We strive to provide helpful, interesting, and informative content about all things email on the SendGrid blog. In June, we touched on some great topics, including email security, email templates, and webhooks. In case you missed them, below is a wrap-up of the blog posts that we think you’ll find most helpful to your email campaign: SendGrid and the Future of Email Security Our Chief Security Officer, David Campbell, announced that SendGrid is now utilizing opportunistic TLS encryption to make sure that the mail customers send through SendGrid is secure. SendGrid’s Template Engine Tutorial We provided an online tutorial to guide customers through implementing and using our new email Template Engine. For customers that missed the live tutorial, this post provides a transcript of what was covered. Intro to Golang We covered even more reasons we go with Golang in a post that demonstrates exactly what’s good and great about the language. Robin Johnson provided some excellent examples of how quick and easy Golang is (and why he won’t stop talking about it). CAN-SPAM Compliance: Breaking it Down Making sure your email is CAN-SPAM compliant is very important for any organization. This post covers the basics of the legislation, as well as what you can do to make sure you’re ok. What’s a Webhook? You probably already know we love them after all our posts about the Event Webhook and Parse Webhook, but we wanted to dive a little deeper. Nick Quinlan provided a great rundown of what a webhook is and how it can be used. To get notified of new blog posts that can help you improve your email program, just subscribe to the SendGrid blog.
