A company like Pinterest has millions of transactional emails to send to people. The scalability challenges of sending high volumes of email mean that it makes more sense for most companies to use an email as a service product rather than building their own.
Chris McFadden is the VP of engineering and cloud operations at SparkPost and he joins the show to explain the architecture of SparkPost’s email as a service product. SparkPost started as an on-premise email technology for large enterprises, and evolved into a SaaS product. In 2014, the company migrated to the cloud, which has changed its infrastructure as well as its operational model.
