Hi Experts,

I have created one Schedulable global batch class which automatically sends an emails to Task's accounts contacts. so i have schedule that class to daily run on 1:00 am. but it will give an Below exception.

Package Visibility: Constructor is not visible: [SendMassEmail].<Constructor>()

---------- code  --------

global class SendMassEmail implements Database.Batchable<SObject>, Database.Stateful, Schedulable {
    // variable deleractions
    
    global SendMassEmail(){
      
      // nothing define  
    }
    
    global database.querylocator start(Database.BatchableContext bc){
    
        //  Fatching Task records.
    }
    
    global void execute(Database.BatchableContext bc, List<sObject> sObjs){
        // Factching Task's Accounts and its related contact
        // sendEmail();
    }
    
    global Boolean sendEmail() {
        // Select Email template based on task subject and send email
    }
    
    global void finish(Database.BatchableContext bc){
        System.debug('-------------- SendMassEmail FINISH ----------- ');
    }
    
    global void execute(SchedulableContext sc) {
        // call batch job
        SendMassEmail sme = new SendMassEmail();
        Database.executeBatch(sme,1);
    }
}
