Scaling MySQL at SendGrid

Posted on (0 Comments)

SendGrid is the epitome of catching a tiger by the tail. Our systems were not originally designed to handle the massive scale we deal with today. Adding new features at this scale also presents challenges budding companies don’t yet need to design for. With our growth and overall traffic, we have had to come up with solutions to handle challenges related to simply scaling our datastores. At SendGrid, a large portion of our data is housed in 10 distinct MySQL datastores with a total of 87 physical machines and 255 MySQL instances. We also have a varying combination of challenges

Posted on (0 Comments)

Okay, I totally get it. I’m a recent graduate from business school and my emphasis was in marketing. I know a big list of email addresses is great. And an even bigger list? Even better! But what’s the deciding factor between epic email program success (where clicks and opens rain down like confetti) and unengaged, sad recipients (who throw spam complaints at you like it’s their job)?

Do you remember when you started going to hackathons or just basically started to do cool stuff? I remember it very clearly. In those days I gained a very dear friend, Daniel Santiago. Every so often I bug him with Java/Android stuff since he is a baller Android Developer. My questions were usually about adding support to the Java library.

I don’t know about you, but I value this gesture more than almost any

According to The Radicati Group’s Email Statistics Report for 2013-2017, over 100 billion business emails are sent and received every day.

Posted on (0 Comments)

Here’s the deal: email continues to outperform social media when it comes to customer engagement, and it doesn’t look like that’s going to stop anytime soon. According to the Radicati Group, there are more than 100 billion wanted emails sent everyday… and that number is expected to rise: According to Forrester Research, user interactions with companies on social websites peaks with Instagram at 4.21%, followed by Facebook at .07%, and Twitter at .03%. Those numbers only represent interactions, and they don’t necessarily mean that viewers took the next step to visit their website. Email, on the other hand, gets much

Last year I got to ride on the StartupBus from New York to Austin, Texas. My team and I created a StartUp in 3 days, got the ability to demo in front of some amazing judges and got great feedback/friends along the way.
