SPF Records Test

What is it?

The "SPF Records Test" tool from TeckBlaze analyzes the SPF DNS TXT record of the domain in real time. You enter a URL above, we fetch the page exactly as Googlebot would, isolate the tested element, compare it to 2026 best practices, and tell you in plain words whether it passes, needs work, or is critical.

Why spf records test still matters in 2026

Without proper email configuration, anyone can send emails impersonating your domain. It's become a trust signal for Google and a compliance topic.

The newer reason: AI answer engines and link previews

AIs weight citations by authority signals, including domain legitimacy. A domain without SPF/DMARC sends a 'poorly managed' signal.

Common mistakes worth checking

• No SPF record (anyone can send on your behalf).
• No DMARC, or DMARC only in p=none mode.
• Multiple stacked SPF records (Gmail only reads the first).
• Domain without MX records despite a published email.
• Sub-domain without its own policy (mail.your-site.com).

How do I fix it?

Fixing the SPF DNS TXT record of the domain usually takes minutes once you know where to look. Below: the code example, where to edit it based on your stack, the usual causes, and the best practices that keep the issue away.

Example

DNS
TXT @ : v=spf1 include:_spf.google.com ~all

Where to make the change

• Cloudflare: DNS → add a TXT record.
• Google Domains / Squarespace Domains: custom DNS → TXT.
• OVH: domain DNS zone → add a TXT entry.
• GoDaddy: DNS → add a new TXT record.
• Technical host: DNS panel in your provider, propagation 1–24 h.

Common causes and resolution

• Theme or CMS template that does not handle the SPF DNS TXT record of the domain cleanly.
• Recent site updates that overwrote a previous fix.
• Domain or platform migration with configuration not carried over.
• Misconfigured SEO plugin overwriting the SPF DNS TXT record of the domain defined elsewhere.

Best practices

• Document the SPF DNS TXT record of the domain in a release checklist.
• Test in pre-prod before every major deploy.
• Monitor continuously (weekly audits or CI integration).
• Track changes for easy rollback.
• Train the content team on basic SEO rules.
