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,recordtype.name FROM Lead where No_Enquiry_Email_Sent__c=false AND recordtype.name=\'Lead Registration\' AND Lead_Intent_Type__c=\'High Intent Lead\' AND Status=\'Enquiry\' And ((DaysSinceLastActivityDone__c>=0) OR (DayssinceEnquirystage__c >= 0))';
        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) {

            {

                    if(prod.Manager_Email__c!=null && prod.Manager_Email__c==''){
                        toAddresses.add(prod.Manager_Email__c);
