Send automatic Email to user when an Apex job terminates its execution

Hi everyone,

We have an Apex job/batch which executes each week and deletes all Contact records whith a certain condition (let suppose, ActivationDate__c older than 24-months).

How should I edit this Apex job in order to send automatically an Email to a Salesforce user whenever it finishes to comunicate the result (such as: success or failure/exception)?

 

Thank you so much,

Skender

On a Batch, we can use the finish method "to send confirmation emails or execute post-processing operations". 

For example:  
global class BatchClass implements Database.Batchable<sObject>{

   global BatchClass(){ //Constructor
   }

   global Database.QueryLocator start(Database.BatchableContext BC){
        //Start method
   }

   global void execute(Database.BatchableContext BC, List<sObject> scope){
        //Execute method
    }

   global void finish(Database.BatchableContext BC){
        // Get the ID of the AsyncApexJob representing this batch job
        // from Database.BatchableContext.
        // Query the AsyncApexJob object to retrieve the current job's information.
        AsyncApexJob a = [SELECT Id, Status, NumberOfErrors, JobItemsProcessed, TotalJobItems, CreatedBy.Email FROM AsyncApexJob WHERE Id = :BC.getJobId()];
        
        // Send an email to the Apex job's submitter notifying of job completion.
        Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
        String[] toAddresses = new String[] {a.CreatedBy.Email};
        mail.setToAddresses(toAddresses);
        mail.setSubject('Apex Sharing Recalculation ' + a.Status);
        mail.setPlainTextBody
        ('The batch Apex job processed ' + a.TotalJobItems +
        ' batches with '+ a.NumberOfErrors + ' failures.');
        Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });
   }
}

Hi Skender,
Firstly, you need to abort the process to modify anything in the running class, then you can add the logic of sending mails in your finish method of the batch Apex.
