We’re happy to announce a brand new case study of a great SendGrid customer: DonorsChoose.org. DonorsChoose.org pioneered crowd funding for charity in April 2000.

Learning from a Couple Email Unsubscribe “No-Nos”

Posted on (0 Comments)

Unsubscribing is the process by which recipients voluntarily remove themselves from your email list. When a person decides they no longer want to hear from you, it’s your job as a sender to make sure the removal process is swift and easy. The CAN-SPAM ACT of 2003 specifically addresses the issue of unsubscribe. Because of the nature of transactional email, especially relative to that of marketing email, it is exempt to the guidelines of the CAN-SPAM Act.  Specifically when sending transactional emails, a company is not required to include a physical postal address or include an email unsubscribe link.

Do you find yourself writing technical blog posts in Markdown and exporting them to HTML? Do you end up writing GitHub Flavored Markdown and then exporting to blocks or something similar? I know I used to do that quite often. Thats the reason I created Propagandist. Propagandist is a simple tool which will parse out your Markdown and convert it into HTML. The cool part is that every Code Snippet that it finds gets replaced with a Gist for it. This produces a central Gist with all the snippets that users can jump into. Propagandist is built on top Gost

NSLog(@”Updated iOS Library”)

Posted on (0 Comments)

Most ESPs make sending email through their services super easy. On top of that, we at SendGrid have libraries for most languages/frameworks like, Node, C#, Java, etc. Last year Kunal Batra created the Objective-C library, and we had great feedback from a lot of people saying how easy it was to use. During the past couple weeks I spent some time working on the Objective-C library, and getting it more up-to-date with the others. Now, as in other languages, we have a library called “SMTPAPI,” which helps easily build the X-SMTPAPI headers for additional functionality while sending email. We also have the SendGrid

Posted on (0 Comments)

As we mentioned in the previous Q&A follow-up post, we received so many great questions during our webcast, Tips and Tricks to Stay Out of the Spam Folder, we had to wrap them up in two different blog posts. Even senders with the best intentions (sending wanted email) can end up in the spam folder. To finish off the Q&A, our presenter, and Senior Technical Account Manager, Melanie Rowe, took the second half of questions we received to answer: Q:  Do you need all three authenticating practices (DKIM, SPF, and DMARC)?  A:  The two main methods of authentication that you should implement are

Do you have an email list and want it segmented by geographic location? This blog post has got you covered! To accomplish this task, we take advantage of SendGrid’s Event Webhook.
