How Crunch Increased Email Deliverability and Prevented Domain Spoofing with EasyDMARC
Security Bouelevard, Tuesday, March 17th, 2026
Crunch Fitness is a global fitness brand operating hundreds of gyms worldwide. Known for its 'No Judgments' philosophy, the company provides fitness facilities, personal training, and group classes designed to make exercise accessible and engaging for a diverse community of members. With millions of members and a large digital communication footprint, Crunch relies heavily on email to support marketing campaigns, member communications, billing notifications, and operational updates.
The Challenge: Severe Deliverability Issues and Limited Authentication Visibility
Before implementing EasyDMARC, Crunch struggled with major email deliverability issues across multiple sending platforms. The company sends millions of emails each month, but lacked clear visibility into how authentication policies were affecting delivery outcomes.
According to William Schellhaas, VP of Technology Infrastructure at Crunch, the situation became critical when the team discovered that most emails were not reaching recipients.'We had multiple sending sources that were sending millions of emails every month. When we checked our numbers, we were actually getting an 8% deliverability rate and 92% was going to quarantine. At that time we were unsure why.'
