Klaviyo campaign data, last 3 months baseline comparison + individual campaign tests
Limited Drops Lost in the Promotions Tab
100 Thieves runs limited-edition apparel drops that sell out fast. But their emails were landing in Gmail's Promotions tab, meaning fans missed drop announcements and lookbook campaigns that drive immediate purchases.
Primary Inbox Placement for Every Drop
Mailtail generates unique code for each merchant that Gmail can't pattern-match as promotional. 100 Thieves integrated in minutes and immediately saw their emails landing in Primary.
