One-off Blocklist Checks Don't Keep Up With Changing Sender Reputation
Mailbox providers evaluate your reputation continuously, every send, every campaign, every day. A check you ran last month tells you nothing about where you stand right now.
You find out when sends are already failing, a bounce spike, a drop in open rates, a client escalation. By then, the listing has been active for hours, sometimes days.
Knowing you're listed doesn't tell you what to do
Spamhaus SBL or PBL? Your IP or your domain? Is it hitting Gmail, Outlook, or both? Free tools stop at the flag and leave you to figure out the rest.
The "listed" label doesn't tell you what caused it
A broken SPF record. A compromised list segment. An unwarmed sending IP. Mailora doesn't just flag the listing. It tells you what caused it and what to do next.
What Mailora Does That a Free Lookup Can't
Continuous Monitoring Across 40+ DNSBLs and RBLs
A new listing can appear at any point between your sends. Mailora watches your domains and IPs continuously across Spamhaus, Barracuda, URIBL, CBL, and 40+ more, and alerts you the moment something changes. No manual checks. No missed windows.
- Spamhaus, Barracuda, URIBL, CBL, and 40+ more.
- Automatic alerts instead of daily digests.
- No manual checks. No missed windows.
Know Which List You're On, and What It Means
Most tools stop at the flag "listed". Mailora tells you the specific list you're on, such as Spamhaus SBL, XBL, or PBL, and tracks how that status changes over time so you can tell a one-off incident from a recurring sending problem.
- Which specific list, such as SBL, XBL, or PBL.
- Listed and delisted events tracked over time.
- History graph per IP and domain.

What's Inside Mailora Blocklist Monitoring
From detection to your next send, here's what you get.
40+ DNSBL/RBL Monitoring
Spamhaus SBL, XBL, PBL. Barracuda, URIBL, CBL, and more. Continuous status checks across the lists that mailbox providers actually consult, not cached results from a one-off lookup.
Automated Listing Alerts
Get notified when a new listing is detected, instead of discovering it days later when bounces spike and open rates drop. You act the same day, not after a campaign has already underperformed.
Pre-Send Testing
Check blocklist status, authentication, and inbox placement before a campaign goes out. Catch issues before they affect your sends rather than diagnosing them afterwards.
Multi-Domain and Multi-IP Dashboards
Monitor your entire sending infrastructure from one view. Built for agencies and multi-brand senders managing IPs and domains across multiple clients and products.
