Still not sure why you should go for Mailazy ! Know straight from our customers

  • Our onboarding emails were our biggest customer experience bottleneck. Password resets getting lost in spam, activation links expiring – it was a mess. Mailazy changed the game and had a direct, positive impact on our activation rate and customer retention.

    RapidTask - Alex Ngu, Head of Product

    We were skeptical that just changing our email delivery would make a huge difference for our marketing campaigns. But the numbers speak for themselves. After switching to Mailazy, our open rates jumped almost 10%, and we're seeing a higher conversion rate on our promotional emails. Turns out, getting past spam filters and into the inbox is half the marketing battle!

    Insightsly - Emily Woo - Head of Marketing

  • Before Mailazy, we'd spend way too much time troubleshooting email deliverability issues for our clients. It was a frustrating distraction from our core development work. Mailazy provides reliable infrastructure that's easy to integrate with our clients' projects. Now we can confidently deliver apps knowing the critical email components will work seamlessly, enhancing both our services and our clients' overall experience.

    SwiftDev Studio – Sarah Woods, Project Lead

    We were looking for a way to differentiate our agency. Partnering with Mailazy allows us to offer a premium email deliverability solution as part of our service packages. It not only resolves a common pain point for clients but demonstrates our commitment to performance and reliability. Mailazy has helped us increase client satisfaction and even opened up new revenue streams.
