How Much Revenue Are Your Flows Leaving on the Table?
Quantify the revenue your missing email and SMS flows are giving away every month, and which flows to build first.
| Welcome series | $0 |
| Abandoned checkout | $0 |
| Browse abandonment | $0 |
| Post-purchase | $0 |
| Winback | $0 |
Well-run email and SMS flows drive around 30% of ecommerce revenue. Most stores without a full flow stack sit at 10 to 20%.
How the email revenue calculator works
The fastest money in ecommerce is the revenue your automated flows should be capturing but are not. We size that gap against the benchmark and split it across the flows you are missing.
The formula
Current email revenue = monthly revenue x your current email share. The benchmark is the same revenue x 30%. The gap between them is what you are leaving on the table. We annualize it and allocate it across the five core flows by their typical contribution.
The flows that close the gap
Welcome, abandoned checkout, browse abandonment, post-purchase, and winback. Flows earn far more per send than campaigns, so the gap is almost always missing or weak automations, not more blasts. A stronger LTV from retention also makes your paid acquisition math work.
Frequently asked questions
What percentage of ecommerce revenue should email and SMS drive?
Well-run owned flows typically drive around 30% of total revenue, sometimes 30 to 40% for mature setups. Stores using email only for occasional blasts usually sit at 10 to 20%.
Which email flows make the most money?
The welcome series and abandoned-checkout flow are usually the top earners, followed by post-purchase, browse abandonment, and winback. Flows generate far more revenue per recipient than one-off campaigns.
Is this estimate realistic?
It is a directional gap-to-benchmark estimate. Your actual recoverable revenue depends on traffic quality, list size, and offer. It is meant to size the opportunity, not promise an exact figure.
Does this work for Klaviyo specifically?
Yes. The benchmarks come from Klaviyo and broad ecommerce data, and the five flows map directly to a standard Klaviyo flow stack.
