Domain Health & Blacklist Check
Ensure your domain is healthy and not listed on any major blacklists. A healthy domain is crucial for email deliverability and search engine rankings.
Why is Domain Health Important?
01What is a domain blacklist?
A domain blacklist is a database of domains that have been reported for sending spam, hosting malware, or engaging in other malicious activities. Being on a blacklist can severely impact your email deliverability and online reputation.
02How does this check work?
This tool queries over 50 global databases and DNS blocklists to check if your domain or IP address is listed. It also performs basic health checks on your domain configuration.
03What should I do if my domain is listed?
If your domain is listed, you need to identify the cause, fix the issue, and then request removal from the specific blacklist. This process varies depending on the blacklist provider.
04Which security headers should every domain configure?
Fundamental server hardening includes HTTP Strict Transport Security (HSTS) to enforce HTTPS, X-Frame-Options against clickjacking, and Content Security Policy (CSP) to prevent cross-site scripting (XSS).
05How do blacklist listings impact email deliverability?
Mail providers and spam filters like Spamhaus or SpamCop block incoming emails from listed server IPs or route them directly into spam folders. Continuous health monitoring safeguards your sender reputation.
