Email alert not firing from the batch class

Hello All

i need a small help, i am trying to design an apex batch class where when lead is not modified for more than 24Hrs, Then Automatically email should fire to  lead owner and lead owners email address, For lead owner emaill address, i have created a process builder where lead owners manager email is populated when lead is newly created, i tried this with workflow and Timebased workflow rule, but still not working properly

Below is my Batch apex class
global class Emailalertbatchclass implements Database.Batchable<sObject>, Schedulable, Database.Stateful {
    //Variable Section
    global FINAL String strQuery;
    global FINAL String leadid;
    global List<String> errorMessages = new List<String>();
    global Emailalertbatchclass() { 
        this.strQuery = getBatchQuery();
    //Returns the Query String to Batch constructor to fetch right records.
    private String getBatchQuery() {
        String strQuery = 'SELECT Id,Name,Status,Email,owner.email,owner.name,ownerid,No_Enquiry_Email_Sent__c,Manager_Email__c FROM Lead where No_Enquiry_Email_Sent__c=false AND Status=\'Enquiry\' And (CreatedDate = YESTERDAY OR LastModifiedDate = YESTERDAY) limit 1';
        return strQuery;
    //Batch Start method
    global Database.QueryLocator start(Database.BatchableContext BC) {
        return Database.getQueryLocator(strQuery);
    //Batch Execute method calls findCostForWoD method
    global void execute(Database.BatchableContext BC, List<sObject> scopeList) {
        System.debug(LoggingLevel.INFO, '== scopeList size ==' + scopeList.size());
        List<Lead> ld = (List<Lead>) scopeList;
        List<Lead> updatedld = new List<Lead>();
        if(!ld.isEmpty()) { 
            List<Messaging.SingleEmailMessage> mailList = new List<Messaging.SingleEmailMessage>();
            for (Lead prod : ld)
                // Step 1: Create a new Email
                Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
                // Step 2: Set list of people who should get the email
                String[] toAddresses = new String[] {prod.owner.Email,prod.Manager_Email__c,'chandra.s@proseraa.com'};
                // Step 3: Set who the email is sent from
                mail.setSenderDisplayName('No Activity on Leads for 24hrs');
                // (Optional) Set list of people who should be CC'ed
                List<String> ccTo = new List<String>();
                // Step 4. Set email contents - you can use variables!
                mail.setSubject('No Activity on Lead for 24hrs');
                String body = 'Dear ' + prod.owner.name + ', <br><br>';
                body += 'This is to notify you that there is no activity done on the respective <b> Lead Name: ';
                body +=prod.Name+'</b>  please find the link below..<br><br>';
                body += 'link to file: https://moengage--proseraa.lightning.force.com/lightning/r/Lead/'+prod.id+'/view'+'<br><br><br> Thanks,<br>Moengage Team</body></html>';
                // Step 5. Add your email to the master list
                prod.No_Enquiry_Email_Sent__c = true;
            if(!mailList.isEmpty()) {
                    update updatedld;
                catch (Exception ex) {
                    errorMessages.add('Unable to send email to Tech: '+ ex.getStackTraceString());
    //Batch Finish method for after execution of batch work
    global void finish(Database.BatchableContext BC) { 
    //Method which schedules the ProductDownloadBatch
    global void execute(SchedulableContext sc) {        
        Emailalertbatchclass snInstance = new Emailalertbatchclass();
        ID batchprocessid = Database.executeBatch(snInstance);

and Below is my schedular class
global class Scheduleerclassemailalert implements Schedulable
    global void execute(SchedulableContext SC) { 
         Emailalertbatchclass snInstance = new Emailalertbatchclass();
        ID batchprocessid = Database.executeBatch(snInstance); }
so how do i resolve this issue??

Hi Manjnath,

This can be achieved with the help of Time Dependent Workflow Action. We don't need to build a custom class for this.

Please see the Link metioned bellow:
