The ranking is determined by several factors including list quality, content relevance, and engagement metrics. Email service providers (ESPs) use algorithms to assess these parameters. Key considerations include:
Deliverability: Whether your emails reach the inbox rather than being filtered out. Engagement Metrics: This includes open rates, click rates, and the level of interaction with your emails. Content Quality: The relevance and value of the content you are providing to your subscribers. Sender Reputation: How reputable your sending domain and IP address are, based on historical performance and feedback loops.
