Our IP Reputation Check Measures
Blacklist status
Your sending IP gets checked against 100+ blacklists simultaneously. A single listing can tank deliverability across all providers — even if your domain reputation is spotless. Blacklists update constantly, and IPs get flagged for spam complaints, spam traps, or suspicious activity.
Sending history signals
ISPs track bounce rates, complaint ratios, and volume patterns tied to your IP. High bounces signal a dirty list. Spam complaints above 0.1% raise flags. Sudden volume spikes from a cold IP trigger filters. The test reveals what your sending history looks like to providers.
IP neighborhood score
Shared hosting means shared risk. If other senders on your IP behave poorly, their reputation bleeds into yours. The test identifies whether your IP neighborhood is helping or hurting your deliverability — a problem only dedicated IPs solve.
Our IP Reputation Checker Analyzes Actual Email Delivery
Other IP reputation tools query blacklist databases and stop there. You can pass every blacklist check and still land in spam. Why? Because blacklists only capture known bad actors.
Our IP reputation check uses an email-based approach, analyzing actual email delivery — revealing how mailbox providers truly perceive your sending IP. The headers, the routing, the response codes — all of it. You see your reputation the way ISPs see it.

Your IP Reputation Report Will Show You
Blacklist presence
We check 100+ blacklists simultaneously. If your IP appears on any list, you'll see which ones — along with direct links to request removal. Some blacklists matter more than others (Spamhaus hits harder than obscure lists).
Provider-specific scores
Gmail, Outlook, and Yahoo each score IPs differently. Your report translates these provider-specific assessments into actionable information — showing exactly which providers trust your IP and which ones don't.
Spam signals detected
Failed authentication, suspicious headers, or misconfigured mail servers all leave traces. The report flags technical issues tied to your IP that hurt deliverability. You can verify your records using our SPF lookup, DKIM lookup, and DMARC lookup tools.
