Reading Campaign Logs

Log types and troubleshooting.

Open campaign logs

Select a campaign and open the Logs tab to view chronological events stored locally on your device.

Event types

Queued, sent, deferred, bounced, and webhook events appear in chronological logs.

  • email.queued — accepted for sending
  • email.sent — provider accepted
  • email.bounced — hard or soft bounce recorded
  • provider.error — SMTP/API failure

Export and reporting

Export summaries for client delivery or internal audits. Correlate webhook payloads with log lines when debugging automation.

Troubleshooting

Filter by provider profile or error code to isolate authentication vs recipient issues. Cross-reference SMTP error docs for code meanings.

Key takeaways

  • email.queued — accepted for sending
