Last month, I had the pleasure of representing SendGrid at Totango’s second annual Customer Success Summit in San Francisco. This event marked an important milestone for SendGrid because it acknowledged our past dedication to customer success and our future promise to deliver even more in 2014. Embracing the Customer Experience The days of selling software, hoping customers don’t call for support and praying that they renew are over. Companies must prove their value everyday—all the time.

Hack Video Games With SendGrid

Posted on (0 Comments)

The following is a guest post from Alex Reed, one of SendGrid’s European Ambassadors. I would be lying if I didn’t say that my favourite feature in the SendGrid API set is the Inbound Parse Webhook. Being able to receive email into a web application/service, as easily as SendGrid makes it, is an absolute joy! (It even allows the parsing of attachments, and email header-data!) My background is C#, making apps to hack video games, and some Ruby doing web services. Gaming is a huge part of my background, which actually got me into programming in the first place. So

Freelancing is supposed to be fun, right? You set your own hours. You choose the work you find interesting.

Posted on (0 Comments)

Recently, I had the chance to teach kids how to launch rockets using Arduinos. As you might guess, it was a blast. We wrote a countdown program using Node.js, hooked the program up to an Arduino, and wired up the Arduino. This sent an electrical signal to the rocket engine, igniting it. In this tutorial, I show you how to do the same. Prerequisites You will need the following materials: Arduino Mega 2560 Board. You could use a different Arduino board, but I recommend the Mega. NodeJS installed on your computer. It is relatively easy to install. You can go

Posted on (0 Comments)

Dear Gmail Team, Gmail will be 10 years old next month. Congrats! I love the innovations you’ve made over the past decade. Thanks to you, my email is more useful and accessible than it ever was. I’m delighted by the Gmail feedback loop, one of those behind the scenes innovations that regular users won’t notice.
