Ecommerce Email Automation Statistics: Flows vs. Campaigns

Selected article findings, not the complete article.

In Omnisend’s 2026 report on 2025 activity, automated emails accounted for 2% of sends and 30% of email-attributed revenue. That is a 28-percentage-point gap between their send share and their revenue share. The percentages use different totals. The gap describes concentration of credited revenue.

Klaviyo reported an average open rate of 32.2% for flows and 31.0% for campaigns, a gap of 1.2 percentage points. Apple Mail Privacy Protection can hide actual reading activity from senders. A recorded open can include automatic activity.

In Omnisend’s 27,000-plus-brand benchmark, restock emails converted at 6.72%, compared with 1.72% for abandoned cart emails. The difference was 5.00 percentage points. Only 0.6% of brands in this dataset used restock email. Trigger eligibility and audience intent differ.

Klaviyo’s 2026 cart study reported $6.77 in average revenue per recipient and $13.70 for the top 10% of abandoned cart email performers. That is a difference of $6.93 per recipient in the study. The comparison is between the reported average and the top-performing group. It is a revenue benchmark, not a margin benchmark.
