Campaign vs flow revenue split: what is actually normal?
Should your one-off campaigns or your automated flows be driving more of your email revenue? Here is a grounded benchmark from the brands we audit, set next to Klaviyo's published data, the sends-versus-revenue leverage most stores miss, and how to read your own split to find the revenue you are not capturing.
Roughly 60 percent campaigns, 40 percent flows
Across the direct-to-consumer brands we have audited, email revenue split at a median of about 61 percent from campaigns and 39 percent from flows. That is a small sample, so treat it as directional, but it matches Klaviyo's published benchmark almost exactly, roughly 59 percent campaigns and 41 percent flows. So a split near 60/40 is normal and healthy. It is not a 50/50 target you are failing to hit, and it is not a sign that flows are underperforming. Campaigns lead total email revenue in nearly every dataset, for one simple reason we will get to next.
Flows are a few percent of sends and about 40 percent of revenue
Campaigns lead on total revenue because they go to far more people. But look at it per send and the picture flips. In Klaviyo's published data, automated flows are only a few percent of all the emails a store sends, yet they drive roughly 40 percent of email revenue. That means a single flow send earns many times what a campaign send does, because it reaches someone at a moment of real intent: they just browsed, abandoned a cart, or are due to reorder. That is the whole case for flows. Not that they should out-total campaigns, but that they are your highest-efficiency revenue, so any gap in them is expensive.
Read your flow share against these bands
The split matters most as a signal of where the work is. Here is how to read your flow share of email revenue.
| Flow share of email revenue | What it usually means |
|---|---|
| Flows under ~30% Flow gaps | Almost always a missing or half-built core flow: browse or checkout recovery, post-purchase, win-back. The most common and most recoverable gap an audit finds. |
| Flows ~30% to 45% Healthy | Where most well-run programs sit. Our audited-brand median (about 39%) and Klaviyo's published average (about 41%) both land in this band. Campaigns lead, flows pull their weight. |
| Flows over ~45% Check your campaigns | Flows outrunning campaigns usually means campaigns are under-sent, not that flows are superhuman. Often a sign there is untapped campaign revenue, not a flow to celebrate. |
These are attributed figures
The splits here, ours and Klaviyo's, come from email-attributed revenue: the orders an email platform credits to a campaign or a flow within its attribution window. They are a reliable way to compare the two channels against each other, but attributed totals overlap with other channels and are not the same as incremental lift. Read the split as a directional health signal, not a precise measure. For the fuller picture of attribution, see attributed vs incremental revenue.
The only split that counts is yours
A benchmark tells you whether your split is normal; it cannot tell you which flow is missing or which campaign is under-sent. That is specific to your account. A free Klaviyo audit breaks down your campaign and flow revenue, shows your split against a healthy range, and pinpoints the flows that are under-earning or absent, ranked by the revenue a more complete set would add. So you know exactly where the next dollar is, not just how you compare.
Is it safe to connect Klaviyo?
- Read-only. It can read your campaign and flow performance. It cannot send, edit, or delete anything in your account.
- No customer data stored. It works from your metrics, not your subscriber list. Names, emails, and phone numbers are never stored.
- Nothing ships without you. Built emails land as drafts for your review; nothing is pushed to Klaviyo on its own.
- Built by an operator. David Refaeli-Berman ran enterprise email at Chewy, Amazon, Overstock, and Bed Bath & Beyond.
Questions
What is a normal campaign vs flow revenue split?
For most direct-to-consumer stores, campaigns drive a bit more email revenue than flows, in the neighborhood of 60 percent campaigns to 40 percent flows. Across the brands we have audited the median was about 61 percent campaigns and 39 percent flows, which matches Klaviyo's published benchmark of roughly 59 percent campaigns and 41 percent flows. The exact split varies widely by store, so treat these as directional.
Should flows drive more revenue than campaigns?
Usually not, and that is fine. In nearly every published dataset campaigns drive the larger share of total email revenue, simply because they go to far more people. Flows leading campaigns is uncommon and often means a store is under-sending campaigns rather than over-performing on flows. The goal is not to flip the ratio but to make sure flows are pulling their weight.
Why do flows matter if they are the smaller share?
Because of leverage. Automated flows are a small slice of the emails you send, on the order of a few percent, yet they drive roughly 40 percent of email revenue. That means each flow send earns many times what a campaign send does. A store with weak or missing flows is leaving its highest-efficiency revenue on the table, which is why underbuilt flows are so often the biggest gap an audit finds.
What if flows are a tiny share of my email revenue?
If flows are well under about 30 percent of your email revenue, you most likely have gaps in the core flow set: a missing browse or checkout recovery, no post-purchase or win-back, or flows that were switched on but never built out. That is a common and very recoverable finding, because adding one strong flow can move the whole split.
How do I find my own campaign vs flow split?
Your email platform reports revenue for campaigns and for flows separately; divide each by their combined total to get the split over a period. A free audit does this for you and goes further, showing which specific flows are under-earning and estimating the revenue a more complete flow set would add.
