Tim is a co-founder at SendGrid.
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. While this was all well and good at low scale, once you have millions of messages going through the system every minute, the “one in a million” error cases start happening very regularly.

Recently, SendGrid decided to move to using Go as its primary development language.

For options on how to integrate with SendGrid go here. To start, the absolute best method to send email through SendGrid is to set up a local mail server that queues all email from your application, and then relays the messages through SendGrid as a smart host. This will have the least latency from your application’s perspective, and has the added benefit of handing your email off to…READ MORE »
