Understanding Email Marketing ROI
Email marketing remains the highest-ROI marketing channel available to businesses. Industry studies consistently show returns of $36 to $42 for every $1 invested in email. But calculating your actual ROI requires understanding all the costs involved and properly attributing revenue.
What Counts as Email Marketing Costs?
To get an accurate ROI calculation, include every cost associated with running your email program. ESP platform fees are the obvious one, but many brands undercount their true investment by forgetting agency fees, internal team time, design resources, and SMS credits.
- ESP platform fees: Your Klaviyo, Mailchimp, Omnisend, or other platform subscription based on list size and send volume.
- Agency or freelancer fees: If you work with an email marketing agency or freelancers for strategy, design, and copywriting.
- Internal team allocation: The portion of salary for employees who spend time on email marketing.
- Design and content tools: Canva, stock photos, copywriting tools, or any other creative resources.
- SMS credits: If your platform includes SMS and you use it as part of your email and SMS strategy.
- List building costs: Pop-up tools, lead magnets, or paid list growth tactics.
Flows vs. Campaigns: Where Does Email Revenue Come From?
For eCommerce brands, automated email flows (welcome series, abandoned cart, browse abandonment, post-purchase, winback) typically generate 50–70% of total email revenue despite being set up once. Campaign emails (newsletters, promotions, product launches) make up the remaining 30–50% and require ongoing effort.
The highest-performing email programs invest heavily in both. Flows provide consistent baseline revenue, while campaigns drive spikes during promotions, launches, and seasonal events.
How to Improve Your Email Marketing ROI
- Optimize your flows: Your welcome series, abandoned cart, and post-purchase flows should be continuously tested and improved. These are your highest-leverage assets.
- Segment aggressively: Sending the right message to the right person at the right time dramatically improves conversion rates. Segment by purchase history, engagement level, and browsing behavior.
- Clean your list: Remove inactive subscribers regularly. A smaller, engaged list outperforms a large, unengaged one and reduces platform costs.
- Test everything: Subject lines, send times, offers, design layouts, and CTA placement. Even small improvements compound across your entire list.
- Add SMS: Brands using email and SMS together see 15–30% higher revenue from their retention marketing compared to email alone.
What Percentage of Revenue Should Come From Email?
For well-optimized eCommerce brands, email and SMS should drive 25–40% of total revenue. If your email program contributes less than 20%, there is likely significant room for improvement through better flows, segmentation, or send frequency. If it exceeds 50%, you may be over-relying on discounts and should focus on strengthening other acquisition channels.
Frequently Asked Questions
The average email marketing ROI is $36–$42 for every $1 spent. A good ROI depends on your industry, but anything above 20x (2,000%) is considered strong. eCommerce brands with automated flows often see 30–50x returns on their email investment.
Email Marketing ROI = ((Revenue from Email − Total Email Costs) / Total Email Costs) × 100. Total costs include your ESP platform fees, agency or team costs, design tools, and any other email-related expenses.
Include all email-related costs: ESP platform fees (Klaviyo, Mailchimp, etc.), agency or freelancer fees, internal team salary allocation, design and copywriting tools, list building costs, and any SMS costs if using a combined platform.
Well-optimized email and SMS programs typically generate 25–40% of total eCommerce revenue. This includes automated flows (welcome, abandoned cart, post-purchase) which often account for 50–70% of email revenue, plus campaigns for the remainder.
Many brands calculate email and SMS ROI together since they use the same platform (like Klaviyo). This calculator supports including SMS costs and revenue. If you track them separately, just enter email-only figures.
