Build Your First Flow

Verify Delivery Logs

Confirm end-to-end routing success using message and delivery attempt records.

1 min readUpdated February 24, 2026Edit this page

Why this step matters

Delivery verification confirms both routing correctness and destination behavior.

What to inspect

Message-level fields

  • Inbox ID
  • Received timestamp
  • Subject/from information

Delivery-level fields

  • Status (success, retrying, dead)
  • Attempt count
  • Last HTTP status
  • Last error message

Validation

A flow is healthy when MailHook delivery records and destination logs agree for the same event.
