Case Study: SIGNiX achieves reliable delivery of 4M monthly e-signature notifications with Mailgun

When Transactional Email Preps 4 Million Contracts For E-Signature Every Month

SIGNiX, a digital signature provider that prepares roughly 4 million contracts for e-signature each month, relied on transactional email as its primary notification channel. As volume grew, managing deliverability and consistency in-house became unsustainable—missed or delayed emails directly blocked signings and frustrated clients.

By partnering with Mailgun, SIGNiX outsourced email delivery and gained reporting, suppression management, bounce notifications and real-time performance visibility, along with improved domain and IP reputation. The result: more reliable 24/7 delivery, happier clients, stronger customer support, and the ability to focus internal resources on other aspects of system performance and strategic differentiation.
