What this calculator does

This tool gives you a rough estimate of how much money your email list could earn in a month and a year. It uses simple inputs you control: how big your list is, how often you send, and how engaged your subscribers are.

The result is not a guarantee, just a useful sanity check. Most people are surprised on the upside.

Why this number matters

Email is one of the cheapest ways to bring people back to your shop, salon, restaurant, or website. The ones who buy from you again are far more profitable than new customers, because you already paid to get them the first time.

If your estimate is much higher than what you spend on email, you have a clear case to send more often or grow your list. If it is lower, the usual fix is sending more relevant emails or building the list a bit faster.
