DropUI for SmugMug: sales start with photo viewing
SmugMug does not behave like a regular category store. The client first views a gallery, selects photos, compares prints, packages, and downloads, and only then moves to cart. DropUI should help when intent is already visible: after photo viewing, around Buy Photos, package, coupon, or before checkout.
Gallery, event, package, and coupon
A good scenario focuses on one gallery, event, or shoot type. For an event, remind about a deadline; for a package, explain bundle value; for a download, show the difference from print; for a cart, help finish purchase. The message should answer a specific decision, not promote the whole store.
Do not cover photos without reason
In SmugMug, viewing is the core of selling. A large popup at entry can lower experience quality. A deadline bar, subtle exit intent, pricing embed, or consent-based web push to the same gallery usually fits better.
How to count the result
Measure Buy Photos, package add, print purchase, download selection, coupon use, checkout, or return to gallery. That says more than message impressions alone.
