How Blacklist test works
When your emails systematically land in spam, the cause is sometimes that an organisation has put your domain or your server's address on a blocklist. This tool queries the main lists and tells you whether you are on one — and if so, which, so you can request removal.
Step by step
- 1 You enter your domain name or the IP address of your sending server.
- 2 We query the known blocklists.
- 3 The result lists each organisation and its verdict, with a link to its removal procedure when it publishes one.
What to put in each field
- Domain or IP address *
* Your domain (example.com) or the IP of the machine sending your emails. If you use shared hosting, it's their IP that matters — the result then concerns all their customers, not just you.
Good to know
- No credentials are asked for.
- Being on a list is not permanent: each organisation publishes a removal procedure, often free and automatic once the cause is fixed.
