Track SendGrid API changes, deliverability updates, and SDK releases
Monitor SendGrid API changes before your email campaigns stop sending
APIDrift scrapes the official SendGrid release notes at docs.sendgrid.com daily, tracking Mail Send API changes, sender verification requirements, and dynamic template modifications. SendGrid enforces authentication requirements that can cause emails to bounce, deprecates legacy Newsletter API endpoints, and modifies Handlebars template behavior. Because email delivery is critical infrastructure for marketing campaigns and transactional flows, advance warning of these changes prevents delivery disruptions.

SendGrid API changes can break your email campaigns and transactional flows
Email delivery is critical infrastructure. SendGrid's Mail Send API changes, authentication requirement updates, and dynamic template modifications can disrupt both marketing campaigns and transactional emails. A single breaking change can affect millions of emails.
“SendGrid enforced sender verification and our automated emails started bouncing because our sending domain wasn't verified under the new requirements. We lost two days of order confirmation emails before we caught it.”
