How do you test timing accuracy?

Timing accuracy testing verifies delays and schedules work as configured:

Timestamp logging: Record when triggers fire. Record when each automation step executes. Calculate actual delays and compare to configured delays.

Short delay testing: Test delays you can observe in real-time (minutes rather than days). Verify the automation advances when expected.

Time-zone validation: Test with recipients in different time zones. Verify sends occur at intended local times. Check edge cases like daylight saving transitions.

Send-time optimization testing: If using STO, verify sends distribute across expected windows. Confirm fallback behavior for recipients without history.

Long delay considerations: For multi-day delays, use staging environments with accelerated time. Or accept longer testing cycles for production validation.

Timing that seems right in configuration may behave differently in execution. Only testing reveals the truth.
