A free email blacklist check that looks up your sending IPs on the blocklists that allow it, and links the ones that don't.
5.0(1 rating)Type your domain or a sending IP address. See whether it's listed, list by list, and where to ask for removal. The example is the lists' own test address, which every list shows as listed.
Your domain
DNS is read from your browser. navid.me fetches only the MTA-STS policy, the BIMI files and the domain's age. Nothing is stored.
This free email blacklist check looks up your sending IP addresses on the blocklists whose own terms allow public lookups, and links each list's page.
It only trusts lists that answer: before each check, a list must answer its own test address, or it shows as not checked instead of clean.
What is an email blacklist check?
An email blacklist check asks DNS blocklists (DNSBLs) whether an IP address is listed as a source of spam. Some receiving servers refuse or flag email from listed addresses.
Which blacklists it checks
| List | Why it's checked here |
|---|---|
| SpamCop | Free to query; it asks for donations |
| PSBL | "Anybody is free to use PSBL" |
| Mailspike | A free, community-run IP reputation list |
These aren't checked, because their terms don't allow a public checker, so each links to its own lookup:
| List | Why not |
|---|---|
| Spamhaus | Free for non-commercial use only, and it refuses public DNS |
| Barracuda | You must register the DNS server that asks |
| SURBL | Any product or service needs a paid agreement |
| URIBL | Free for low volume only; commercial use needs a data feed |

Which IPs to check
If you send through Mailchimp, Kit or another platform, its servers send your email and it watches their reputation. Your SPF record names them by include, so the check skips them.
It checks the addresses your SPF record lists itself, and the servers behind its a and mx terms: the ones you're responsible for. For a real email, the email header analyzer finds the exact IP that sent it.
What to do if you're listed
Final thoughts on email blacklists
A listing is a symptom: something sent spam from that address. Find the cause, fix it, then ask for removal.
Blocklists are one signal. Gmail, Yahoo and Outlook also check SPF, DKIM and DMARC on every email, and the email deliverability checker checks all 3.
