Calculating the Return on Investment (ROI) in email marketing involves a straightforward formula:
\[ \text{ROI} = \left( \frac{\text{Revenue Generated} - \text{Cost of Campaign}}{\text{Cost of Campaign}} \right) \times 100 \]
1. Revenue Generated: Sum up the revenue directly attributable to your email campaigns. This could include sales from links clicked within emails. 2. Cost of Campaign: Total all costs associated with the campaign, including software, content creation, and other expenses. 3. Conversion Rates: Track the conversion rates from your campaigns to see how many recipients took the desired action, such as making a purchase or signing up for a service.
