What we check
We monitor your domain against major email blacklists
We monitor your domain against major email blacklists and reputation databases to detect if you have been flagged. Being blacklisted means your emails are automatically rejected or marked as spam by major email providers, destroying deliverability and requiring immediate action to remediate.
Security Impact
Why domain reputation monitoring is critical
Blacklisting blocks all your emails
When your domain is blacklisted, major email providers automatically reject or spam ALL your emails—even legitimate ones. This can happen overnight and completely destroy email deliverability.
Reputation damage takes months to fix
Getting blacklisted severely damages your sender reputation. Even after delisting, it takes months of perfect sending behavior to rebuild trust with email providers.
Often happens without warning
Domains get blacklisted from compromised accounts sending spam, shared IP issues, or sudden volume spikes. You often won't know until emails stop delivering.
Business communication fails
Blacklisting affects all email types: transactional, marketing, customer support. Your entire email-based business communication can grind to a halt.

How to manage domain reputation
With Httpeace
Httpeace automatically monitors your domain against major blacklists:
- Add your domain to Httpeace
- We check blacklist status automatically every day
- Get instant alerts when your domain appears on any blacklist
- See which blacklist and delisting instructions in your dashboard
Without Httpeace
Manual blacklist monitoring requires checking dozens of databases:
# Check multiple blacklists manually # Visit: https://mxtoolbox.com/blacklists.aspx # Visit: https://multirbl.valli.org/ # Check specific blacklist dig yourdomain.com.zen.spamhaus.org # Check dozens of individual blacklists dig yourdomain.com.dnsbl.sorbs.net dig yourdomain.com.bl.spamcop.net # And many more...
You'll need to:
- Check dozens of major blacklists manually (Spamhaus, SURBL, SpamCop, Barracuda, SORBS, UCEPROTECT, etc.)
- Use multiple online tools since no single tool checks all blacklists
- Run checks daily to catch blacklisting quickly
- Monitor spam complaint rates (keep below 0.1%)
- Implement SPF, DKIM, and DMARC to prevent spoofing
- Use double opt-in for email subscriptions
- Clean email lists regularly—remove bounces and inactive users
- Gradually ramp up email volume—avoid sudden spikes
- If blacklisted, identify the cause immediately (compromised accounts, spam sources)
- Fix underlying problems before requesting delisting
- Request delisting from each blacklist separately (different forms/processes)
- Monitor for relisting after delisting
- Use subdomains for bulk/marketing email to isolate reputation risk
- Secure all accounts to prevent compromise
- Document all email sending practices for audit trail
Blacklist monitoring is tedious and time-consuming. By the time you discover blacklisting manually, significant damage has already occurred. Recovery requires weeks of perfect sending behavior to rebuild reputation.
FAQ
Frequently asked questions
How do domains get blacklisted?
Common causes: compromised accounts sending spam, poor list hygiene (sending to invalid/old addresses), high spam complaint rates, sending from shared IPs with bad reputation, sudden large volume increases, or sending to spam traps (abandoned email addresses used to catch spammers).
How long does blacklisting last?
It depends on the blacklist. Some auto-delist after 24-48 hours if spam stops. Others require manual delisting requests. Some are time-based (30-90 days), while others are permanent until you request removal and prove you've fixed the issue.
Can I prevent blacklisting with email authentication?
Email authentication (SPF, DKIM, DMARC) helps significantly but isn't a guarantee. It prevents domain spoofing and shows you're a legitimate sender. However, you can still get blacklisted for poor list practices, high complaint rates, or account compromises.
Should I use a subdomain for marketing emails?
Yes! Using marketing.yourdomain.com for bulk/marketing email isolates reputation risk. If your marketing emails get blacklisted, your main domain (used for transactional emails) remains unaffected. This is a best practice for protecting critical business email.
How often does Httpeace check blacklists?
We check your domain daily against dozens of major blacklists and reputation databases. We alert you immediately if your domain appears on any blacklist, giving you time to investigate and remediate before serious damage occurs.
