What is Cost Per Acquisition (CPA)?
Cost Per Acquisition (CPA) is a crucial metric in digital marketing that measures the cost associated with acquiring a new customer or a specified action, such as a purchase, registration, or download. In the context of
email marketing, CPA is often used to evaluate the efficiency and effectiveness of email campaigns by calculating how much it costs to gain a new customer through email efforts.
How is CPA Calculated?
CPA is calculated by dividing the total cost of the email marketing campaign by the number of acquisitions (customers or actions) generated from that campaign. The formula looks like this:
CPA = Total Campaign Cost / Number of Acquisitions
For instance, if you spend $1,000 on an email campaign and it results in 50 new customers, your CPA would be $20.Why is CPA Important?
Understanding your CPA helps in assessing the profitability and
ROI of your email marketing campaigns. A lower CPA indicates a more efficient campaign, allowing marketers to allocate budgets more effectively and optimize future email strategies. It also helps in identifying which email tactics and
target audiences are most cost-effective.
