What is a Domain Health Check?

A domain health check is a vital diagnostic for your online presence. It evaluates key factors that determine your domain's reputation and security, ensuring your communications are trusted and delivered successfully.


About Domain Health

Think of domain health like a credit score for your website. It’s a measure of how trustworthy internet service providers (ISPs) and email clients (like Gmail and Outlook) perceive your domain. Good health means your emails land in the inbox; poor health means you risk being flagged as spam. Our tool focuses on a critical part of this health: your blacklist status.


Why Check Domain Security?

A secure domain is a reputable domain. Checking your security status helps you identify vulnerabilities that could lead to blacklisting. Proper security configurations like SPF, DKIM, and DMARC prevent spammers from spoofing your domain, which is a common reason for being blacklisted.


Protects Your Domain Reputation

Your domain reputation is invaluable. A single blacklisting incident can damage your credibility with customers and email providers. Regularly monitoring your domain allows you to catch and fix issues before they tarnish your reputation, ensuring your audience always sees you as a trusted source.


Ensures Email Deliverability

The ultimate goal of any email campaign is to reach the inbox. If your domain is on a blacklist, your email deliverability will plummet as major providers will automatically block your messages or send them straight to the spam folder. A clean bill of health is the first step to successful email delivery.


Why Blacklist Checking Matters

Ignoring your blacklist status is like sending your important messages into a black hole. Understanding what blacklists are and how they work is essential for anyone who relies on email.


What are Email Blacklists?

Email blacklists (also known as DNSBLs or Blocklists) are real-time databases that identify domains and IP addresses believed to be sending spam. Mailbox providers use these lists to filter out unwanted emails and protect their users.


Problems Caused by Blacklists

Being on a blacklist can be catastrophic for your business communications:

  • Blocked Emails: Your messages will be rejected by servers, resulting in high bounce rates.
  • Failed Campaigns: Marketing emails, newsletters, and transactional messages won't reach your audience.
  • Wasted Resources: Time and money spent on email marketing are lost.
  • Damaged Credibility: Customers and partners may not receive crucial communications.


How Blacklists Affect Email Deliverability

When you send an email, the recipient's server checks your domain and IP address against dozens of blacklists. If it finds a match, it may take several actions:

  1. Reject the email entirely.
  2. Quarantine the email for review.
  3. Deliver it directly to the spam or junk folder.

Any of these outcomes drastically reduces the effectiveness of your communication.


Domain Reputation Risks

Every time your domain is found on a blacklist, its reputation score takes a hit. The lower your reputation, the more skeptical email providers become. Even after you get removed from a list, a history of being blacklisted can make it harder to achieve high deliverability rates in the future.
