Case Study: Quantum Response Network achieves 13x faster, more reliable global job-alert delivery with Mailgun

Sending Millions Of Job Alerts 24/7 With The Mailgun Email API

Quantum Response Network runs multiple global job sites and sends transactional and promotional job-alert emails to over 1.2 million active users across EMEA, APAC, and North America. Their challenge was reliably sending high volumes around the clock (starting at 3 a.m. local time) while maintaining deliverability and speed—tasks their previous provider handled slowly (taking up to 29 hours).

By integrating the Mailgun API, Quantum Response Network cut send time to under two hours (about 13× faster), improved deliverability and consistency, and scaled capacity to meet demand. The result: a 95% increase in monthly email sessions and a dependable partnership with Mailgun’s knowledgeable account team.
