RBL Toolbox watches your sending IPs against SpamHaus, Spamcop, Barracuda and dozens more. We email you the moment anything changes.
From £9/mo + VAT. Cancel any time.
Comprehensive blacklist monitoring built for ISPs and hosting providers.
Every IP is checked on a cadence you pick, from every 15 minutes to every 4 hours. The scheduler runs every minute, so alerts arrive as soon as we see a change.
SpamHaus ZEN, Barracuda and Spamcop are enabled by default. Add any DNS-based zone you rely on — zen.spamhaus.org, b.barracudacentral.org — and we'll include it in the next cycle.
When an IP is listed or delisted we email your team straight away. A daily summary arrives at 08:00 with the overall picture.
From a single relay to a fifty-IP agency setup.
Starter £9/mo · Pro £29/mo · Agency £79/mo — all + VAT
