Platform / Monitoring & Insights
Know why every message lands. Or doesn't.
Deliverability you can't see is deliverability you can't fix. We attach the full story to every message, stream it to your systems, and watch the trends that predict trouble before it's visible.
Email failure is rarely binary. Between "sent" and "arrived" sit deferrals, retries, greylists, throttles, content checks, and policy gates. Each one leaves a precise trace in the SMTP conversation, and most sending stacks throw that trace away. Then placement drops, or a customer disputes a message, and the answer has to be reconstructed from rotated logs and institutional memory.
We keep the traces. Every interaction with every receiving server is recorded with its complete response, structured for querying, and retained as evidence. One discipline, never discard what the receiver said, sits underneath everything else: fast support answers, successful delistings, honest postmortems, and the feedback loops automated senders need.
One message, traced
The full conversation, preserved.

Capabilities
What the monitoring layer gives you.
Every message event, with full context
Accepts, deferrals, bounces, deliveries, and suppression hits are captured as structured events. Each carries the context that matters: destination mail server, TLS state, timing, attempt number, and the verbatim SMTP response with its status code, RFC 3463 enhanced code, and the receiver’s exact words.
Verbatim rejection evidence, preserved
When a receiver says "550 5.7.1 message rejected due to local policy, see https://...", that exact string is the difference between a successful delisting ticket and a guessing game. We keep complete responses per message. Summaries are useless when you need evidence.
Per-message tracing
Follow one message end to end. Accepted from your system, classified, routed, attempted, deferred, retried, delivered. Read its whole story in seconds. "What happened to this email?" becomes a lookup, not a cross-system investigation.
Event streams for your systems
Subscribe your applications to delivery events via webhooks and API. Bounces feed your CRM. Deliveries confirm your workflows. Suppression events keep your own lists honest. Agent feedback loops close in near real time. Your dashboards reflect reality because they share its source.
Proactive deliverability alerting
Reputation drift, blocklist exposure, authentication failures (a DKIM signature suddenly failing, an SPF record gone over its lookup limit), unusual volume patterns, rising deferral rates. All of it raises alerts: to our team always, to yours as configured. Problems get caught while they are still cheap.
A durable, independent record
Delivery history is retained durably and independently of your systems. When a customer dispute, a compliance question, or a provider escalation shows up months later, the evidence still exists. Timestamped, complete, queryable.
Trends, not just incidents
Deferral rates by destination, bounce-class composition, time-to-accept distributions, reputation trajectories per identity. The slow signals that predict placement problems weeks early, surfaced as monitorable trends with owners.
