Automatic SSL Certificate Provisioning for Link Branding
SendGrid now offers automatic SSL certificate provisioning for branded links, eliminating the need for external certificate management. A new auto_ssl parameter in the Link Branding API enables this feature, with certificates provisioned and hosted by SendGrid alongside traditional link branding DNS records.
Twilio SendGrid has added automatic SSL certificate provisioning as a toggle within the standard link branding setup flow. When enabled, SendGrid provisions and hosts the SSL certificate needed to serve tracking and branded links over HTTPS, removing the need to purchase, install, and maintain a certificate through an external CDN or DNS provider.
Twilio SendGrid recommends activating this setting for all link branding domains. Gmail is rolling out warnings on non-HTTPS links by the end of October 2026, and tracking links without SSL will see reduced click-through as a result. Enabling automatic SSL requires adding two additional DNS records provided by SendGrid, alongside the CNAME records already used for link branding.
The Link Branding API now supports a new auto_ssl parameter when creating a branded link. Setting auto_ssl to true provisions the certificate automatically, returns the additional DNS records needed to complete setup, and reports certificate status through a new auto_ssl_available field once the certificate is issued and live. auto_ssl can only be set when a link is created and can't be changed afterward.
