Adjusting the pool size is crucial for several reasons:
Relevance: By targeting a smaller, more specific audience, you can ensure your content is more relevant to the recipients. Engagement Rates: A well-targeted pool is more likely to respond positively, increasing your open and click-through rates. Deliverability: Sending emails to a smaller, more engaged list can improve deliverability and reduce the chances of your emails being marked as spam. Personalization: Smaller pools allow for more personalized content, which can significantly improve customer relations.
