Key Insights - 3 Insights

Why does a small number of conversions still lead to a high ROI?

Because each conversion generates significant revenue compared to the low cost of sending emails, as shown in step 7 of the execution_table.

Why is the open rate important before clicks and conversions?

Only people who open the email can click links or convert, so the open rate (step 2) limits the potential audience for further actions.

How does the low cost of email campaigns affect ROI?

Low cost (step 6) means even a few conversions can produce a large ROI percentage, as ROI depends on revenue minus cost divided by cost.

Full Transcript

This visual execution trace shows why email marketing delivers the highest return on investment (ROI). The process starts by creating and sending an email campaign to a target audience. Out of 1000 emails sent, 20% open the email, 10% of those click a link, and 5% of those clicks convert to a sale. Each conversion generates $100 revenue, while the campaign costs $10 to run. The ROI is calculated as 900%, showing that even a small number of conversions can produce a large return due to low costs. Key moments include understanding the importance of open rates, the impact of low costs, and how conversions affect ROI. The quiz tests understanding of these steps and the effect of changing costs on ROI.
