Fleet-wide IP reputation monitoring for high-volume sending infrastructure.
IP FleetGuard helps sending teams see which IPs are healthy, which mailbox providers are deteriorating, and where reputation risk is building before volume is affected.
| ISP | Aff. | Sev |
|---|---|---|
| Apple / iCloud | 8/15 | Critical |
| Outlook | 4/10 | Critical |
| Comcast | 5/5 | Critical |
| IP | Stream | Sev |
|---|---|---|
| 198.51.100.78 | Brightwave Media | Critical |
| 198.51.100.213 | Meridian Mail | Critical |
| 203.0.113.170 | Harbor Media | At Risk |
As your sending grows, the deliverability picture fragments.
Across dedicated IPs, multiple domains, and several sending streams, every IP builds its own reputation with every mailbox provider, and those reputations move independently. One IP inboxes at Gmail but stalls at Outlook. One stream stays stable while another quietly degrades. A /24 looks healthy overall while a handful of IPs inside it sit on a blocklist.
Performance slips, and the team cannot tell fast enough whether the cause is the IP, the mailbox provider, the stream, or the sending pattern. Without IP-level and provider-level visibility across the whole setup, you find out after delivery has already dropped, when reply rates and revenue are already down.
One view of the whole fleet, scored per provider.
Per-provider health scores
Every sending IP carries a clear status, healthy, at risk, or critical, for each mailbox provider. You see where placement is holding and where it is slipping, instead of reading one blended number for the whole fleet.
Bounce and deferral patterns
FleetGuard reads the bounce and deferral signatures coming back from providers and surfaces blocks, throttling, and policy rejections as the patterns build, not after they have cost you a send.
Blocklist exposure
DNSBL scanning across 48+ zones through a dedicated resolver, so new listings surface on each scan and you can act before they spread across the pool.
Reputation risk, prioritized
The inference engine turns raw signals into a ranked view of where risk is building: which IPs, which providers, and how serious. Alerts go to Slack so the right person sees a shift as soon as it surfaces.
Compare health across every IP and every provider, in one view.
FleetGuard scores every sending IP from its delivery, bounce, deferral, and blocklist data and rolls it up to one status per mailbox provider. Status is driven by the worst active IP, not the average, so a single blocked IP surfaces even when fleet-wide delivery looks healthy. An IP is never shown healthy on missing data.

Apple/iCloud and Outlook critical, Comcast high-bounce, while Gmail and Yahoo hold at 100. The same picture would be invisible spread across separate provider dashboards.
Whether you run the infrastructure or the senders on it.
FleetGuard fits both sides of high-volume email, because in both cases the unit that matters is the IP and the fleet, not a single inbox or a one-off blocklist lookup.
You run the platform others send through.
See each sender's reputation per provider, catch the one IP dragging down a shared pool, and act before it touches everyone else on it. Turn reputation from a support fire-drill into something you monitor and get ahead of.
You run your own sending infrastructure.
You push volume across your own PowerMTA and several ESPs. Get one reputation picture across all of it, instead of stitching together separate provider dashboards that each tell half the story while reputation drifts in the gaps.
What makes it different.
PowerMTA-native
Ingests PMTA accounting at recipient-event granularity, a depth of signal most monitoring tools do not have. Built for senders who run their own infrastructure.
Severity-aware scoring
A listing on a fringe list is not scored like a Spamhaus block. Each zone carries listing context and weight, so the score reflects what actually moves inbox placement.
Honest status, always
An IP is never shown healthy on missing data. No telemetry means "no data," not a green light, so you can trust what the dashboard tells you.
Built for performance and high-volume senders
Performance and affiliate senders that other monitoring tools exclude by policy are first-class here, scored on the same delivery and reputation data as every other sender.
