It’s nice to spice up your transactional emails with a few images from time to time. Even if it’s just a logo, you’ll find it helps to add a touch of legitimacy to what you’re sending out. However, there’s no one way to do this. Do you link out to the image on a CDN? Do you embed it and reference it via a CID tag? Maybe as a linked image? Which one should you choose? In this post, we’ll look at the options available and address a few pros and cons of using them, as well as how you…READ MORE »
Our Event Webhook is a great way to get a realtime view of what’s going on with the emails you’re sending from your application. However, a sudden spike in the amount of events coming back to your app could cause problems – especially if your webhook endpoint is on the same production server as the rest of your app. It would probably be good to know just how many events your app can handle before you see some degradation in performance, or maybe you split off your event notifications collection script on a totally different server. A quick and easy way…READ MORE »
Each month we get lots of tweets to our main @SendGrid account from users, potential users, and people on the hunt for free schwag. Many of these tweets are answered directly by our team of Developer Evangelists but we thought that some of the answers to those questions might be of interest to more of you, so we’re going to try and highlight a few interesting ones each month and give those answers a more permanent home. Here’s a selection from the past few weeks and their answers: Question 1: Subusers @SendGrid question: can subusers have their own unsubscription and…READ MORE »
SendGrid’s webhooks for inbound parse (receiving email) and events are great for hacking with, but they can be difficult to test in a productive manner because you have to keep deploying your code to the live server in order to get our webhooks to hit it, right? Wrong. In this post I’m going to show you how to work with ngrok to make local development with webhooks easier than ever. Install ngrok on Your Development Machine It’s always nice when there’s a good set of installers for things like this, you can download ngrok for OSX, Linux and Windows. It’s…READ MORE »
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. It’s quick to turn around…READ MORE »
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. Jim wrapped up the call by saying that he should probably let me get on. After all, wasn’t the Olympic opening ceremony about to start? It was a great…READ MORE »
