AZ-204 Practice Question: Connect to and consume Azure services and third-party services
You need to send email notifications from an Azure Function app when a new user registers in your application hosted on Azure App Service. Which Azure service should you use to send the emails?
⚠ Common exam trap
The trap here is that candidates might choose Azure Communication Services because it now supports email, but SendGrid is still the recommended and simplest option for transactional emails from Azure Functions due to its native output binding and lower cost for high volumes. Alternatively, candidates might overcomplicate the solution by choosing Logic Apps when a simple output binding suffices.

Correct answer & explanation
✓
SendGrid
SendGrid is a cloud-based email delivery service that integrates directly with Azure Functions via an output binding, making it the simplest and most cost-effective option for sending transactional emails like registration notifications. It handles SMTP relay, deliverability, and scaling without requiring a dedicated email server or complex configuration.
