Klaviyo Email Marketing Stats

As Klaviyo Silver Master certified partners, we track Klaviyo’s performance data closely. These numbers reflect why it’s the dominant platform for ecommerce email marketing.

During Cyber Weekend in 2020, 50,000 of Klaviyo’s customers made over $900 million in sales using channels like email and SMS marketing.

2026 update: Klaviyo’s Cyber Week 2024 performance surpassed previous records. Across ecommerce platforms generally, Cyber Week 2024 drove over $1.2 billion in sales — and Klaviyo’s footprint in that number continues to grow.

On average, brands that switch to Klaviyo enjoy a 46% increase in revenue in just 2 years.

Klaviyo’s abandoned cart flows are among their highest-performing automations. During a 3-month analysis, Klaviyo found their abandoned cart emails had generated over $60 million in revenue for marketers.

Abandoned cart emails recover 3–5% of lost sales on average — and sending 3 emails in a sequence recovers 69% more orders than sending just one. (Klaviyo, 2026)

Email Marketing Statistics – ROI

The ROI case for email marketing is stronger in 2026 than it has ever been — and it compounds when you add automation and personalization.

The average ROI for email marketing in 2026 is between $36 and $42 for every $1 spent. For ecommerce businesses specifically, that figure rises to $45 per dollar for retail and consumer goods — and as high as $72 per dollar for US ecommerce merchants on platforms like Omnisend. (Litmus / DemandSage / Omnisend, 2026)

So it’s no wonder that 59% of marketers say that email marketing is their biggest source of ROI.

Also, according to one study, 60% of customers say that they have made a purchase after receiving a promotional email. The most recent data puts this even higher: nearly 50% of consumers made a purchase directly from an email in the past year. (Omnisend, 2026)

Shoppers are likely to spend up to 138% more when they receive email marketing campaigns.

Email Marketing – Open Rate Stats

Open rates in 2026 require an important caveat: Apple Mail Privacy Protection (MPP) now affects roughly 50–60% of recorded email opens, automatically downloading tracking pixels before a recipient views the email. This inflates open rate data across the industry. Use open rates as a directional signal, not a precise measurement — and lean on click rate and email-attributed revenue as your primary performance benchmarks. (Litmus, 2026)

With that context, the most recent industry-wide open rate data: open rates averaged 30.7% in 2025, up for the fifth consecutive year — a positive directional signal even after MPP adjustments. (Omnisend, 2026)

2026 update: The average email open rate across industries sits between 21% and 25% for human-verified opens (adjusted for Apple MPP). For unadjusted data, averages of 22.7–30.7% are reported across platforms. (Omnisend / Campaign Monitor / searchlab.nl, 2026)

Subject lines with an emoji can improve your email open rates by up to 56% — though this varies significantly by audience demographic and brand. A/B testing subject lines is the most reliable way to know what works for your specific list.

Tuesday is consistently identified as the best day to send emails, with 8AM performing best for open rates. However, Omnisend’s 2026 data found that 8PM was the highest-performing send time for opens — suggesting many users engage with email outside traditional working hours. The right timing for your brand depends on your audience and their daily patterns.

2026 update: In 2025, 55% of email opens occurred on mobile devices — reinforcing the critical importance of mobile-first email design and rendering. (InboxAlly / genesysgrowth, 2026)

Conversion Rate Optimization Stats

Loads of conversions are the ideal outcome for any business. But it’s something that marketers often neglect. For every $92.00 spent on acquiring a customer, most brands only spend $1.00 trying to convert them. No wonder only 22% of business owners and marketers are satisfied with their conversion rates.

However, with the right strategy in place, you could be enjoying some amazing conversion rates. In fact, 74% of content optimization programs have increased sales for businesses.

Using visual elements on a landing page can improve conversions by an enormous 86%. Using a personalized call to action has a 42% higher conversion rate.

Email Content and Design Marketing Statistics

Data shows that the best-performing emails are beautifully designed and well-written — custom-built for the brand, not pulled from a template library.

Good subject lines lead to great results. 47% of people open emails based on the subject line alone. Subject lines with a sense of urgency have a 22% open rate. Emails with personalized subject lines are 26% more likely to be opened and can increase click-through rates by 14% and conversion by up to 10%.

2026 update: AI-generated subject lines now outperform human-written ones by 26% on average for open rates. Combined with dynamic send-time optimization, AI subject line tools can add a further 14% lift. (Litmus / Digital Applied, 2026)

Over 65% of email users say they prefer their emails to contain imagery. 72% of businesses that used GIFs or cinemagraphs noted a higher transaction-to-click rate.

Dark mode continues to grow as an email design consideration. In November 2019, Polar revealed that 95% of people preferred dark mode — and email client dark mode support has expanded significantly since then, making dark mode optimisation a standard part of professional email design in 2026.
