The price drop flow that tells the people who were already watching

Something they were weighing up just got cheaper. The build is all in the rules that hold it back.

How we build it

One watched item, one price change, and the rails that hold it

It runs off your price book as well as your catalogue, so we build it account by account.

Who it can reach

The people who already looked at it

Nobody signs up for this one. You're in it because you viewed that item or saved it, recently.

Trigger

The price on that item moves down

The flow watches your product feed, not a calendar. The event is a price that falls and stays down long enough to be a decision, not a mistake.

The guard rails

Four rules that decide whether it sends at all

This is the build. An alert with nothing holding it back is a discount tap left running.

A floor under the dropThe cut has to be worth an email. We set the floor against your margin and your own price history.
Lines that never fireCore products, new season stock, anything already booked into the campaign calendar. Excluded up front.
A cap on the personOne of these inside a set window, however many saved items move. Without it a wish list becomes a drip of discounts.
A window on the interestA view from months ago is history, not interest. Past the window the profile drops out and hears nothing.
Decision

Is the line on the exclusion list?

YesExit, no emailNoContinue to the cap

Read at send time, not at build time: the list changes whenever a promotion gets planned.

Decision

Have they had one of these lately?

YesHold until the cap clearsNoContinue to the send

The cap is what separates a useful alert from a discount habit. It counts on the person, not the product.

Email one

One item, the new price, and nothing else

Subject line · The one you were looking at costs less today

No code, no countdown, no second product. The news is the price, the link opens that item, and the send is short enough to read on a lock screen.

Decision

Is it still cheaper, and is it still there?

NoClose the flowYesContinue to email two

The check most builds skip. A reminder pointing at a price that's gone back up costs you more than the order was worth.

Email two

The reminder, while both are still true

Subject line · Still down, still here

The same item at the same price, said once more. Two sends is the whole flow: a third is a campaign nobody asked for.

Exit

The price goes back up

The flow closes and nobody hears a thing. That's the point of it.

The delay is a starting point. The interest signal is the one browse abandonment runs on, so the two share an exclusion list. Subject lines are drafts.

The difference

Why this isn't a sale campaign with a smaller list

One goes out on a date you picked. The other on the day the price moved.

The campaign

A date you chose, and everybody hears it

  • You pick the day, so the deadline does the arguing.
  • It reaches the people who would have paid full price as well.
  • It moves stock and makes the month. It lives in the calendar.
The flow

The day the price moved, and one person hears it

  • The price picks the day, so there's no countdown.
  • It goes to somebody who looked at that item, and nobody else.
  • It closes a decision that was left open. It lives in the flow stack.

Run both. The exclusion list keeps them apart.

The pair

The other half of the same shelf

A shopper walks away for two reasons: it's gone, or today it costs too much. The restock alert answers the first. This one answers the second.

Success stories

Where the flow revenue is published

Three programmes that report revenue flow by flow.

Revenue is the wrong reading here

A discount flow can lift revenue and cost you money in the same quarter. So we hold the build to these four, in your account, against its own history.

RevenueRevenue per recipient, against an ordinary campaign
MarginMargin per order, not revenue per order
Full priceFull price orders on the same lines
HabitHow much of the audience buys only on a cut
The trigger and the rails
What is a price drop flow?

A price drop flow is an automated email that goes to one person when the price of something they viewed or saved falls. The price change is the trigger, not a date, so nobody outside that audience hears about it.

What triggers a price drop email?

A price change on a product in your feed, matched against the people who showed interest in it inside a set window. We read the price again at send time, so a cut that's been reversed never reaches anybody.

How big does the drop have to be before it sends?

Big enough that a shopper would notice it on the page. We set that floor against your own margin and price history instead of a fixed percentage: a cut that matters on a considered purchase is noise on a consumable.

Discounting, margin and the calendar
Will a price drop flow train people to wait for a discount?

It will, if you run it with nothing holding it back. Three things stop that: a cap on how often one person can get it, an exclusion list that keeps your core lines out, and a floor under the size of the drop.

How is a price drop flow different from a sale campaign?

A sale campaign is a date you choose, sent to a list with a deadline attached. A price drop flow is one message to one person about one item they already looked at, on the day the price moved. No code, no countdown.

Which products should never be in a price drop flow?

Core lines you don't discount, anything booked into the campaign calendar, and new season stock still selling at full price. Naming them is the first job.

Shall we look at what your price changes already do?

Bring your Klaviyo login and the lines you discount most often. We'll count how many people are sitting on a saved item, and tell you whether an alert is worth building at all.
