“Email has always been at the heart of how we talk to our users. We started as a newsletter, sharing the top new products with people around the world. We've grown a lot since the early days, we send about a million emails everyday now. As a result, it's really important to get the newsletter out quickly and Mailjet has helped us improve both our sending speed and deliverability. The best part about working with Mailjet is that I don't have to think about it, it just works.”

“Sending newsletters is the simplest and most direct method for staying in contact with our users. We put these newsletters together using the design tools available in the Mailjet application, which are very easy to use. The design and organization of messages can be done in a few clicks. It is particularly important for us because we operate in around thirty countries today and for this reason we communicate in more than 15 languages, all while maintaining a coherent design and conforming to our graphics chart in each of our emails, as this is an essential point in our marketing strategy and in conqueriing new markets.”
