Our tech posts are written by our developer evangelists as a way to inform readers about some of the great things they are doing. Oftentimes, this means hacks they’re working on using SendGrid, events they’re attending, or how they’ve used SendGrid with another great piece of tech. Over the last couple months, we’ve tracked our most popular technical posts, and we’ve compiled them here. Check out what people have been reading and learning about: 1. The SendGrid Ruby Gem and My Mama! by Eddie Zaneski – This introduction to the new SendGrid Ruby library also features a hack that Eddie created to automatically text his mom any time he checks into a new city or state on Foursquare. 2. & 3.
