Hi,
Try with below code, 
// Create two accounts, one of which is missing a required field
Account[] accts = new List<Account>{
    new Account(Name='Account1'),
    new Account()};
Database.SaveResult[] srList = Database.insert(accts, false);

// Iterate through each returned result
for (Database.SaveResult sr : srList) {
    if (sr.isSuccess()) {
        // Operation was successful, so get the ID of the record that was processed
        System.debug('Successfully inserted account. Account ID: ' + sr.getId());
    }
    else {
       // send mail 
        }
    }
}

for more clarification on this go through below link.

Example 1:- 
global void execute(Database.batchablecontext bc) {

    // Check batch status - IF COMPLETED then 
    AsyncApexJob a = [Select Id, Status, NumberOfErrors, JobItemsProcessed,
        TotalJobItems, CreatedBy.Email, ExtendedStatus
        from AsyncApexJob where Status == 'Failed'];        

    if(a.Status == 'Failed') {


        // 1. Send Email (CSV created in execute method)


        Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
        // Send the email to the job submitter
        String[] toAddresses = new String[] {a.CreatedBy.Email};
        mail.setToAddresses(toAddresses);
        mail.setSenderDisplayName('Batch Processing');
        mail.setSubject('x70RecordExtract  Status: ' + a.Status);
            mail.setPlainTextBody('The batch Apex job processed ' + a.TotalJobItems +
            ' batches with '+ a.NumberOfErrors + ' failures. ExtendedStatus: ' + a.ExtendedStatus);

        // Add your attachment to the email.

        Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });


        // 2. database.executebatch(new chain_batch(),200);

    }
}


Exmaple 2:-  
global class TestBatch implements Database.Batchable<sObject>, Database.Stateful {

    global List<Log__c> logs;

    global TestBatch() {
        logs = new List<Log__c>();
    }

    global Database.QueryLocator start(Database.BatchableContext BC) {
        query = 'Your query...';
        return Database.getQueryLocator(query);
    }

    global void execute(Database.BatchableContext BC, List<sObject> scope) {
        for (sobject s : scope) {
            try{
                Your logic goes here...
            } catch (Exception e) {
                logs.add(new Log__c(
                        Name__c = '...',
                        Stacktrace__c = e.getStackTraceString()
                    ));
                throw e;
            }
        }
        update scope;
    }

    global void finish(Database.BatchableContext BC) {
        insert logs;
    }
}
