TLDR
- Stop failures fast: flush queues, restart workers, replay a single event; if replay isn’t safe, dead-letter and log.
- Make triggers reliable: idempotent events, safe retries, durable timers, and transparent API data.
- Quick wins you can deploy now: map triggers, wire Azure Functions + Event Grid, relink CRM-mail via APIs, queue sends and verify SPF/DKIM/DMARC, validate addresses for postcards.
- Set expectations and measure progress: define SLAs, monitor time-to-follow-up and failed events, publish weekly dashboards.
- Outcome you care about: higher reliability (about 85%), faster follow-ups, fewer duplicate sends, with a clear rollback path if something goes wrong.
Triage: stop the immediate failures
A quick, safe stop fixes most broken automations. The team looks for stuck triggers, clears queues, and brings workers back online. Simple actions make follow-ups run again fast.

- Trigger stuck
- Flush the event queue, restart the worker process, then replay the event. If a replay is not safe, move the event to a dead-letter and log details for replay.
- Queue backlog
- Scale up workers or enable a short-term parallel consumer. If spikes are common, add a throttle with exponential backoff.
- Worker crash
- Inspect logs for OOM or dependency errors. Restart, roll back to the last known-good deployment, and mark the incident in the runbook.
Tactics that make triggers reliable
They use clear event rules and safe retries. Idempotent events stop duplicate mail sends. Durable timers keep follow-ups on schedule. APIs keep CRM data transparent.
How to force a stuck trigger now: flush the queue, restart the worker, and replay a single event
More technical notes (for the person who wants code-level steps)
Use Azure Functions with Event Grid to normalize events. Prefer typed payloads and an idempotency key in the event header. For long workflows, use Durable Functions (or a durable task pattern) to maintain state and set timers. In Python, check for retries with a central idempotency table (Redis or Cosmos DB) and use a conditional insert to prevent duplicates.
For CRM relinks: call the REST API with a service account token. For Salesforce or HubSpot, use the platform SDK or a thin REST wrapper. If an API call fails, capture the 4xx/5xx body and move the event to a retry queue; implement exponential backoff with jitter.
- Idempotent event
- A single event carries a unique key so the receiver can detect and ignore repeats.
- Durable timer
- A persisted timer that triggers follow-ups even after a crash or restart.
- Dead-letter
- A safe place to store events that need manual review before replay.
Step-by-step recovery and CRM-mail relink
-
Map triggers.
List every trigger: service complete, maintenance due, billing, reminder. Note the source system (ServiceTitan, Jobber, internal DB) and event schema for each.
-
Wire Azure Functions + Event Grid.
Normalize each source into a single event shape. Use a small adapter per source that emits the standard event. Add idempotency keys and minimal context (job id, customer id, event time).
-
Relink CRM-mail via APIs.
Use service credentials for HubSpot or Salesforce. Queue mail events instead of sending instantly, validate SPF/DKIM/DMARC and check auth before unpausing sends. For postcard sends (PostcardMania) push a validated send file or API payload with address verification first.
-
Set SLAs and alerting.
Define time-to-follow-up goals (example: service complete → contact within 30 minutes). Add alerts for missed SLAs and a weekly digest for the ops lead.
-
Monitor dashboards and iterate.
Track open rates, time-to-follow-up, and failed events. Publish a weekly dashboard to show trends and actions taken.
| Cause | Fix |
|---|---|
| Auth (service account missing or expired) | Rotate keys, update service account, confirm scopes. Reissue tokens and test with a dry-run. |
| Mail auth failures | Fix SPF/DKIM/DMARC records, verify sending domain, then re-enable the send queue. |
| API rate limits | Batch calls, add exponential backoff, and implement retry windows. Use a small cache to reduce duplicate lookups. |
| Bad addresses or postcard formatting | Run address validation, normalize address fields, and use a send preview step before submission (for PostcardMania or printer API). |
| Considerations: test with a staging account, log full request/responses for failed calls, and keep a small manual replay path. Keywords: SPF, DKIM, DMARC, rate limits, address validation, retry, queue, PostcardMania, HubSpot, Salesforce. | |
