Email marketing is like the Swiss Army knife of digital marketing: versatile, reliable, and still crazy effective in 2025. With 4.6 billion people using email worldwide and billions of messages sent every day, it’s a channel that just keeps delivering. I’ve pulled together the latest email marketing ROI statistics to show you what’s working, from open rates to revenue, plus some practical tips to get more out of your campaigns. And because I couldn’t resist, I’ve thrown in a few cool email facts to spice things up.
What’s Email Marketing ROI, Anyway?
At its core, ROI in email marketing is about figuring out if the money you’re spending on emails is coming back to you—and then some. It’s a simple way to see if your campaigns are worth the effort. Here’s the math:
ROI = (Revenue – Cost) ÷ Cost × 100
Let’s say you drop $200 on a campaign, including design, tools, and your team’s time, and it brings in $1,000 in sales. Plug it in:
($1,000 – $200) ÷ $200 × 100 = 400%
That’s $4 for every $1 you spent. Not too shabby! Tracking the ROI on email marketing lets you know where to put your budget, how to tweak your messages, and what goals to aim for.
Email Open Rates in 2025: Who’s Opening What?
Open rates are your first clue about how well your emails are performing. They show how many people bother to open them. In 2025, the average open rate across industries is about 20–25%, but it can vary a lot depending on your industry, the quality of your email list, and how well your content resonates.
How Different Industries Stack Up
- Retail: 25-30% open rates, fueled by tempting sales and promos.
- Education: 30-35%, thanks to emails keeping students and staff connected.
- Tech: 20-22%, where you’ve got to be super targeted to cut through the noise.
The Power of Personalization
Personalized emails, like ones that use someone’s name in the subject line or match their interests, can boost open rates by 5-10%. A subject line like “Hey Lisa, Your Exclusive Deal Awaits!” might increase opens by 10-14%. Timing’s a big deal too: emails sent on Tuesdays between 9 AM and noon EST tend to get the best email engagement rates. It’s all about hitting the inbox when people are looking.

Five Tricks to Supercharge Your Email ROI

Make Emails Phone-Friendly
Since 55% of emails are opened on phones, your emails need to look awesome on small screens. Use clean designs, big fonts, and easy-to-tap buttons to boost clicks by 15%. Quick note: Apple’s email app has the biggest email client market share, with Gmail hot on its heels.
Keep Your List Squeaky Clean
A messy email list can mess up your deliverability. Regularly ditch inactive subscribers or bad addresses to keep bounce rates low. Forget about buying email lists for purchase organic lists always performs better.
