As per studies done by Shopify, a whopping 87% of marketing leaders consider email marketing essential to their company’s success. Moreover, 52% of email professionals saw their campaign ROI double between 2022 and 2023. These statistics prove the unparalleled potential of email marketing.
In this blog, we’ll dive into the factors that make email marketing so impactful, explore the key metrics to track ROI and discuss how to calculate it using real data. Finally, we’ll share strategies to maximize your returns in 2025 and beyond.
Email ROI statistics across industries
According to the Litmus survey, email marketing delivers an impressive ROI, with an average of $36 earned for every $1 spent which is 3,500% ROI. Some studies have reported even higher numbers, reaching up to $44 for every $1 spent, outshining every other marketing channel.
Even in industries with the lowest ROI, such as media, publishing, events, sports, and entertainment, the return is still impressive at 3200%. But these figures aren’t just theoretical. They highlight how businesses, when equipped with the right strategies, can achieve tangible and exceptional results.
How does Email marketing deliver such high ROI?
Email marketing’s dominance lies in its cost efficiency, scalability, and ability to engage audiences effectively. Here’s why it delivers such impressive returns:
1. Low cost, high reach
Email marketing offers an affordable way to connect with your audience. Unlike traditional media like TV or print ads, it requires minimal upfront investment. It also scales easily, enabling businesses to grow their reach without incurring significant additional costs.
2. Segmentation and personalization
Research shows that segmented campaigns drive 760% more revenue, and personalized subject lines increase open rates by 26%. Reaching the right audience with tailored, relevant content drives engagement and higher conversions.
3. Automation and consistency
Automation reduces manual effort while ensuring consistent, personalized communication. Automated workflows like welcome emails or abandoned cart reminders streamline customer journeys, improving lifetime value and overall ROI.
4. Customer retention
Retaining customers is far more cost-effective than acquiring new ones. Regular email communication keeps your brand top of mind, fostering loyalty. Studies show repeat customers spend 67% more than new ones, underscoring the importance of email as a retention tool.
5. Measurability and optimization
Email marketing allows businesses to test, measure, and refine campaigns in real time. With tools like A/B testing and detailed performance analytics, marketers can make data-driven improvements to maximize results.
Key metrics to track email ROI
Measuring ROI isn’t just about tracking revenue, it’s about understanding the factors driving it.
- Open rate
The percentage of recipients who open your email
- Click-through rate (CTR)
The percentage of recipients who click on links in your email
- Conversion rate
The percentage of recipients who complete a desired action, such as making a purchase
- Bounce rate
The percentage of emails that fail to reach recipients’ inboxes
Tip: Bounce rate affects deliverability. Ensure that the contact list is refined regularly and that sending IP addresses and domains have good reputations and aren’t flagged as spam.
