# Mailing Lists

**Mailing Lists:** A useful tool for sharing information with groups, often used for newsletters, announcements, and discussions. They help distribute information quickly and engage people.

This graph shows the growth of a company’s email mailing list over the selected period. The y-axis shows the number of New subscribers and the total subscribers, while the x-axis shows time. Here are the metrics displayed in the graph:

* **Mailing Lists:** It shows the number of active mailing lists associated with the project per the selected period.
* **New Subscribers:** This is the number of people signed up for the company’s email mailing list in a month. Hover over the bar chart to see the new subscribers for that month. For instance, In August, there were 4 new subscribers.
* **Total Subscribers:** This is the total number of people signed up for the company’s email mailing list. Hover over the line chart to see the total number.

The following metrics are not shown but can be analyzed from the chart.

**Growth Rate:**

This metric is not shown in the graph but can be calculated by subtracting the number of total subscribers at the beginning of a period from the number of total subscribers at the end of the period and then dividing it by the number of total subscribers at the beginning of the period.

Then multiply by 100 to express the growth as a percentage. For example, the growth rate from March to April was 1%.

**Subscriber Acquisition Rate:** While the graph doesn't show individual monthly growth rates, you can calculate them to identify periods of stronger subscriber acquisition.

This helps you understand what strategies are working best and allows for targeted adjustments.\\
