E-Commerce: Wine & Spirits
Liquor Royale
Klaviyo case study for an online liquor store: the old setup blasted the whole list every day or two, drew spam complaints above Google's limit and, in our view, brought the domain close to being blacklisted by Gmail and Outlook. We took over in June 2026: open rate 20% to 43%, click rate 2.6x, revenue per recipient 3.6x, spam complaints down almost 90%, and Klaviyo-attributed revenue up every month to a record $53K+ October, $140K+ in five months.
