Authentication Testing
Verify SPF, DKIM, and DMARC records are properly configured. Use tools like MXToolbox or Google Admin Toolbox to validate DNS settings.
Rendering Testing
Test email rendering across 50+ email clients and devices. Gmail, Outlook, and Apple Mail handle HTML differently—test all variations.
Seed List Testing
Send test emails to seed addresses at major providers (Gmail, Yahoo, Outlook) to verify inbox placement before full deployment.
Provider-Specific Considerations
Different email providers have varying deliverability rates. According to 2026 research:
Highest inbox placement
6.96% improvement in Q2 2025
Higher than US average
Workflow and Trigger Testing
Workflow testing ensures your automated sequences execute exactly as designed. According to iPresso's audit methodology, systematic workflow testing can identify gaps in your automation before they impact customers.
Trigger Validation
Test each trigger condition by simulating the exact user action that should activate it.
Timing and Delay Testing
Verify that wait steps, delays, and scheduled sends execute at the correct times.
Branching Logic Testing
Test all conditional paths to ensure contacts are routed correctly based on their attributes or behavior.
Exit and Goal Testing
Confirm that contacts exit workflows appropriately and conversions are tracked.
Workflow Testing Best Practices
Integration and API Testing
Modern marketing automation platforms rely on marketing integrations with CRMs, analytics tools, and other systems. According to integration testing research, API integration testing validates communication between different services, ensuring APIs exchange data correctly.
| Integration Type | What to Test | Common Failure Points |
|---|---|---|
| CRM Sync | Bidirectional data flow, field mapping accuracy, sync frequency | Duplicate records, field mismatches, sync delays |
| E-commerce Platform | Order data, product catalog, customer history | Cart abandonment triggers, product data staleness |
| Analytics Tools | Event tracking, conversion attribution, UTM handling | Pixel firing issues, attribution gaps, data discrepancies |
| Webhooks | Endpoint availability, payload format, authentication | Timeout errors, authentication failures, payload changes |
| Form Builders | Form submissions, field mapping, lead creation | Missing required fields, validation errors, duplicate handling |
Running Effective Pilot Campaigns
Pilot campaigns bridge the gap between testing and full deployment. According to 2026 marketing automation best practices, you should pilot new tools with 1-2 clients or segments for 60-90 days before deploying across all accounts.

Common Testing Mistakes to Avoid
According to common automation mistakes research, rushing into automation without a clear marketing plan results in wasted effort, disengaged customers, and campaigns that fail to deliver measurable results.
With 16.9% of emails never reaching inboxes, skipping deliverability testing is the costliest mistake. Always test inbox placement across major providers before any campaign launch.
Over 60% of emails are opened on mobile devices. Always test rendering and functionality on multiple screen sizes and operating systems.
Testing with real customer data without proper safeguards can lead to embarrassing—or illegal—mistakes. Create test contacts or sanitize data before testing.
Running pilots for only 1-2 weeks does not provide statistically significant data. Commit to 60-90 day pilots to catch seasonal variations and edge cases.
Testing only the happy path leaves you vulnerable when APIs fail, data is missing, or services are unavailable. Test error handling and fallback behaviors.
Without documentation, you cannot prove what was tested, replicate issues, or onboard new team members. Maintain a test case repository with expected outcomes.
The True Cost of Automation Testing
According to BrightCarbon's analysis, the true cost of marketing automation is in the time and attention of marketers. Making automation work is incredibly time-consuming—creating emails, campaigns, and content that people actually want requires significant investment. Some companies could easily have somebody working full-time on trying to get value from their automation platform.
