You need to create an apex scheduler class and send emails

Hi Veerendar,
You can try something like this 
List<User> listUser = [Select Id,LastLoginDate,Email FROM User ];
        List<String> userEmail = new List<String>();
        for(User u : listUser) {
            if(u.LastLoginDate.addDays(90) < System.today() ) {
                userEmail.add(u.Email);
            }
        }
        
        Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();
        
        email.setToAddresses(userEmail);         
        email.setSubject('Test Mail');
        email.setHtmlBody('Hello, <br/><br/>This is the test mail that you generated.');
        try{
            Messaging.sendEmail(new Messaging.SingleEmailMessage[] { email });
        }catch(exception e){
            apexpages.addmessage(new apexpages.message(apexpages.severity.error,e.getMessage()));
        }
Hope this helps!

Hi Raj,

I need a test class for the below apex class

global class EmailToUser implements Database.Batchable<sObject> 
{
List<String> UserEmailList = new List<String>();
    global Database.QueryLocator Start(Database.BatchableContext BC)
    {String query ='';
     User[] selectedUsers = [SELECT Id, email FROM User WHERE IsActive = TRUE AND Id NOT IN (Select UserId from LoginHistory WHERE LoginTime = LAST_N_DAYS:1)];
     //User[] selectedUsers = [SELECT Id, email FROM User WHERE IsActive = TRUE AND Id NOT IN (SELECT UserId FROM LoginHistory WHERE LoginTime = LAST_N_DAYS:30)];
        system.debug('users' +selectedUsers);
            
            return Database.getQuerylocator(query);
        
    }
    global void execute(Database.BatchableContext BC, List<User> scope)
    {
        for(User userobj:scope){
            userEmailList.add(userobj.email);
        }
    }
    
    global void finish(Database.BatchableContext BC)
    {
        List<Messaging.SingleEmailMessage> emails = new List<Messaging.SingleEmailMessage>();
        Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
        mail.setToAddresses(userEmailList);
        Mail.setSubject('Updating Subject');
        mail.setSaveASActivity(False);
        mail.setPlainTextBody('Sample Body');
        Messaging.sendEmail(new messaging.singleEmailMessage[] {Mail});
    }
}

Use this code . you can not insert the data in Login History object. In that case you can try SeeAllData=True in your test class.


try this code
  
@isTest(seealldata=true)
public class EmailToUseTest {
    public static testMethod void Test1(){
        Test.startTest() ;
        Database.executeBatch(new EmailToUser());
        Test.stopTest() ; 
    }
    
}
