At MileIQ, email is an important part of our engagement strategy. On a monthly basis, we are sending about 10M emails, powered by Mailjet. The majority of emails are transactional and lifecycle as the user engages with the service. We were looking for a partner that could offer really solid customer support and service as we figured out how to design this service, and we needed an ESP that would scale with us over time. For me, the key reason to work with Mailjet is we know we have a partner that wants to scale with us as we grow our business and I think that’s really important.
