Custom agency website for Mailboosters

Online Helden developed a fully custom-built website for Mailboosters, a Klaviyo Gold Partner and leading email marketing agency based in Breda, Netherlands. With clients such as MB Nutrition and other large online stores, it was crucial that their new website reflect Mailboosters’ expertise and professionalism. The old website no longer met Mailboosters’ needs and no longer provided the desired look and feel. Therefore, we realized a minimalist and modern design befitting their status as a leading email marketing agency.

Project scope
Mailboosters asked us to design and build a new website, as the old one was now somewhat dated and no longer made the desired impression. The goal was to create a modern, minimalist and future-proof website that would highlight their status as a leading email marketing agency.
For this assignment, we chose a completely custom design, every detail was completely custom designed. The minimalist design combines shades of white and blue with plenty of space, clean lines and subtle animations and effects. This makes the website look not only professional, but also visually appealing. We also optimized all aspects of the site, from code to loading speed, and housed the site in our managed hosting environment for maximum performance and security.
The result is a modern and minimalist website that perfectly matches Mailboosters’ identity. With an average PageSpeed score of 98/100, the site offers not only an impressive user experience, but also lightning-fast performance on both desktop and mobile. The new website exudes professionalism and innovation and is designed to impress existing and potential clients. With the combination of high-quality hosting and thoughtful design, Mailboosters is all set to welcome their visitors in style.
