Step 4: Calculate ROI

Now that you have total costs and revenue figures, use this formula to calculate email marketing ROI:

📈 ROI Formula:

ROI (%) = [(Revenue – Costs) / Costs] x 100

📌 Example Calculation:
✔ Revenue from emails: $10,000
✔ Total costs (platform, labor, ads): $2,000
✔ ROI = [($10,000 – $2,000) / $2,000] x 100
✔ ROI = 400% (A profitable campaign!)

📊 A positive ROI means your email marketing strategy is profitable, while a negative ROI suggests room for improvement.

Step 5: Analyze the Results

Once you calculate ROI, evaluate what’s working and what’s not.

📌 How to Interpret Your ROI:
✔ 🔹 Positive ROI – Your campaigns are profitable and effective.
✔ 🔸 Negative ROI – Your campaigns cost more than they generate—time to adjust!
✔ 🔹 Break-Even ROI – You’re covering costs but not making significant profit—tweak strategies for better conversion rates.
