The EmailNotificationProvider can send e-mail notifications with IEmailService, which in turn will use the currently configured way of sending e-mails. This can be any of the built-in features (SMTP, local folder, Azure Communication Services), with configuration provided from the admin or from appsettings/the environment, or you can implement your own.

Can you please explain what's the exact scenario this doesn't cover? Why do you want to attempt to send e-mails via multiple alternative services? What is the problem you're trying to solve?

i want to send the email by gmail first which is free, if it failed , Azure Communication Services, if failed , other paid service, reasonable?

It's certainly a unique ask. However, it's something you can implement with some coding. Take a look at how this pipeline works by starting from here:

OrchardCore/src/OrchardCore/OrchardCore.Email.Core/Services/DefaultEmailService.cs

Line 27 in f59c1be

public async Task<EmailResult> SendAsync(MailMessage message, string name = null)

And here you can see that it's possible to loop through the registered providers:

OrchardCore/src/OrchardCore/OrchardCore.Email.Core/Services/DefaultEmailProviderResolver.cs

Line 31 in f59c1be

if (_providerOptions.Providers.TryGetValue(name, out var providerType))

Based on this, you can implement a new IEmailService, and within it, resolve multiple IEmailProviders to achieve what you're looking for.

That being said, I'd rather recommend you use a reliable e-mail service.

thanks for the suggestion. another similar question about SMS, HOW can we deal with that?

[Piedone]

It's the same pattern. Check out SmsService and DefaultSmsProviderResolver.
