Hi Prince, 

you can follow below code: 
global class accountInsert implements Database.Batchable, Schedulable{
    List<sObject> batchList;
	
	 global accountInsert(List<sObject> objList) {
      // modify list if necessary (e.g., trap null)
      if (objList == null) objList = new List<sObject>();      
      this.batchList = objList;
   }
	
	

    
    global void execute(Database.BatchableContext batchableContext, List<sObjects> objList){
        try{
            insert objList;
			emailOwners(objList);
        }catch(Exception e){
            System.debug('Exception :: ' + e.getMessage());
        }
        
    }
    
    global void finish(Database.BatchableContext batchableContext) { 
        
    }
    
   
    private void emailOwners(List<Account> accList){
        
        List mailList = new List();
        EmailTemplate templateId = [Select Id from EmailTemplate where DeveloperName  = 'Template Name'];
        for(Account acc : accList){
            Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
            mail.setTargetObjectId(acc.id);
            mail.setTreatTargetObjectAsRecipient(false);
            mail.setToAddresses(new List{acc.Owner.Email});
            mail.setTemplateID(templateId.Id);
            mail.setSaveAsActivity(false);
            mailList.add(mail);
        }
        if(mailList != null){
            Messaging.sendEmail(mailList);
        } 
    }
}

Hi Mukesh,

You can take reference from this below code:- 
global class InactiveApplication implements Database.Batchable<sObject>
{
    global Database.QueryLocator start(Database.BatchableContext BC)
    {
        String query = 'Select Id, Name, Owner.Email from Trade_Ally_Account__c where Stage__c = 'Prospecting' and LastModifiedDate = LAST_N_DAYS:31';
        return Database.getQueryLocator(query);
    }
 
    global void execute(Database.BatchableContext BC, List<Trade_Ally_Account__c> scope)
    {       
        EmailTemplate emailTemplate = [select Id, Body from EmailTemplate where DeveloperName = 'Update_Service_Request'];
        
        for(Trade_Ally_Account__c ta : (List<Trade_Ally_Account__c>)scope) {
            Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();
            email.setToAddresses(new String[] {ta.Owner.Email});
            email.setSaveAsActivity(false);
            email.setTargetObjectId(ta.OwnerId);
            email.setTemplateId(emailTemplate.Id);
            email.setWhatId(ta.Id);
            Messaging.sendEmail(new Messaging.SingleEmailMessage[] {email});
        }
    }  
    global void finish(Database.BatchableContext BC)
    {
    }
}

Hi suraj/mukesh

below is my code

Global class BatchEmail implements Database.Batchable<SObject>
{
    Global Database.QueryLocator Start(Database.BatchableContext bContext)
    {
        string accountsQuery = 'Select id, name, annualrevenue, fax, customerpriority__C, active__C from Account';
        return Database.getQueryLocator(accountsQuery);
    }
    
    Global void Execute(Database.BatchableContext bContext, List<SObject> recordsToProcess)
    {
        if(! recordsToProcess.isEmpty())
        {
            List<Account> accountsToUpdate = new List<Account>();
            
            for(SObject obj : recordsToProcess)
            {
                   
                   Account acc = (Account) obj;
                    acc.AnnualRevenue = 6000000;
                    acc.Fax = '99998888';
                    acc.CustomerPriority__c = 'High';
                    acc.Active__c = 'Yes';
                
              accountsToUpdate.Add(acc);
            }
            
           if(! accountsToUpdate.isEmpty())
            {
                Update accountsToUpdate;
            }
        }
    }
    
    Global void Finish(Database.BatchableContext bContext)
    {   
       EmailTemplate templateId = [Select Id from EmailTemplate where DeveloperName  = 'Testing'];
        List<account> lstAccount = new list<account>();
        for(Account acc : lstAccount)
        {
            Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
            mail.setTargetObjectId(acc.id);
            mail.setTreatTargetObjectAsRecipient(false);
          //  mail.setToAddresses(new String[] {ta.Owner.mail});
            mail.setTemplateID(templateId.Id);
            mail.setSaveAsActivity(false);
            lstAccount.add(acc);
           insert  lstAccount;       
            
             Messaging.sendEmail(new Messaging.SingleEmailMessage[] {mail});
        }
    }
}

Hi Prince,

Do you want to update account or insert account.? because  in FINISH method lstAccount list is empty that's why loop will not execute.

Please give me your requirment what exactly you want do

Regards
Mukesh

Hi mukesh 
Thanks for your response

i am getting these errors when trying to use your above code


Variable does not exist: batchList  (this.batchList = newAccList;)
Method does not exist or incorrect signature: void getQueryLocator(String) from the type DataBase (return Database.getQueryLocator(accountsQuery);)
Invalid loop variable type expected SObject was Account ( for(Account acc : accountsToInsert)
Variable does not exist: mail1 (Messaging.sendEmail(new Messaging.SingleEmailMessage[] {mail1});)
Expecting '}' but was: 'for' (for(Account acc : accountsToUpdate))

errors and corresponding code
