Reading your Gap Check

Updated October 17, 2026. This page describes exactly what the Gap Check calculates today, including what it does not do.

What goes in

For each of four email flows (abandoned cart, welcome, browse abandonment and post-purchase) you enter two numbers from Klaviyo: revenue per recipient (RPR) and recipients per month. Where to find them. We do not connect to your Klaviyo account or check the numbers; the result is only as good as what you type.

Each flow is compared with Klaviyo's published 2026 email benchmarks:

Flow	Average RPR	Top 10% RPR
Abandoned cart	$6.77	$13.70
Welcome	$5.75	$13.27
Browse abandonment	$2.08	$4.32
Post-purchase	$1.80	$2.77

Source: Klaviyo, 2026 abandoned cart benchmarks report (more than 110,000 Klaviyo customers).

What each band means

Band	Rule (your RPR for that flow)	What it suggests
Excellent	At or above the top 10% figure	No fix suggested. Keep an eye on it monthly.
Good	At or above the average, below the top 10%	Working. Test a stronger first email before rebuilding anything.
Fair	At least half the average, below the average	Earning less than a typical Klaviyo flow. Worth a rebuild.
Poor	Below half the average	Something is likely broken or missing: timing, filters, content or the trigger.
Not entered	Left blank, not a number, or negative	Treated as a missing flow.

For example, for abandoned cart: $13.70 or more is Excellent, $6.77 up to $13.70 is Good, $3.385 up to $6.77 is Fair, and under $3.385 is Poor.

These bands are our own rule. Klaviyo's Benchmarks page also uses the words Poor, Fair, Good and Excellent, but it rates you against a group of peer companies, so it can show a different band for the same number. See What Poor or Fair means in Klaviyo Benchmarks.

How the dollar gap is worked out

Per flow: gap per recipient = the average RPR minus your RPR, or zero if you are at or above the average.

Monthly gap for that flow = gap per recipient x your recipients per month, rounded to whole dollars.

Estimated monthly gap = the sum over the flows you entered.

Example: abandoned cart RPR $2.10 with 400 recipients a month. Gap per recipient is $6.77 minus $2.10, which is $4.67. Monthly gap is $4.67 x 400, about $1,868.

Things the number deliberately does not do:

It measures against the average, not the top 10%. A flow in the Good or Excellent band adds $0, even though top stores earn more.
Missing flows add $0. A blank row has no recipients to multiply, so it is not in the dollar total, even though a missing flow can be the biggest opportunity. It still shows up in your top 3 fixes.
No recipients means $0. If you enter an RPR but leave recipients blank, that flow's gap is $0. Enter both numbers.
Flows above average do not offset flows below it. Each flow's gap is zero or more.

How the top 3 fixes are chosen

Poor and Fair flows first, largest monthly gap first.
Then missing flows, the one with the highest average benchmark first (abandoned cart, then welcome, browse abandonment, post-purchase).
Then Good flows, furthest from the top 10% first.

Excellent flows never appear. If all four flows are entered and all are Excellent, the result says there are no urgent fixes. Only the first three are shown.

Limits you should know

It is an estimate, not a revenue promise. Closing a gap to the average is not guaranteed, and we have no customer results of our own yet.
Your order value matters a lot. RPR rises with average order value. Klaviyo's own reference table for abandoned cart flows, in one revenue band, runs from $0.13 to $0.81 (25th to 75th percentile) for orders under $28 and from $7.77 to $43.51 for orders over $291 (Benchmarks for flow emails reference). A low priced store can be healthy below our average, and a high priced store can be weak above it.
Industry and size are ignored. The benchmark is one average across Klaviyo customers.
Email only. Text message flows and win-back are not included.
Date range and attribution are yours. Use the last 30 days for both numbers so they match. Klaviyo attributes revenue using your account's attribution settings, and we take the number as you enter it.
Benchmarks change. We use Klaviyo's 2026 published figures and will update them when Klaviyo publishes new ones.

Your saved result and dashboard

Every completed Gap Check gets a saved result link (flowsfixed.com/r/ followed by a long random code) with the bands and top 3 fixes. Anyone with the link can see it, and it is hidden from search engines. If you entered your email, you can sign in to see all your saved results in one place. The dashboard also has before-and-after slots (baseline, day 14 and day 30) for flows we fix; until then they say "Not yet measured".
