Best Practices

Do you send email to Canadian recipients? If so, new legislation called the Canadian Anti-Spam Law (CASL) affects you.

Check Spam Using the Parse Webhook


One of my favorite parts of SendGrid is our Parse Webhook. It’s a great tool that enables your applications to receive incoming email. One of the lesser known features of the API is the spam_report and spam_score parameters.

This is useful to discard emails that are spam and avoid your application from having to process junk mail. Try It Out To get an idea of how this works. I made a quick application using the Go language called Read More ›
