Case Study: Mini Katana Reactivates Email Subscribers with PostPilot

Mini Katana Activates AWOL Email Subscribers with PostPilot

Mini Katana, the replica Japanese sword brand, grew rapidly through viral TikTok and YouTube content, building an email list of more than 500,000 subscribers in just six months. But with conversion rates below 1% and low email engagement, the team needed a way to re-engage subscribers who weren’t opening their marketing emails.

Using PostPilot’s MailMatch feature, Mini Katana matched email subscribers to physical addresses and sent branded postcards with a discount offer to drive purchases. PostPilot’s direct mail program delivered strong performance, including 5x-plus ROAS for the ongoing subscriber campaign, 9x ROAS for a winback flow, and an 8.3x ROAS on abandoned cart campaigns, helping Mini Katana turn otherwise unreachable prospects into customers.
