How to check SPF, DKIM, and domain setup without command line
You don’t need to open a terminal window to check your DNS anymore.
Ever stared at a black screen wondering whether to type dig, nslookup, or just given up? This one’s for you.
Here’s how to see what your domain is really publishing (and what the rest of the internet sees). Use tools like ViewDNS.info, which is our favourite free tool for quick checks.
Know What You’re Looking At
DNS (Domain Name System) is the internet’s address book. It translates names like quinset.co.uk into IP addresses computers understand.
But DNS does more than route websites. It’s what makes email deliverable and secure.
A small error here can cause:
- Legit emails landing in spam
- Broken website links
- Security gaps open to spoofing
So before you chase content or CRM issues, it’s worth confirming your DNS is clean.
Meet ViewDNS.info
ViewDNS.info is a simple, web-based toolkit that lets you check:
- DNS records (A, MX, SPF, DKIM, DMARC, CNAME)
- Whois ownership info
- Blacklist status
- DNSSEC settings
Think of it as dig and whois in a friendly browser tab. No command line, no guesswork.
It’s fast, free, and surprisingly powerful for a tool that looks like it hasn’t changed much since 2010 (and that’s part of the charm).
How To Run a DNS Lookup
- Go to ViewDNS.info.
- Pick your tool… DNS Lookup, Whois Lookup, or Blacklist Check.
- Enter your domain or IP and click Go.
- Review the results.
You’ll see every DNS record published for that domain, along with any errors or gaps.
What to Check (and Why)
| Record | What it does | Why it matters for email |
|---|---|---|
| SPF | Lists authorised sending servers | Stops spoofing; must match your email platform |
| DKIM | Signs your messages with a digital key | Proves messages weren’t altered |
| DMARC | Sets how to handle failed authentication | Protects domain reputation |
| MX | Routes incoming mail | Must point to your real mail host |
| CNAME/A | Maps subdomains | Often used for tracking or web links |
If you’re missing one, or see outdated records from old suppliers, it’s time to tidy up.
Check, Fix, Test, Repeat
After updating records, try sending a test email to a Gmail and Outlook address. If it lands in spam, your DNS might look fine but your domain reputation might not. That’s where further diagnostics help.
Reality Check
DNS lookup tools don’t fix issues, they show you what’s broken. But understanding what’s published is the first step to better deliverability and fewer support tickets.
ViewDNS.info just makes that discovery part easy enough that anyone can do it, not just IT.
Call In The Cavalry
If your DNS looks right but your emails still struggle to reach inboxes, it’s probably a reputation or authentication issue.
That’s where Quinset’s deeper diagnostics come in, translating those technical checks into real deliverability fixes.
