In the list type List<Id> you are trying to add Conids.add(mail.Email) which is giving you the error: Invalid id: vivekravi@gmail.com

@Vivek

  Try below Code...

<pre>
public PageReference send()
    {
     public List<Id> Conids=new List<string>();
        List<Contact> contacts=[Select Id,Email From Contact Where AccountId='001i000000g7erl'];
         Conids.add(Trigger.New[0].Id);
 
        Messaging.MassEmailMessage emails=new Messaging.MassEmailMessage();
        emails.setTargetObjectIds(Conids);
        emails.setTemplateId('00Xi0000000J9hx');
        emails.setsubject('note');
        emails.setplainTextBody('body');
      
        Messaging.SendEmail(New Messaging.MassEmailMessage[] {emails});

return null;
}
</pre>
