Trigger to fire on Before Delete

Hi All,

I am having below trigger which calls a method "sendNotification" when the account name is changed. I want this trigger to call the method when the account is deleted ie)on before delete operation. Please help me on how this can be done.
trigger Contactcallout2 on Account(after update) {
List<Contact> ListContact = new List<Contact>();
Set<ID> acctIds = new set<ID>();
    for(Account acct : trigger.new) {
        if(Trigger.oldMap.get(acct.id).Name != acct.Name){
             acctIds.add(acct.Id);      
    }
    }
    if(acctIds.size() > 0){
        for(Contact con : [SELECT id,Email,FirstName,LastName,phone,Title__c,Account.Name,status__c, AccountId FROM Contact WHERE AccountId IN : acctIds AND RecordTypeid = '012D6765454BaFA']){
          WebServiceCallout.sendNotification(con.Id,con.Email,con.FirstName,con.LastName,con.phone,con.Title__c,con.Account.Name,con.status__c);
        }
    }
   }
Many Thanks in advance

Use Before delete and trigger.old.
 
trigger Contactcallout2 on Account(Before Delete) {
List<Contact> ListContact = new List<Contact>();
Set<ID> acctIds = new set<ID>();

if(Trigger.IsBefore && Trigger.IsDelete){
	
for(Account acct : trigger.old) {
        
             acctIds.add(acct.Id);      
    
    }
    if(acctIds.size() > 0){
        for(Contact con : [SELECT id,Email,FirstName,LastName,phone,Title__c,Account.Name,status__c, AccountId FROM Contact WHERE AccountId IN : acctIds AND RecordTypeid = '012D6765454BaFA']){
          WebServiceCallout.sendNotification(con.Id,con.Email,con.FirstName,con.LastName,con.phone,con.Title__c,con.Account.Name,con.status__c);
        }
    }
	}
}
