Several factors can affect throughput in email marketing:
Email List Quality: A high-quality, well-segmented email list improves deliverability and engagement rates. Sender Reputation: ISPs monitor your sending behavior; a good reputation increases the likelihood of your emails reaching the inbox. Content Relevance: Personalized, relevant content boosts open and click-through rates. Timing and Frequency: Sending emails at optimal times and maintaining a consistent but not overwhelming frequency can improve engagement.
