The frequency of your performance analysis can vary based on the scale and frequency of your email campaigns. For example:
Weekly: For businesses that send emails multiple times a week, a weekly analysis can help you quickly identify issues and make timely adjustments. Monthly: If you send emails less frequently, a monthly review might be sufficient to gather enough data for meaningful insights. Campaign-Based: Conduct an analysis after the end of each campaign to evaluate its specific performance and apply learnings to future campaigns.
