Case Study: Scribd achieves global reader engagement and scalable, reliable email delivery with Mailgun

Scribd partners with Iterable + Mailgun to engage readers around the globe

Scribd, the subscription reading service with more than 100 million monthly visitors and a digital library of over 1 million titles, depends on email for acquisition, engagement and lifecycle management. As its product and global subscriber base grew, Scribd outgrew its legacy martech and needed scalable, reliable delivery plus more personalized, data-driven messaging from a trusted partner to reduce churn and grow paid subscriptions.

Scribd partnered with Iterable and Mailgun by Sinch to migrate workflows, warm up 11 IPs, and scale to about 1 million marketing and transactional sends per day (plus 10–20 million broadcast messages monthly). The switch—80+ workflows moved in 10 weeks—improved attribution, enabled localized onboarding (14 touchpoints in three weeks), and drove measurable gains: a 10% click uplift from mobile template optimizations, a 300% increase from a redesigned welcome email, and a 30% month-over-month increase in signups.
