If you haven’t been living under a rock, you probably know that SendGrid released Transactional Templates recently. I’ve been using them for a while, specifically for my API demos. It makes it super simple for me customize emails for a specific school or crowd on the fly without touching any code. With Transactional Templates I don’t ever touch my code. Here is how my code looks like: Now if I want to go to HackRU and give a demo, I don’t have to change anything in my code. I can go to the Templates interface and activate the template that

Posted on (0 Comments)

Recently, SendGrid celebrated five years since we formed the company. Five years and over 270 billion emails later, I want to share some of my thoughts on some key lessons I’ve learned along the way. Design For Failure One of the biggest mistakes we made in the initial creation of SendGrid was focusing on getting a feature working, and then moving on to the next piece.

In early 2009, I finished a prototype to help increase email deliverability. But solving email delivery wasn’t a one-person job. So, I approached Tim Jenkins, one of the smartest people I knew, to join the mission of increasing email deliverability for businesses. Tim joined to be responsible for all backend systems. But, backend systems would be unusable without web applications. So I called on the perfect person for this, Jose Lopez. Once Jose joined, the three of us were ready to begin our journey. Two years later, in 2011, I went from SendGrid’s CEO, to a role of learning. I

At the end of this three-part blog post, you will have created a Windows Phone app that can receive push notifications when certain email events happen (e.g. email opened or link clicked), in near real-time.
