Does a user need to be registered in Appwrite to receive an email?

If I want to send an email (for example, to xyz@gmail.com) from an Appwrite Cloud Function, does that email address need to be registered as a user in Appwrite? Or can I send an email to any address, even if the recipient is not registered in the Appwrite?

I go through with this doc https://appwrite.io/docs/products/messaging/messages

I am using Appwrite Free plan

Yes, it needs to be registered, as the goal of this feature is to notify your own users

@Guille Thank for your response. Don't you think it should allow us to send email even if user is not register?

Can you give an example of your use case?

@Guille

What I want: I will add a storage event listener in a Cloud Function to monitor new file uploads.

The function will validate created file based on my defined criteria, and if a file fails validation, it will send an email notification to our support developer without requiring the this user to be registered.

As I understand, you need to send an email to your support developer, so they should be registered, or I'm missing something?

You want the developer know what is the user with problem?
