Mail Sending to multiple users in Dynamics CRM + Plugin

Question

I'm writing plugin C#, to send an email to the users who are under SystemCustomizer role notifying that Contact is creating or Updating.

How to send an email to multiple users (Bulkmailing/ forEach loop for creating mail request to every user)?

Answer 1

Use a query to find each system user entity with the system customiser role.

Then for each user send an email. 1; create the email, 2; send the email.

// Create an e-mail message.
Email email = new Email
{
    To = new ActivityParty[] { toParty },
    From = new ActivityParty[] { fromParty },
    Subject = "SDK Sample e-mail",
    Description = "SDK Sample for SendEmail Message.",
    DirectionCode = true
};
_emailId = _serviceProxy.Create(email);

// Use the SendEmail message to send an e-mail message.
SendEmailRequest sendEmailreq = new SendEmailRequest
{
    EmailId = _emailId,
    TrackingToken = "",
    IssueSend = true
};

SendEmailResponse sendEmailresp = (SendEmailResponse)_serviceProxy.Execute(sendEmailreq);
