Project your email list growth, churn impact, and revenue potential over time.
Monthly increase in new subscriber rate
Email list growth is the net result of new subscribers minus churned subscribers each month. The key to healthy list growth is maximizing acquisition while minimizing unsubscribes through relevant, valuable content.
Your email list is one of your most valuable marketing assets, but growing it sustainably requires understanding the interplay between new subscriber acquisition and churn. Our free Email List Growth Calculator projects your list size over time by factoring in your current subscriber count, monthly acquisition rate, unsubscribe rate, and revenue per subscriber. This gives you a realistic forecast of list growth and the revenue potential tied to your email channel.
Email marketers, ecommerce store owners, SaaS companies, and content creators all benefit from this calculator. If you are investing in lead magnets, pop-ups, paid acquisition, or content marketing to grow your list, this tool helps you set realistic growth targets and understand when your list will reach key milestones. It is particularly useful for building business cases around email marketing investment and forecasting the revenue impact of improved acquisition or retention strategies.
The projection chart shows your expected list size month by month, accounting for both new subscribers and those who unsubscribe. Pay attention to the net growth rate, which is your acquisition rate minus your churn rate. If churn is close to or exceeding acquisition, your list will stagnate regardless of how much you spend on growth. Focus on reducing churn through better segmentation, relevant content, and proper email frequency before scaling acquisition spend. A healthy email list typically sees monthly churn rates below two to three percent.
