Switching from our own SMTP was only a matter of changing a few lines of code…The icing on the cake is that some deliverability best practices are built in and others are easy for us to automate on our own, making sender reputation management a breeze for us. For example, if someone marks one of our emails as spam, their address is automatically removed from our mailing lists.
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.
Ultimately, it matters that our emails get delivered to the recipient quickly and efficiently. We’ve got confidence in the performance, deliverability and reliability of the platform. We have plenty of other things to focus on when growing our business – so it’s nice to be able to rely on a partner like Mailjet for our email delivery.
