public Messaging.SendEmailResult[] sendEmail(Messaging.Email[] emails, Boolean allOrNothing)

Type: Messaging.SendEmailResult[]
public Messaging.SendEmailResult[] sendEmailMessage(List<ID> emailMessageIds, Boolean allOrNothing)

This example shows how to send a draft email message. It creates a case and a new email message associated with the case. Next, the example sends a draft email message and checks the results. Before running this example, make sure to replace the email address with a valid address.
Case c = new Case(); insert c; EmailMessage e = new EmailMessage(); e.parentid = c.id; // Set to draft status. // This status is required // for sendEmailMessage(). e.Status = '5'; e.TextBody = 'Sample email message.'; e.Subject = 'Apex sample'; e.ToAddress = 'customer@email.com'; insert e; List<Messaging.SendEmailResult> results = Messaging.sendEmailMessage(new ID[] { e.id }); System.assertEquals(1, results.size()); System.assertEquals(true, results[0].success);
