Ecommerce Email Marketing Benchmarks: What Is Actually Good in 2026?

Email marketing benchmarks are useful for answering:

"Are we broadly in the right range?"

They are much less useful for answering:

"Is our retention program actually working?"

Two ecommerce brands can have the same open rate and completely different margins, average order values, buying cycles, customer LTV, repeat purchase behavior, attribution models and product categories.

So use industry benchmarks as context. Then judge your program primarily against your own historical performance and customer behavior.

2026 Ecommerce Email Benchmarks at a Glance

Omnisend's current 2026 benchmark report is based on more than 20 billion campaign emails sent by more than 27,000 brands during 2025. Its cross-industry campaign averages were:

These are not Magicianly benchmarks. They are one vendor dataset with one methodology.

Campaign Benchmarks vs Automation Benchmarks

This is where the comparison gets much more interesting. In the same Omnisend dataset:

Automations produced substantially more value per email because they were triggered around customer behavior and intent. That is an important lesson.

Timing and relevance often matter more than sending volume.

Klaviyo's current 2026 benchmark dataset tells a similar directional story. Across more than 183,000 Klaviyo customers, Klaviyo reports that:

• campaigns account for roughly 94.7% of email send volume
• flows account for roughly 5.3%
• flows generate nearly 41% of total email revenue
• average flow click rate is approximately 5.58%
• average campaign click rate is approximately 1.69%
• flow placed-order rates are roughly 13 times higher than campaign rates

Do not combine Klaviyo and Omnisend data into one "industry average." Their methodologies and customer populations differ.

Why Open Rate Is a Weak Primary Benchmark

Open rate is useful. It can help diagnose:

• subject line
• sender recognition
• audience engagement
• inbox placement
• campaign relevance

But open tracking is imperfect. Apple Mail Privacy Protection can preload tracking pixels and make some messages appear opened even when the recipient did not intentionally open them. So:

Open rate should start the investigation, not end it.

Click Rate Is Usually More Actionable

A click requires the recipient to take a clearer action. It tells you more about:

• content
• product relevance
• offer
• CTA
• email structure

A brand with lower opens but stronger click and conversion can have a healthier campaign than a brand optimizing purely for opens.

Conversion Rate Depends Heavily on Category

Omnisend's 2025 campaign dataset illustrates why universal benchmarks are dangerous. For example:

• Food & Drink campaign conversion: approximately 0.15%
• Health: approximately 0.12%
• Beauty & Fitness: approximately 0.07%
• Apparel: approximately 0.05%
• Home & Garden: approximately 0.04%

Do not conclude:

Our apparel emails are bad because a food brand converts three times higher.

Customer behavior is different. Purchase friction is different. AOV is different. The purchase cycle is different.

Automation Type Matters Too

The same dataset showed very different outcomes by automation type.

These numbers should not become goals. A back-in-stock automation naturally reaches someone who already demonstrated product interest. A reactivation email reaches somebody who is disengaged. Those customers have completely different intent.

The Benchmark Most Brands Forget: Their Own Previous Performance

Before comparing yourself with 27,000 other brands, compare this quarter vs last quarter.

• click rate
• revenue per recipient
• conversion
• unsubscribe rate
• deliverability
• signup conversion
• first-to-second purchase rate
• 30-day LTV
• 60-day LTV
• 90-day LTV

If the business is improving consistently, that matters.

Email Revenue Percentage Is Not a Reliable Benchmark by Itself

You may hear:

Email should drive 30% of revenue.

We do not like using that as a universal goal. Why? Because a high email-attributed revenue percentage can mean:

• email is excellent
• organic repeat purchase is high
• attribution is generous
• paid acquisition is weak
• customers were buying anyway

A low percentage can also happen in a healthy business with:

• high AOV
• long purchase cycles
• heavy retail revenue
• strong acquisition growth

Context matters.

Benchmark Against Customer Behavior

For established ecommerce brands, we care much more about whether retention activity improves customer behavior.

Subscriber to customer conversion

Are more subscribers becoming buyers?

First-to-second purchase rate

Are more first-time customers becoming repeat customers?

Time between orders

Are customers coming back faster?

30, 60 and 90-day LTV

Are newer customer cohorts becoming more valuable?

Repeat revenue

Is more revenue coming from returning customers?

Subscription churn

If relevant, are subscription cohorts staying longer?

We covered that scorecard in detail in ecommerce retention metrics.

Benchmark Campaigns Against Campaigns

Do not compare campaign conversion with abandoned-cart conversion. One is proactive marketing. One reaches somebody who just demonstrated buying intent. Useful comparisons are:

• campaign vs previous campaign type
• welcome flow vs previous welcome version
• cart flow vs previous cart flow
• engaged segment vs engaged segment
• same season year over year

Compare like with like.

Benchmark Segments Separately

A campaign sent to your most engaged 30-day audience should not perform like a campaign sent to a 180-day re-engagement audience. That is expected.

Segment-level benchmarks help explain:

• audience quality
• frequency
• deliverability
• customer intent

Our approach to building those audiences is in Klaviyo segmentation strategy.

Benchmark Before and After Major Changes

When you change:

• signup form
• campaign cadence
• segmentation
• flow structure
• deliverability strategy
• offer
• product merchandising

capture the baseline. Otherwise six months later you will remember:

I think it improved.

instead of knowing.

Our Benchmark Hierarchy

We use benchmarks in roughly this order.

1. Own historical performance

Did the program improve?

2. Comparable customer segment

Are we comparing similar people?

3. Comparable message type

Campaign vs campaign. Flow vs equivalent flow.

4. Industry benchmark

Are we broadly outside normal ranges?

5. Platform-wide benchmark

Useful context, but furthest from your specific business.

When a Benchmark Should Trigger Investigation

Open rate falls sharply

Investigate deliverability, audience, sender, frequency and content fatigue. Start with Klaviyo email deliverability.

Click rate falls

Investigate email content, CTA, offer, design and product relevance.

Unsubscribe rate rises

Investigate frequency, relevance, promotional pressure and segmentation. See email fatigue and frequency.

Flow conversion falls

Investigate trigger, timing, customer state, offer and competing messages.

Retention metrics stay flat

Investigate the strategy, not just email creative.

Our Verdict

Benchmarks are useful for perspective. They are dangerous when they become the goal.

A brand with:

• average open rates
• improving repeat purchase
• better customer LTV
• stronger margins

can be healthier than one with a beautiful 50% open rate and stagnant customer economics.

Use industry data to ask better questions. Then optimize the business you actually operate, using the wider email and SMS retention system.
