Monitor Your Email Reputation
Ensure your domain and IP are not blacklisted, which can cause emails to be rejected or sent to spam
Email blacklists (DNSBLs) are databases of IP addresses and domains known for sending spam. If your IP or domain appears on a blacklist, your emails may be rejected or sent to spam by receiving mail servers. Our checker scans 10 major blacklists simultaneously.

Frequently Asked Questions
How do I get delisted?
Each blacklist has its own delisting process. Visit the blacklist's website and look for a removal or delisting request form. Fix the underlying issue first.
Why am I blacklisted?
Common reasons include sending spam, compromised servers, open relays, high bounce rates, or sharing an IP with a spammer (on shared hosting).
How often should I check?
Check weekly for production email servers. Set up automated monitoring for critical domains.
