THE CHALLENGE

Collect’s expansion revealed major limitations in their email infrastructure. “As we grew, scaling our email infrastructure became a major bottleneck,” said Founder Alex Delivet. The team faced technical hurdles that restricted email volume, experienced deliverability issues as sending scaled up, and spent excessive time on domain setup and maintenance. These challenges made it clear that a stronger, more scalable infrastructure was essential. It needed to handle high-volume outreach while allowing technical teams to focus on strategic work instead of ongoing maintenance.

THE SOLUTIONS DEPLOYED

To overcome their scaling challenges, Collect turned to Mailpool’s automated email infrastructure. Mailpool offered scalable sending capacity, automated domain setup and management, and built-in deliverability optimization, all designed to support high-volume outreach with minimal manual effort. “What impressed us was the simplicity,” notes Alex Delivet, Founder of Collect. “With Mailpool, we could scale from 5,000 to 100,000 monthly emails while improving our deliverability.”

RESULTS AND IMPACT

The results were immediate and significant. Collect’s monthly email volume increased tenfold, while deliverability improved from 62% to 95%. Domain setup time was reduced dramatically, from four hours to just five minutes per domain. “Mailpool transformed our ability to scale,” says Alex. With reliable high-volume sending, automated infrastructure management, and consistent deliverability, the technical team was finally free to focus on core product development instead of backend maintenance.

KEY FEATURES LEVERAGED

‍Automated Set-up

Collect experienced a major shift in efficiency with Mailpool’s automated setup features. This streamlined process minimized errors, ensured consistency across regions, and allowed the team to scale outreach efforts with ease. “The ability to deploy new sending infrastructure in minutes instead of hours changed everything,” shared Alex, highlighting how impactful automation was in accelerating their operations and supporting their expansion.

‍Deliverability optimization

Collect saw significant improvements in email performance thanks to Mailpool’s deliverability optimization features. By having an automated email authentication standard set up and a complete deliverability audit, Mailpool ensured that emails consistently reached inboxes. This allowed Collect to expand their outreach without sacrificing reliability. According to Alex, “Even as we scaled to 100,000 monthly emails, our deliverability stayed above 95%,” emphasizing how Mailpool helped maintain strong performance even at high volumes.

Domain management

Collect experienced a major transformation in managing their email infrastructure with Mailpool’s domain management features. What was once a complex, error-prone process involving manual DNS setup and constant technical oversight became fast, reliable, and user-friendly.  As Alex shared, “Managing multiple domains went from a technical nightmare to a simple dashboard operation,” capturing the ease and efficiency Mailpool brought to their daily operations.

LESSON AND BEST PRACTICES

Preparing email infrastructure for scale early is critical for any SaaS company looking to grow efficiently. Automating technical setup and ongoing maintenance not only streamlines operations but also minimizes the risk of errors and delays. As email volume increases, actively monitoring deliverability ensures consistent performance and protects the sender's reputation. Building on a reliable sending infrastructure provides the stability needed to support long-term growth. “For any SaaS planning to scale their email operations, robust infrastructure isn't optional; it's essential,” advises Alex. “It's about building for growth from day one.”

"As we continue expanding our platform globally, having Mailpool manage our email infrastructure gives us confidence in our ability to scale further. We can focus on growth, knowing our email foundation is solid."
