Free Website Blacklist Check

Use our free website blacklist check to check whether your server's address is on a spam blacklist. Enter any web address below and get your result in seconds, with plain-English fixes.

Free. You see the verdict at once; add your name and email to read the full result. We only read what is public on the page.

What this website blacklist check checks

Checks the website's IP address against several well-known public blacklists such as Spamhaus, SpamCop and Barracuda.

The website blacklist check resolves your domain and its IP address and checks them against public DNS blocklists used by mail servers, such as Spamhaus. It lists any that return a listing.

Why use a website blacklist check

If your server's address is listed, email sent from it may land in spam, and filters and browsers may distrust the site. On shared hosting you can be listed because of a neighbour.

Anyone whose emails go to spam or who shares hosting. Run the website blacklist check when mail starts bouncing.

How to use the website blacklist check

  1. Paste the full address of the page you want to test into the box at the top of this page. Use the exact page you care about, such as your home page or a service page, because each page can give a different website blacklist check result.
  2. Press the button and wait a few seconds. The tool fetches the page the way a visitor and a search engine would, then runs its checks. Nothing is installed, and you only need to enter your name and email to read the full result.
  3. Read the verdict and the plain-English notes, make the changes listed under the fixes, then run the test again to confirm the problem is gone. Keep a note of the date and the result so you can show progress.

How to read your website blacklist check results

  • Pass means not listed.
  • Fail means listed on at least one list. Check which, since impact differs.

How to fix problems the website blacklist check finds

  • Find out why the address was listed (each list explains).
  • Fix the cause, then request removal.
  • Ask your host to deal with it if you share the server.

Common mistakes

  • Assuming one list means a permanent ban.
  • Sending bulk mail from a shared IP.
  • Not setting SPF, DKIM and DMARC.

Website blacklist check for Cayman Islands websites

A listing can send quotes and invoices to spam for your Cayman clients. Fix the cause, request removal from the list and set up SPF, DKIM and DMARC. Re-test with the website blacklist check.

Ranking in the Cayman Islands is a local contest: Google treats a .ky domain as aimed at the territory, and it rewards pages that name the places people search for, such as George Town, Grand Cayman, West Bay and Seven Mile Beach. After you act on your website blacklist check result, work through our SEO guides for Cayman businesses, read how the WebGuru features fit together, or see the pricing for the full report.

Cayman Islands local SEO checklist

  • Name the place in your headings and first paragraph: George Town, Grand Cayman, West Bay, Cayman Brac or Little Cayman, whichever you serve.
  • Keep your business name, address and phone number identical on your website, Google Business Profile, Facebook page and local directories.
  • Use a .ky domain where you can. Google treats country-code domains as a signal that your audience is in that country.
  • Add a Google Business Profile, ask happy customers for reviews and answer every review.
  • Write for local questions, such as hurricane preparation, work permits or ferry times, in the words your customers would use.

No. It checks the address your website runs on. Mail servers often use a different address.

Why does a list sometimes not answer?

Some lists limit lookups from shared resolvers, so we mark those as unknown instead of clean.

Does a blacklist affect Google rankings?

No. It affects email delivery and sometimes security reputation.

How do I get delisted?

Fix the cause first, then follow the list's removal process.
