Real time scenarios:- Write a trigger on Custom object (Registration__c) and Send a Custom Visualforce Component Email Template when Record is Created Condition is the Student Name should not be null.

Create Apex Class Trigger
Step 1:- Create Apex Class Trigger : sendCustmTemp.apxt

`TRIGGER sendCustmTemp ON Registration__c (BEFORE INSERT, BEFORE UPDATE, after INSERT, after UPDATE) {

IF(TRIGGER.isAfter && (TRIGGER.isInsert)){
FOR(Registration__c myEmail:TRIGGER.new){

 Registration__c stuReg = [SELECT id,Name, RegNewStudent__r.Name FROM Registration__c WHERE id=:myEmail.id];
         system.debug('myEmai444'+ stuReg.RegNewStudent__r.Name);

   IF(stuReg.RegNewStudent__r.Name != NULL){
       recipientsController.sendEmail(stuReg.id);
   }
}

}

}`

Create Apex Class controller
Step 2:- Create Apex Class : recipientsController.apxc

`public class recipientsController {

@AuraEnabled
public static void sendEmail(Id RegId){   //String toAddress, String Subject, String notes, String recId
  	Registration__c newRegistration = NEW Registration__c();
    newRegistration = [SELECT Id, Name, RegNewStudent__r.Name, RegCourse__r.Name, DateOfRegistration__c,sendSubjectLine__c, SendTemplateNote__c FROM Registration__c WHERE Id=: RegId];   
    DOUBLE UNIQUE= math.random()* 10000 ;
    String uniquestr = UNIQUE.format().remove(',').substring(0,4) ;
    string mil =  UserInfo.getUserEmail();
    string nm = 'test lastname' + uniquestr;
    Contact tempContact = NEW Contact(email = mil, firstName = 'test' +uniquestr, lastName = nm);
    INSERT tempContact;


    //Fetching Email template
    EmailTemplate templateId = [SELECT id FROM EmailTemplate WHERE Name LIKE 'emailNotifyTemp%' LIMIT 1];
    system.debug('templateId:: '+templateId);
   // string param1 ='<html>abcd</html>';       

    List<string> emailstr = NEW List<String>();
    //lstIdTO.add(UserInfo.getUserEmail());
    //emailstr.add('w3webmart@gmail.com');
    emailstr.add('w3webnet@gmail.com');
    list<Messaging.SingleEmailMessage> mail = NEW list<Messaging.SingleEmailMessage>();

    Messaging.SingleEmailMessage mails = NEW Messaging.SingleEmailMessage();
    mails.setTemplateID(templateId.Id);
    mails.setToaddresses(emailstr);
    mails.setTargetObjectId(tempContact.id);

    system.debug('Mails'+mails); 
    mail.add(mails);
    //system.debug('mail#105 >>'+mail);
    Messaging.sendEmail(mail); 
    //system.debug('Ten Value >>'+mail);
    //DELETE tempContact;

}

}`

Create Classic Email Templates
Step 3:- Create Classic Email Templates : emailNotifyTemp

`<messaging:emailTemplate subject="Registration Notification" recipientType="User" relatedToType="Registration__c">
<messaging:htmlEmailBody >

<c:regEmailTempVfc />

</messaging:htmlEmailBody>
</messaging:emailTemplate>`

Create Visualforce Component
Step 4:- Create Visualforce Component : regEmailTempVfc.vfc

`<apex:component controller="regTempController" access="global">

<table border="1" cellpadding="5" cellspacing="5" style="border-collapse:collapse;">
   <thead> 
      <tr>
          <td colspan="3"><span style="display:none;">Custom Label Img:-</span> <img src="{!$Label.w3webLabel}"  alt=""  align="left" width="134" height="60"/></td>
          <td colspan="3"><span style="display:none;">Documet Img:-</span> <img src="https://vijay3327-dev-ed--c.ap4.content.force.com/servlet/servlet.ImageServer?id=0156F00000IvXxw&oid=00D6F000000GGe0&lastMod=1572421120000" width="50" height="40"/></td> 

      </tr> 
     <tr style="background:rgb(0, 112, 210); color:#fff;">
         <th>Reg No.</th>
         <th>Student Name</th>
         <th>Course Name</th>
         <th>Date Of Registration</th>
         <th>Subject Line</th>
         <th>Template Note</th>
     </tr>
    </thead>
   <tbody> 
       <apex:repeat value="{!RegList}" var="regVar">
           <tr>
               <td>{!regVar.Name}</td>
               <td>{!regVar.RegNewStudent__r.Name}</td>
               <td>{!regVar.RegCourse__r.Name}</td>                   
               <td>
                   <apex:outputText value="{0,date,MM/dd/yyyy}">
                        <apex:param value="{!regVar.DateOfRegistration__c}" /> 
                   </apex:outputText>

               </td>
               <td>{!regVar.sendSubjectLine__c}</td>
               <td>{!regVar.SendTemplateNote__c}</td>
           </tr>
       </apex:repeat>
    </tbody>   
</table>

</apex:component>`

Create Visualforce Component Apex Class Controller
Step 5:- Create Apex Class : regTempController.apxc

` public class regTempController {

public static List<Registration__c> getRegList(){
    List<Registration__c> newRegistration;
      newRegistration = [SELECT Id, Name, RegNewStudent__r.Name, RegCourse__r.Name, DateOfRegistration__c,sendSubjectLine__c, SendTemplateNote__c FROM Registration__c ];   

      RETURN newRegistration;
}

}`
