DNS blocklist monitoring

Password reset emails never arrive - customers are locked out of their accounts and your support team is overwhelmed. Order confirmations go to spam - customers think their orders failed and place duplicates or abandon your store entirely.

Marketing campaigns have near-zero open rates. You've spent weeks crafting the perfect email, only to have it filtered into spam folders across Gmail, Outlook, and corporate email systems. Revenue lost, effort wasted.

Support ticket responses never reach customers. They're waiting for help, getting increasingly frustrated, while your replies sit in their spam folder. Your support metrics tank, customers churn.

We check the major email blocklists: Spamhaus (the industry standard), Barracuda (widely used by enterprises), SpamCop (real-time spam reporting), SURBL (multi-source domain list), and URLhaus (malware URLs).

Shared hosting: Another site on your IP sends spam. You've done nothing wrong, but your IP address gets blacklisted because a neighbor on the same server was sending spam. Suddenly your emails bounce too.

Compromised website: Attackers inject malicious content or use your site for phishing. Security scanners detect it and add your domain to blocklists. You might not even know you were compromised.

Misconfigured email server: An open relay, missing SPF/DKIM records, or overly aggressive marketing emails can get your domain flagged as a spam source.

Domain history: You registered a domain that was previously owned by bad actors. Their reputation follows the domain, not the owner. You inherit their blocklist entries.

Regardless of the cause, you need to know immediately so you can take action.
