The premium nicotine pouch brand lifted email open rates by 62% and drove 51% more revenue per send with Mailtail.
Klaviyo personalized-content A/B test, 100% test size across 210K+ recipients (May 2026)
Sale Emails Buried in the Promotions Tab
ALP Pouches sends high-volume promotional campaigns to a list of 100K+ subscribers. But with a heavily commercial, discount-driven message, their sale emails were consistently filtered into Gmail's Promotions tab — capping open rates at the low 20s and leaving revenue on the table on every send.
Primary Inbox Placement on Every Sale Send
Mailtail generates unique code for each merchant that Gmail can't pattern-match as promotional. ALP Pouches ran a head-to-head A/B test on their Memorial Day Sale — identical subject line, preview, and creative — with Mailtail applied only to the variant. The Mailtail version won across every metric.
