selector._domainkey.domain. Providers use different selectors (google, s1, default…). Enter yours in the DKIM field if the common list does not find it.
Can you set up DNS and email for my domain?
Yes. Jamie Freeman configures domains, SPF/DKIM/DMARC and UK hosting so sites and mailboxes stay aligned — WordPress, custom PHP and shops. Use this free checker first, then book a call for a full deliverability setup.
Need DNS and email set up properly?
I configure domains, SPF/DKIM/DMARC and hosting so sites and mailboxes stay aligned — WordPress, custom PHP and shops.
