Send mail to the System Administrator

Question

I have tried this to send mail to the logged in user

String[] toAddresses = new String[] {UserInfo.getUserEmail()};
mail.setToAddresses(toAddresses);

This works fine for the users who have logged in, but I would like to send mail only to System Administrator.

Thanks in advance.

Answer 1

Basic idea would be to query user that you need (f.e. with system admin profile etc), and use email on that field. For example:

Profile sys_adm_profile = [SELECT Id FROM Profile WHERE Name = 'System Administrator'];
List<User> sys_adm = [SELECT id, Email FROM User WHERE ProfileId = :sys_adm_profile];
String[] toAddresses = new String[] {sys_adm.Email};
mail.setToAddresses(toAddresses);

There is better approach -- as well as email is being send to user, then mailsetTargetObjectId(userId) should be used to avoid limits of email that can be send for different email addresses. https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_classes_email_outbound_single.htm https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_gov_limits.htm#email_limits_section

Also those method of getting system admin profile is not perfect -- it would fail in orgs with non english language.

You can do it with just one query:

SELECT Email FROM User WHERE Profile.Name = 'System Administrator'

//if person select other gender then send email to system adiminstrator public class personClassHandler {

public static void sendEmailongenderselection(List<Person__c>newList,List<Person__c>oldList){
    
    List<Messaging.SingleEmailMessage>mails = new List<Messaging.SingleEmailMessage>();
  
    
    if(trigger.isAfter &&(trigger.isInsert||trigger.isUpdate)){
        for(Person__c p:newList){
            if(p.Gender__c=='Others'){
                Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
                
                List<String>toAddresses = new List<String>{};   
            
   List<User>u = [SELECT Email FROM User WHERE Profile.Name = 'System Administrator'];
                for(user ui:u){
                  toAddresses.add(ui.Email);
                }
                
          
          mail.setToAddresses(toAddresses);
                String body = 'Some one has selected others gender';
                mail.setHtmlBody(body);
                mails.add(mail);
                System.debug('mails'+mails);
            }
            messaging.sendEmail(mails);
            
        }
    }
    
}
