You can create an html body instead. You also need to modify your MailApp.sendEmail() function to include htmlBody in the arguments.

Here is the solution:

var email_body = 
      `Dear ${mailData.name},  <br/>
      Thank you for writing to us. We have received your message about ${mailData.subject}. <br/>
     and will get back to you within 24 hours. Until then, you can give us an email [email protected]. <br/>
     Thank you <br/><br/>`
  
  MailApp.sendEmail( {to:mailData.email, subject:mailData.subject, body:email_body,htmlBody:email_body}); // subject

Note that <br/><br/> will generate two new lines and <br/> will generate one.
