Upsell Popups
One offer, at the two moments a shopper actually acts — the add to cart, and the click on Proceed to checkout.
Built for WordPress · WooCommerce
LUMÉ is a demo store — its numbers are illustrative.
▲ +20% conversions** Industry benchmarks and vendor-observed averages for popup offers of this type — not a guarantee. Your results depend on catalogue, traffic and how relevant the offer is; the SalesMax dashboard shows your real numbers per booster within days.
Scene 3 of 6 in the shopper journey: the product page — the booster fires on Add to cart, which happens on single product and archive pages alike. In its demo the offer lands after the checkout click and takes a $91 cart to $135.
Product Add-OnsTriggers
No placement picker is documented, and none is needed. In the plugin it is SalesMax → Sales Boosters → + New Booster → Boost Popups.
Click a trigger — the preview swaps to the page it fires on.
Both triggers can be used independently or combined for layered targeting — one booster campaign can answer the add to cart, the checkout click, or both.
Popup shows to
All products, specific products or specific categories — the setting decides which product interactions are allowed to trigger the popup.
Product suggestion method works based on
Cart products bases the suggestions on all current cart items; Added product (recently) bases them on the most recently added one.
What the hero demo is running
This trigger: the cart is complete, the shopper presses the button, and one relevant offer answers the press. Nothing appears until they act.
Where the products come from
Related, cross-sell, upsell or a hand-picked set — the booster-level product source, set once per campaign. See the control room below.
We are naming the limit rather than hiding it, because the limit is the point: this popup is caused, never thrown. It answers something the shopper just did instead of interrupting them mid-browse. The documentation for Boost Popups lists no other trigger, so none is claimed here:
Wireframe preview, LUMÉ demo store — the trigger names are the plugin’
Templates & appearance
Minimal or Colorful, vertical or horizontal — the four documented layouts, every label yours to type.
The math
Paid for in moments, not impressions — it shows only on add to cart or checkout. Say 4,000 popups, 4% taken, an offer worth $34: 4% × $34 × 4,000 = +$5,440/mo. Press the keys.
The control room
Deliberately short — everything on this panel is documented; nothing here is inferred.
Tap the chips — the rule sentence rewrites itself.
The docs put this last one in SalesMax’s general settings rather than on the campaign panel.
WooCommerce’s own related products, related by shared tags or categories — nothing to maintain.
The cross-sells you already picked under Linked Products on the product itself.
The upsells from the same Linked Products panel — the step-up version of what they are buying.
Hand-pick the set with the product search when you know exactly what should be offered.
This booster-level source is separate from the add-to-cart trigger’s cart products vs added product setting. The docs describe them as separate controls and never state how they resolve against each other, so we don’t either.
A fixed amount off each product (the docs’ own example: “each add-on gets $3 off”) or a percentage off each item individually (“20% off each item”). Or none at all — the products show at their regular price.
A Free (100% off) type is listed, but the docs asterisk it and note that available discount options may vary by booster type, so we can’t confirm it is selectable on this one. Treat it as check-before-you-plan.
If a product already carries a sale price you can optionally keep it out of the extra discount. The docs describe this one under SalesMax’s general settings, not as a per-campaign field.
Business hours (e.g. 9:00 AM – 6:00 PM), a condition on a category being purchased, and user roles (e.g. logged-in customers). These are the examples the documentation gives — and it says most boosters support conditional visibility, so confirm on your build before you design a campaign around one.
Pick the day the booster activates and the day it deactivates itself. Day granularity — the docs say “select the day”, not the time.
No AND/OR rule groups, no condition sets and no negation: the docs never state how multiple conditions combine, so we won’t draw you a logic diagram. No cart-total threshold, no geo or country rule, no device rule, and no new-versus-returning customer rule — none of them is a documented field for this booster.
FAQ
No. Popups are injected dynamically after page load and do not block core content.
Absolutely. Create separate booster campaigns with different targeting rules and designs.
The popup is displayed dynamically when a customer interacts with your store, based on the selected trigger settings. It works across all pages and themes, and it needs no page reload and no redirect to appear.
Yes. Use the “After product added to cart” trigger option. You can narrow it to all products, specific products or specific categories, and decide whether the suggestions are based on all current cart items or only on the most recently added product.
Confirm the booster is enabled in the dashboard, check that the triggers are set correctly, verify your display conditions, check that the selected products are published and in stock, and temporarily disable caching or popup-blocking extensions while you are testing.
Works well with
The popup answers an action. The row starts with the boosters that give the shopper a reason to act in the first place, then runs through the rest of the suite.

Upsell Popups
The best moment to offer something is the second after a shopper acted. Answer it — and every other booster in the suite with it, on every plan, no feature gating, ever.
