是否可以仅使用 JavaScript 而不使用 HTML 将动态链接插入到电子邮件中？ （使用 Google Script 发送电子邮件）

Question

Need to preface this with an edit, I'm not using Javascript in the actual email. I'm using Javascript in Google Script which I run to send the email.

I don't really know anything about using html/js in emails, but my roommate needed help inserting a dynamic link using JavaScript into his email using Google Sheets (a .gs file), so I found the code to do it, but the problem is the JavaScript still uses HTML for the dynamic link.

What I found was this

var str = "TEXT FOR LINK"
var link = str.link("http://LINKGOESHERE")

Running this works perfectly as it should. However, the rest of his email was entirely JavaScript, so JavaScript used this code to insert the following HTML code:

<a href="http://LINKGOESHERE">TEXT FOR LINK</a>

Since we are running this as a .gs file (Google Sheets), I was wondering if there was a way of just inserting the dynamic link without using any HTML at all, or if we simply need to wrap everything in HTML (and if so, how does that work with an email being sent by running a .gs file).

Here is what the .gs file looks like with the main text and info replaced with gibberish:

function sendEmails() {
var str = "TEXT FOR LINK"
var link = str.link("http://LINKGOESHERE")

var senderEmail = 'SOMEONESEMAILADDRESS@email.com';
link.onclick = function() {
    this.href = "mailto:"+senderEmail;
};
  var sheet = SpreadsheetApp.getActiveSheet();
  var startRow = 2; 
  var numRows = sheet.getLastRow()-1;
  var dataRange = sheet.getRange(startRow, 1, numRows, 2);
  var data = dataRange.getValues();

  var sender = 'MyName';
  var body = '\n\nTEXT BLABLABLABLABLA'+link+' TEXTBLABLABLABLA';
  var subject = 'SUBJECT';
  var options = {replyTo: senderEmail , from: senderEmail, name: sender};

  for (var i = 0; i < data.length; ++i) {
    var row = data[i];
    var emailAddress = row[0];
    var firstName = row[1];
    var message = 'Hi ' + firstName + ',' + body;


    MailApp.sendEmail(emailAddress, subject, message, options);
  }
}

You should not use javascript inside your emails. Most email clients do not allow execution of javascript since it is a strong security vulnerability. Some email clients like Outlook for example allowed it, but I am not sure if it still does or not.

Well even if there exists a client that runs javascript, sending emails with javascript is a huge red flag and your emails will be mostly rejected by mail servers.
