Case Study: Mailbird (email software company) achieves 102% year-over-year growth with FastSpring

Mailbird achieved their goal of 100% revenue growth with the support of FastSpring’s full-service ecommerce platform

Mailbird, a Palo Alto–based maker of an easy-to-use Windows email client, needed a flexible, all‑inclusive ecommerce solution as it scaled. The team required support for multi‑tier subscriptions, one‑time payments, global payments and VAT/taxes, plus a branded, seamless checkout and the ability to run market-specific A/B tests to optimize pricing and conversions.

Partnering with FastSpring’s full‑service platform—providing tax/VAT handling, subscription management, global payment processing, upsells/cross‑sells and customizable branded checkouts—enabled Mailbird to test pricing by market, streamline purchase flows, and focus on product development. The result was strong business growth: 102% year‑over‑year revenue growth while improving conversion optimization and international reach.
