Hi, 
This is my trigger code:
    if(trigger.isAfter && trigger.isInsert){
        List<Messaging.SingleEmailMessage> emails = new List<Messaging.SingleEmailMessage>();
        EmailTemplate emtemp = [SELECT Id from EmailTemplate WHERE Name = 'Email Notification'];
        System.debug('em temp'+emtemp);
        for (EM_Event_Team_Member_vod__c addedmem : Trigger.new) {
            
            Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();
            email.setTargetObjectId(addedmem.Team_Member_vod__c);
            email.setTemplateId(emtemp.Id);
            email.saveAsActivity = false;
            emails.add(email);
            
        }
        
        Messaging.sendEmail(emails);
    }
This is the email template:
<messaging:emailTemplate subject="Addition of Team Member" relatedToType="EM_Event_Team_Member_vod__c">
<messaging:HTMLEmailBody >
