Add SendGrid Integration for Course Registration Emails

I need to send confirmation emails to participants who register for training courses. The built-in SendEmail integration only works for users within the app, but I need to email external participants. Please add SendGrid integration with the following capabilities: - Send confirmation emails to any email address (not just app users) - Send reminder emails before training sessions - Send admin notifications for new registrations My use case: - Staff members register for CPR and Mask Fit Testing courses, and they need immediate email confirmations with their training details.

Thank you, 

Warren
