Supported MTA · GreenArrow Email Engine
BigStats plugs into GreenArrow Email Engine's Event Notification System and turns raw delivery, deferral, bounce, open and click events into deliverability reporting your team can act on — plus configurable CSV and JSON exports of the exact fields you need.

→ classified: hard · invalid_recipient · isp=gmailEvent coverage
Every accepted message and successful delivery, with sending IP, VMTA/binding, remote MTA and the receiving server's SMTP response.
Temporary failures with reason text and retry pressure per receiving domain, so throttling by a mailbox provider is visible before it turns into a bounce wave.
SMTP reply code, enhanced DSN status and diagnostic text parsed into hard/soft/block and a category — invalid recipient, mailbox full, blocklisted, throttled, policy, authentication or network.
Engagement events tied back to the campaign, recipient domain and sending IP that produced them.
Feedback-loop complaints and unsubscribe events tracked as first-class rates, per ISP and per IP.

FAQ
BigStats consumes GreenArrow Engine's Event Notification System, including injections, deliveries, deferrals, bounces, opens, clicks, unsubscribes and spam complaints. Each event's SMTP reply, enhanced DSN status and diagnostic text are retained alongside the normalized classification.
No. BigStats is read-only. It receives the event notifications GreenArrow already emits through the Event Processor and never touches queues, routing, bindings or message content.
Yes. Sending IP, VMTA/binding and remote MTA are captured on every GreenArrow event, so you can compare bounce and deferral pressure across the IP pool and isolate a warming IP or a single binding hurting placement.
Pick the exact fields you need — recipient, campaign, SMTP code, DSN status, diagnostic text, bounce category, sending IP and timestamp — and download them as CSV or pull the same rows through a read-only, token-authenticated JSON API.
