UK-based DNS experts helping businesses fix email deliverability since 2015.
Email DNS Health is a specialist DNS health checking and fixing service run by UK-based email deliverability experts. We help businesses stop their emails going to spam by diagnosing and fixing SPF, DKIM, DMARC and related DNS problems.
We created Email DNS Health after seeing how many businesses — from sole traders to mid-sized companies — were losing sales because their emails were landing in spam folders, and they had no idea why. The reason is almost always misconfigured DNS records. The fix is usually straightforward, but only if you know what you're doing.
Our team has been working with DNS, email authentication and mail server configuration for over a decade. We work across all major DNS providers including Cloudflare, Route 53, GoDaddy, Namecheap, Google Domains and more.
The free scan takes under 10 seconds and gives you a clear picture of what's broken. Our fix plans start at £49 for a single issue, up to £199/month for full multi-domain agency management. Every fix is done by a human expert with a before-and-after scan to prove it worked.
Every scan runs 9 critical checks in under 30 seconds.
