How to use this checklist
A marketing automation system is a chain from lead capture to sales handoff. A break at any stage affects every stage after it. Work through this checklist in order. When you find a failure, fix it before checking later stages, because a later stage cannot work if an earlier one is broken. The checklist covers the full journey so you can find the first point of failure.
| Stage | What should happen | What to check |
|---|---|---|
| Lead capture | Form submission recorded | Form entries and field capture |
| Contact creation | Contact created or updated | CRM search for the lead |
| Source data | UTMs and click IDs stored | Source fields on the contact |
| Lead assignment | Correct rep assigned | Assignment rules and owner field |
| Opportunity | Opportunity in correct pipeline and stage | Opportunity record and pipeline |
| Notification | Rep notified | Notification delivery and visibility |
| Follow-up | Nurture begins | Workflow entry and first action |
| Reply | Reply detected and nurture changes | Reply detection and stop logic |
| Appointment | Booking recorded and CRM updated | Calendar record and contact link |
| Conversion | Customer status stops prospect automation | Exit condition on conversion |
1. Lead capture and form submission
- The form submission appears in the form platform entries list.
- Every required field was captured, including hidden fields for source tracking.
- UTM parameters and click IDs were stored if the campaign uses them.
- The form is the same form the trigger references.
If the submission is missing or incomplete, the problem is the form, not the automation. Form capture problems are covered in the guide on form submission automation not triggering and the guide on automation missing form data.
2. Contact creation and data mapping
- A contact was created or updated in the CRM.
- Each form field mapped to the correct CRM field.
- Source data such as UTMs and lead source was stored on the contact.
- No duplicate contact was created by a matching failure.
If the contact is missing or fields are empty, the problem is the integration or mapping. Data mapping is covered in the guide on webhook data mapping wrong and duplicate contacts in the guide on automation creating duplicate CRM contacts.
3. Lead assignment and opportunity creation
- The lead was assigned to the correct rep or team.
- An opportunity was created if the process requires one.
- The opportunity landed in the correct pipeline and stage.
- Round robin distribution was even if that method is used.
Assignment problems are covered in the guide on automation lead assignment not working and round robin in the guide on automation round robin distribution uneven. Opportunity creation problems are covered in the guide on automation contact created opportunity missing and the guide on automation opportunity wrong pipeline stage.
4. Notifications and follow-up
- The assigned rep received a notification.
- The nurture or follow-up workflow started.
- The first message sent at the expected time.
- No duplicate messages were sent by overlapping workflows.
Notification problems are covered in the guide on automation notifications not sending. Duplicate messaging is covered in the guide on automation sending duplicate emails or SMS. Wrong-time messaging is covered in the guide on automation sending messages at the wrong time.
5. Reply handling and appointment booking
- A lead reply was detected and the nurture changed or stopped.
- An appointment booking was recorded in the calendar.
- The booking was linked to a contact and triggered the expected automation.
- Cancellations and reschedules triggered the correct workflows.
Reply handling is covered in the guide on automation keeps running after a lead replies. Appointment automation is covered in the guide on appointment booking automation not triggering and the guide on appointment cancellation reschedule automation not working. Follow-up after booking is covered in the guide on automation follow-up after appointment booked.
6. Customer conversion and sales handoff
- The lead becoming a customer stopped the prospect automation.
- The pipeline moved to the correct won stage.
- Sales handoff occurred without the automation continuing to message.
- Reporting data was updated to reflect the conversion.
Conversion exit logic is covered in the guide on automation keeps messaging after customer conversion. Conflicts between automation and the sales team are covered in the guide on CRM automation and sales team conflict.
7. Integrations, webhooks and APIs
- Webhooks fired and delivered data to the destination.
- API requests succeeded and returned the expected data.
- Data sync between apps was not delayed or missing.
- Error handling surfaced failures instead of hiding them.
Webhook problems are covered in the guide on automation webhook not firing and the guide on webhook returning error. API problems are covered in the guide on API automation authentication failed and the guide on API rate limit automation problems. Data sync is covered in the guide on automation data sync delayed and the guide on automation data missing between apps. Error handling is covered in the guide on automation error handling.
8. Platform-specific checks
- Zapier Zaps triggered and completed every step.
- Make scenarios ran without stopping mid-workflow.
- n8n workflows triggered and passed correct data between nodes.
- Each platform's error logs were reviewed for failures.
Zapier problems are covered in the guide on Zapier automation not triggering. Make problems are covered in the guide on Make scenario not running. n8n problems are covered in the guide on n8n workflow not triggering and the guide on n8n workflow stops at node.
9. Production validation
- The full journey works with a real lead, not just test data.
- Every stage passes data correctly to the next.
- No duplicate records or conflicting updates appeared.
- Failures are logged and visible for review.
Test versus production differences are covered in the guide on automation works in test but fails with real leads. The complete automation audit is covered in the guide on marketing automation audit checklist.
How to use the result
When you find a failure at a stage, fix it before moving on. A fix at an early stage often resolves symptoms that appeared later. If multiple stages have problems, address them in order from lead capture to sales handoff. Keep this checklist for repeat use, because automation systems drift over time as workflows are added and changed.
Frequently Asked Questions
How do I troubleshoot a marketing automation system end to end?
Work from lead capture to sales handoff in order. Confirm the form captured the data, the contact was created, the lead was assigned, the opportunity was created, the rep was notified, the follow-up started, replies were handled, the appointment was booked and the conversion stopped the prospect automation.
Why should I fix early stages first in an automation audit?
A break at an early stage breaks everything downstream. A missing contact means no assignment, no opportunity and no follow-up. Fix the first failure you find and retest the full journey before checking later stages.
