Use Cases
After an e-commerce promotional email, enter your campaign cost, revenue generated, list size, and conversions to instantly calculate ROI. The industry average is 3,800% for e-commerce — see how your campaign compares.
Revenue per Email ($) tells you how much each email address in your list is worth per campaign. Divide total revenue by emails sent to get this metric and benchmark it against the $0.05–$0.25 industry range.
Effective CPA shows how much each conversion costs from your email campaign. For an e-commerce email spending $250 and generating 150 conversions, the effective CPA is $1.67 — far lower than paid channels.
Calculate Email Conversion Rate (Conversions ÷ Emails Sent × 100) across multiple campaigns to identify which subject lines, offers, or send times drive the highest conversion rates.
FAQ
The industry average email marketing ROI is approximately 3,600% ($36 return per $1 spent). E-commerce averages 3,800%, Retail reaches 4,200%, while Agency and Media typically see 2,800%–3,200%. Email consistently delivers the highest ROI of any digital marketing channel.
Email Marketing ROI = ((Revenue - Cost) / Cost) × 100. For example, if you spent $250 and generated $10,000 in revenue, your ROI = ((10,000 - 250) / 250) × 100 = 3,900%.
Include all direct costs: email platform fees (Mailchimp, Klaviyo, etc.), copywriting and design costs, list acquisition costs if applicable, and any agency fees. Do not include indirect overhead that would exist regardless of this campaign.
A conversion is any goal completion driven by the email: a purchase, a sign-up, a demo booking, a download, or any action defined as the campaign objective. Track conversions using UTM parameters or your email platform's conversion tracking.
Revenue per Subscriber = Total Revenue ÷ Total Subscribers. This tells you the average revenue each subscriber generated from this campaign. Combined with Revenue per Email, it helps you understand the relative health of your list engagement.
