Check one or more domains against VirusTotal, Google Safe Browsing, AbuseIPDB, and RDAP.
Enter one or multiple domains separated by commas or new lines. RDAP + DNS run without any API keys.
No domains being monitored. Add one above.
Paste a real URL (e.g. http://t2.cloudmintworks.com/aff_c?offer_id=847&aff_id=2093)
and the domain will be stripped automatically. Use {domain} if you type a template directly.
Both the manual check and domain monitor use this list.
No history yet.
For each domain, resolves its MX records, checks whether those MX hosts publish an IPv6 (AAAA) address, then tests a real TCP connection to port 25 over IPv6 from this server. Helps you understand what percentage of your send list can receive mail over IPv6 before you set up your mail server.
Score and rank IP addresses for email deliverability. Checks Spamhaus SBL, Barracuda, SpamCop, SenderScore, FCrDNS (forward-confirmed reverse DNS), AbuseIPDB, geolocation, and port 25 connectivity.
Geolocation via ip-api.com runs automatically — no key needed. BulkBlacklist key required for blacklist + SenderScore checks. AbuseIPDB is optional.
Track your /24 IP ranges — ownership, RDNS coverage, SBL status, usage history, and build mailer spreadsheets.
