Your mail keeps flowing through GreenArrow. Tatami only reads the events it reports.

Trace every GreenArrow problem to its cause.

A GreenArrow delivery attempt can succeed, fail, or defer. Tatami reads those statuses alongside bounce and complaint events so your team can investigate the delivery path with SMTP responses, MTA identifiers, and sending-IP context. Bring operational evidence from your GreenArrow infrastructure into a shared monitoring view.

Fix problems before customers notice.

Tatami explains each bounce, watches your IPs and domains, and tells your team when something breaks.

Connect GreenArrow in a few minutes.

Point the GreenArrow webhook at Tatami. Your mail keeps sending the same way.

  1. 1

    Create a GreenArrow source in Tatami and copy its webhook URL. Name the source for the GreenArrow instance or traffic group you are connecting.

  2. 2

    Configure a JSON Event Notification System destination using the Tatami URL. Include delivery_attempt, bounce_all, bounce_bad_address, scomp, and engine_unsub; enable deferral and connmaxout statuses for delivery attempts.

  3. 3

    Validate the GreenArrow configuration and send a test message. Check that its delivery-attempt outcome appears in Tatami with the expected MTA and SMTP-response details.

Turn on these GreenArrow events.

Questions about monitoring GreenArrow.

Does every GreenArrow delivery_attempt count as delivered?

No. Tatami reads the status: success becomes delivered, failure becomes bounced, and deferral, deferred, or connmaxout becomes deferred. The original status and SMTP response remain available with the event.

How do I make GreenArrow deferrals visible in Tatami?

Enable delivery_attempt events and include deferral statuses in your GreenArrow event-delivery configuration. Tatami's setup instructions also include connmaxout. Without those statuses in the webhook feed, Tatami cannot report the corresponding attempts.

Does a delivered GreenArrow email mean it reached the inbox?

No. A delivery event means the receiving mail server accepted the message. It does not confirm whether it reached the inbox or spam folder. Tatami monitors the delivery events you send, bounce reasons, and sender reputation to help you investigate deliverability issues; it does not measure inbox placement.
