Monitoring that catches problems before your reply rate does
Three layers of monitoring on every mailbox — continuous blacklist scans across 50+ RBLs, DNS drift detection, unlimited placement tests. Free, not gated.
The silent failure problem
Most deliverability breakdowns are silent. Campaigns 'send fine' into spam for weeks before someone notices the reply rate dropped. Continuous monitoring is the only fix — you can't manually re-check 200 mailboxes every Monday.
What we monitor
Blacklist presence across 50+ RBLs (Spamhaus, Barracuda, SpamCop, SORBS, and the long tail), DNS record drift (SPF, DKIM, DMARC, MX changes), per-mailbox inbox placement via test sends, bounce and reply rates per mailbox, and complaint rate trends.
Reports + alerts
Weekly Monday digest per workspace. Real-time alerts on blacklist hits, DNS drift, or sudden bounce-rate jumps. All free — comparable standalone tools charge $30–50/mo, and InboxKit gates monitoring behind their top tier.

More from the platform
Every mailbox gets warmup automatically — not as a $3/mo add-on, not as a tier upsell. Free, isolated, and matched to a human ramp schedule.
Bans are a statistical certainty at scale — plan for them. One-click or webhook-triggered replacement, new identity, re-exported to your sequencer. Always free.
