Blocklist check
Email blocklist check
If your emails bounce or vanish into spam, your mail server may be on a blocklist. Enter your email domain, the part after the @, and we check your mail servers and your website address against public blocklists. You can also enter a single IP address.
We check from the outside, the way visitors see your site, and keep a simple log of sites checked. Privacy policy.
How it works
What this checks
- Mail servers and website Finds your mail servers (MX records) and your website address, and checks each IPv4 address.
- Trusted answers only Each blocklist is asked about its own test address first. If a list refuses us or gives an answer we cannot trust, we say "Could not check" instead of a false "Not listed".
- Who listed you Which list named you, what that list tracks and where to ask for removal.
- Lists we cannot query Links to the free lookup pages of lists that do not allow lookups from a public tool like this one, such as Spamhaus and Barracuda.
