Currently, Azure Power Platform does not provide SSL certificates as an add-on for Power Pages. However, you can bring your own SSL certificate and configure it for your Power Pages hosted on the platform.
To use your own SSL certificate, you would typically obtain it from a trusted certificate authority (CA) such as GoDaddy, as you mentioned. Once you have the SSL certificate, you can upload it to Azure Key Vault or any other secure storage service for safekeeping.
Next, you would need to configure your Power Pages to use the uploaded SSL certificate. This can be done by binding the SSL certificate to the appropriate custom domain associated with your Power Pages. The specific steps for configuring SSL certificates may vary depending on the hosting environment and services you are using.
Regarding certificate renewal, you would typically need to manage the renewal process yourself for certificates obtained from third-party CAs. This involves renewing the certificate before it expires and updating the certificate bindings on your Power Pages.
It's worth mentioning that the Let's Encrypt certificate you referred to is a free and automated certificate authority that provides SSL certificates. However, at present, Let's Encrypt is not directly integrated with Azure Power Platform or Power Pages.
If you require more advanced automation and management features for SSL certificates, you may consider using Azure Automation or Azure Functions in combination with Azure Key Vault to automate the certificate renewal process and perform any necessary configuration updates.
As for supporting email and automation needs with the SSL certificate, the certificate itself is primarily used for securing the communication between the client and your Power Pages. Any additional email or automation requirements would typically be handled separately, depending on your specific use case.
