Show repeat buyers the size they should be on.
A customer reorders the same product, month after month, in the smallest size you sell. An upsell flow shows them the bigger size or the bundle at the moment it makes sense - with plain math instead of pressure.
Upsell
An upsell flow offers a customer a bigger size or a bundle when their order history says it would genuinely serve them - the shopper reordering a 30-day jar every month is a 90-day customer who has not noticed yet. The pitch is arithmetic, not pressure: the larger size costs less per day and removes the gap days between orders. Our team builds the flow in your brand voice and runs it in your Klaviyo, targets it only at orders where the upgrade actually fits, and keeps the math honest. You approve every email, we ship.
Fires when an order comes in where a bigger size or bundle fits - typically a repeat purchase of a product you also sell in a larger format. The email lands after the order, not during checkout, so it reads as useful advice rather than a pop-up.

Lead with the math
Cost per day, cost per serving, dollars saved over the quarter. If the bigger size is genuinely the better deal, the numbers make the case better than any adjective could.
Solve the gap days
Anyone reordering monthly has run out before the next jar arrived. The bigger size is not just cheaper - it means they never skip a day waiting on shipping.
Wait for the pattern
One purchase is a trial. A reorder is a habit. Send the upgrade when the order history shows they will actually use the larger size, not on the first purchase.
Leave the countdown out
There is no scarcity here and no deadline, so do not invent one. A calm, factual offer can sit in the inbox until the next reorder, and it will still be true.
Questions about this flow.
Who gets the upsell email?
Customers whose order makes a bigger size or bundle a genuine fit - most often someone reordering a product you also sell in a larger format. Our team sets the rules in your Klaviyo so the offer only goes where the math actually works, and you review the targeting before anything sends.
Does an upsell email feel pushy?
Not when it is framed as arithmetic. The email shows what the customer already spends, what the larger size costs, and what they keep - no countdowns, no invented urgency. You approve the copy before it goes live, so the tone stays yours.
Why two emails instead of one?
The first email makes the case with the math. The second arrives closer to their usual reorder time, when the decision is live anyway. Our team builds the timing around real purchase patterns and runs the sequence in your Klaviyo.
