Tracking Email Using Microsoft Azure and the SendGrid Event Webhook (Part 2)

Posted on (0 Comments)

Welcome back to the second part of my series about building a Windows Phone 8.1 app to track email powered by Microsoft Azure and SendGrid’s Event Webhook. If you haven’t read part one in this series, please do so before continuing. Recap In part one, we implemented the SendGrid Event Webhook listener using C# ASP.NET hosted on Microsoft Azure. In this post (part two), we will create a Windows Phone 8.1 app that displays email tracking data via the SendGrid Web API. In part three of this series, we will send push notifications from our SendGrid Event Webhook listener when

JSON Web Tokens (Again!) and Koa.js

Posted on (0 Comments)

A few weeks ago, I wrote about using JSON Web Tokens (JWT) as an alternative method of authentication using Go. The post itself contains a basic explanation about JWT and some links for content. In this post, I want to cover pretty much the same things using Koa, a new framework for Node.js. Koa is mostly a middleware framework which uses generators (only available under the Harmony flag) to control the flow of requests. The reason I mention that it’s a middleware framework is because it doesn’t come with most of the things you would expect a framework to provide, such

The SendGrid Ruby Gem and My Mama!

Posted on (0 Comments)

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! The library includes the smtpapi-ruby library created by our friend Wataru Sato of SendGrid Japan. As always, any sort of feedback is welcomed and encouraged. What better way to introduce a new library than with a hack!? My mother, like most moms I imagine, was very sad and hesitant to see her baby boy move out and start life on

Gophers can haz A/B Testing in Transactional Email

Posted on (0 Comments)

How much do you know about the awesome folks @SendWithUs? Here @SendGrid, we’re huge fans, and quite frankly friends, of theirs. They provide an amazing service: A/B testing for transactional email templates! If you haven’t heard from them and you are a SendGrid customer, today is your lucky day since we have a partnership that might interest you! But enough about that, lets get a bit technical! I noticed that SendWithUs didn’t have a Golang library. So I figured I could build them one and allow every Go developer out there to interact with their service without having to implement

Young Rewired State & Code on the Road

“It was a sea of Blue SendGrid T-Shirts. Everywhere I looked, I saw SendGrid! You guys rock!” My first answer when asked the question “What do Developer Evangelists do?” is always: We empower and nurture developers. In previous talks I’ve given and articles I’ve written, I’ve described how teaching, mentoring, empowering, and nurturing are the most important parts of my job, and there’s no age limit to which this help is confined. In the many hackathons I (and the rest of the Developer Evangelist team) travel to, I see developers of all ages and I’m never more impressed, and quite

Gist Me Please?

Posted on (0 Comments)

Do you find yourself writing technical blog posts in Markdown and exporting them to HTML? Do you end up writing GitHub Flavored Markdown and then exporting to blocks or something similar? I know I used to do that quite often. Thats the reason I created Propagandist. Propagandist is a simple tool which will parse out your Markdown and convert it into HTML. The cool part is that every Code Snippet that it finds gets replaced with a Gist for it. This produces a central Gist with all the snippets that users can jump into. Propagandist is built on top Gost

NSLog(@”Updated iOS Library”)

Posted on (0 Comments)

Most ESPs make sending email through their services super easy. On top of that, we at SendGrid have libraries for most languages/frameworks like, Node, C#, Java, etc. Last year Kunal Batra created the Objective-C library, and we had great feedback from a lot of people saying how easy it was to use. During the past couple weeks I spent some time working on the Objective-C library, and getting it more up-to-date with the others. Now, as in other languages, we have a library called “SMTPAPI,” which helps easily build the X-SMTPAPI headers for additional functionality while sending email. We also have the SendGrid
