Your domain isn’t just a web address. It’s your brand identity, email reputation, and security layer all in one. But just like your health, domains can develop issues quietly – until they cause real problems.

If you’re seeing any of these warning signs, it’s time for a domain health check.

1. Missing or Misconfigured Email Authentication

Email authentication records (SPF, DKIM, DMARC) prove that your emails are legitimate.

• Without them, cybercriminals can spoof your domain.
• Even small errors in setup can make your messages look suspicious.

If your records aren’t set up correctly, your brand is vulnerable.

2. Spikes in Bounces or Spoofing Attempts

Keep an eye on your email performance.

• A sudden increase in bounced emails means your deliverability is suffering.
• If you see fake emails being sent “from” your domain, that’s a major red flag.

Both issues harm your reputation and put your customers at risk.

3. Forgotten or Unmonitored Subdomains

Unused or forgotten subdomains are a favorite target for attackers.

• They can host malicious content.
• They create hidden entry points into your systems.

Every subdomain should be monitored – no exceptions.

4. Weak Domain Reputation

Even if your technical setup looks fine, your domain can still carry a poor reputation with ISPs.

• Past phishing activity or compromised accounts can blacklist your domain.
• This silently lowers deliverability and trust.

Reputation management is just as important as authentication.

5. Expiring or Outdated DNS Settings

DNS is the foundation of your domain.

• Expiring records can cause sudden outages.
• Weak or outdated DNS configurations make you vulnerable to hijacking and service disruptions.

Regular DNS audits are critical to keeping your domain secure.

Why a Domain Health Check Matters

Your domain is at the center of your email security and brand trust. Ignoring these red flags can mean:

• Lower email deliverability
• Increased risk of phishing attacks
• Damaged reputation with customers and partners

A proactive domain health check ensures you’re protected.
