A sample of the things I love are, Ruby, webhooks, and my mama! In this post, I’m putting all of them together! Let’s start with how excited SendGrid is to announce the release of the official SendGrid Ruby Gem, sendgrid-ruby!

Earlier this month, Isaac, Jose, and Tim wrote letters about what their first 5 years of scaling SendGrid has been like. A common theme for all of them was our customers and our people. At the center of both of these is our Customer Success team. They’ve scaled tremendously over the past 5 years to ensure that our customers are able to do so as well. I wanted to learn a little more about their team and what this support looks like, so I sat down with Amy Mustoe, SendGrid’s Director of Customer Success, to get some more insight. Q:
