Several factors can impact how long you should run your email marketing tests. These include:
Audience Size: Larger audiences generally require shorter test durations compared to smaller ones, as they generate enough data quickly. Frequency of Emails: How often you send emails affects how quickly you can gather data. Daily emails will yield faster results than weekly ones. Seasonality: External factors like holidays or special events can skew data. It's essential to account for these when determining test duration. Test Complexity: More complex tests, such as multi-variant testing, may require longer durations to achieve statistical significance.
