Twilio SendGrid supports Secure Sockets Layer (SSL) enabled click and open tracking. To enable SSL click and open tracking for an authenticated domain with branded links, additional configuration for the SSL keys is required.
In order for click and open tracking to work over SSL, Twilio SendGrid needs to present a valid SSL certificate that will be trusted by the email recipient's security mechanism. For authenticated domains, Twilio SendGrid is not able to request and/or manage certificates, as it is not the record owner for the domain.
There are two options for SSL certificate configuration:
- Use a Content Delivery Network (CDN) service, such as CloudFlare, Fastly, or KeyCDN to manage certificates and keys for your domain.
- Setup a custom SSL configuration.
Once you have followed the configuration guide for either of these services, please contact Twilio SendGrid Support to enable SSL click and open tracking for you. Once SSL click and open tracking is enabled, you can access the data via the UI (Stats or Activity Feed) or API (Email Activity or Stats).
