What's a Good Email Open Rate for Ecommerce Businesses in 2026?

A good email open rate for ecommerce businesses in 2026 is around 31% for one-off campaigns and 42%-plus for automated flows, based on Klaviyo's benchmark data drawn from more than 183,000 ecommerce brands. That campaign-level average pairs with a 1.69% click rate, while flows post a much stronger 5.58% click rate.

Campaigns vs. Flows: Why the Gap Is So Large

The gap between campaign and flow performance isn't small — flows outperform one-off campaigns by roughly 11 points of open rate and more than 3x on click rate. The reason is relevance and timing: a flow email (welcome series, abandoned cart, post-purchase) triggers off something the recipient just did, so it lands when their intent is highest, while a broadcast campaign goes to an entire list regardless of where each person is in their buying journey.

Click Rate Tells the Truthier Story

Open rate for ecommerce, like every industry, is distorted by Apple Mail Privacy Protection, which pre-fetches tracking pixels in the background regardless of whether a person actually opens the email. Click rate and revenue per recipient can't be inflated that way — they require an actual human to click or buy — which is why Klaviyo's own guidance treats those two metrics as the more reliable signal once MPP is accounted for, rather than open rate on its own.

Placed Order Rate: The Metric That Matters Most for Revenue

Beyond opens and clicks, Klaviyo's data shows flows generating a 2.11% placed order rate compared to just 0.16% for campaigns — more than 13 times higher. For an ecommerce brand deciding where to invest limited email marketing time, this is the strongest argument for building out core flows (welcome, abandoned cart, browse abandonment, post-purchase) before investing heavily in one-off campaign sends.

What This Means for Setting Internal Benchmarks

An ecommerce brand sitting well below 31% on campaign opens likely has a list hygiene or sender reputation issue worth investigating before touching subject lines. A brand sitting above 42% on flow opens is in line with a mature, well-targeted flow program — the next lever to pull is click rate and placed order rate, not open rate, since those are harder to inflate and map more directly to revenue. A brand with strong flow opens but a placed order rate well under 2.11% likely has a problem in the offer or the post-click landing experience, not the email itself.

Bottom Line

Benchmark ecommerce campaigns against roughly 31% open / 1.69% click, and flows against roughly 42%-plus open / 5.58% click, but treat click rate and placed order rate as the real scorecard — Apple Mail Privacy Protection makes open rate alone an unreliable way to judge whether an ecommerce email program is actually working.
