2010
In San Antonio, Texas, growing from a Y Combinator company into a global leader.

Mailgun delivers email for growing businesses, built around transactional and marketing messages. Its API lets small companies and enterprises send, receive and track them.
Founded in 2010 and headquartered in San Antonio, it went from a Y Combinator company to a leader in its market worldwide, and in 2019 acquired the Paris-based competitor Mailjet — together serving 290,000 clients in over 150 countries.
In March 2019 the company reached a turning point and began redesigning the website together with its flagship web application, needing a product design and development team capable of the highest quality in a competitive market.
The task was not a refresh: the application itself had to be reinvented.
The project had to produce a style guide covering everything, and a library of interface elements — not just screens.
The services had to expand beyond developers to marketers, who can now use the product directly.

What we did
Netguru helped design and build the web application and open the platform to marketers alongside the developers it was built for.
The flagship application was rethought rather than restyled, which is what the market position required.
A thorough style guide came out of the project alongside a library of interface elements, both lasting assets.
Expanding the services to marketers widened who the platform is for without losing the developer audience.
The newly appointed Head of Product had already run a successful project with us at his previous company, and did not hesitate to work together again.
Client testimonial
Time zone differences between the US and Poland might seem an inconvenience, but it was actually an advantage for us. We were able to give requirements by the end of the day in the US, and Netguru would work through those requirements while we were sleeping.
