Posted on (1 Comment)

Due to a recent printing fail, I’ve found myself without any business cards and I’m about to head out to How To Web in Bucharest for 3 days where I’m certain I’ll meet a few folks who ask for my details. Luckily, I work for a company that makes sending and receiving emails from an application easy, so I whipped up this quick app using SendGrid and Heroku to give me a quick autoresponder on my vanity email address that will send a digital version of my business card out to whomever emails that address.

Friday 27th July 2012 was the day I concluded the interview process for the role of Developer Evangelist at SendGrid. After talking with all of the team and the VP of Marketing, my final ‘chat’ was a late afternoon call with CEO Jim Franklin. An interview that will stay with me because we hardly talked about work stuff, mostly the kind of British food Jim liked and, somehow, something about trousers.

It’s been nearly a year since I made the move from developer to developer evangelist. As I see it, I get paid to do what I’d been doing anyway: hacking on projects and helping developers across Europe do the same. There are now more of my brethren on this continent, as I shared in The Rise and Rise of Developer Evangelism in Europe on The Next Web. Let’s look at why we’re seeing growth in Europe and what it takes to hire an evangelist or be hired as one. Why Evangelism is Growing in Europe Most current evangelists in Europe

Our inbound parse webhook makes it easy to start receiving emails into your application. Once you dig in you can start creating some really awesome internal tools to deal with what’s being sent to you. One of the types of emails you might be receiving is from your customers, and if you have a lot of customers this is probably going to amount to a huge pile of emails that may or may not get addressed in a timely manner, especially if you have no way of knowing which emails you should be prioritising. But what if you did know?
