Being Blacklisted Is Silent Until Your Emails Stop Arriving
A DNSBL listing doesn’t send you a notification. It just means a growing share of your mail starts landing in spam folders or getting hard-rejected outright and by the time someone notices the drop in replies, the reputation damage has been building for days.
Seabhac.io checks your IPs and domains against 50+ blocklists on a schedule, so a listing is caught within minutes of happening, not discovered by a customer complaining they never got your invoice.
How it works:
- Register your IPs and domains: Add every sending IP and domain you want tracked.
- Continuous cross-referencing: Every run queries 50+ DNSBLs — including Spamhaus and Barracuda for a listing.
- Immediate alerting: The moment a listing appears, you're notified with which list flagged you and why, so you can start the delisting process right away.
Why Speed of Detection Matters
Reputation damage compounds the longer a listing goes unnoticed receiving mail servers adjust their own internal scoring based on sustained bad signals, not just the listing itself.
- Minutes, not days between a listing occurring and you knowing about it.
- Delisting guidance know exactly which list flagged you so you can go straight to the right abuse desk or removal form.
- Trend history so you can spot a pattern (e.g. a compromised sending account) rather than treating each listing as an isolated incident.
Built Alongside DMARC Reporting
Blacklist monitoring runs on the same infrastructure as our built-in DMARC aggregate report ingestion no separate tool, no separate login, one dashboard for every signal about your sending reputation.
