title: Dynamic content in email templates
body: <p>I have rails background and i'm working to implement something like as shown in the image<a href="https://i.stack.imgur.com/R0yK9.png" rel="noreferrer"><img src="https://i.stack.imgur.com/R0yK9.png" alt="enter image description here"></a></p>
  
  <p>My email template will have such tags. While sending the email to the client, his information will get filled up in the template. I found this link <a href="https://stackoverflow.com/questions/27540118/dynamic-values-in-email-template">here</a> but there's no answer. I looked up and found <a href="https://github.com/code-and-effect/effective_email_templates" rel="noreferrer">this</a>gem, however i cant use it as it uses liquid templates and i was unable to implement it because of time limitation.</p>
  
  <p>I know i can do the whole thing of finding <code>{{first_name}}</code> and replacing the content whenever a tag appears but i doubt if its an efficient way to implement it.</p>
  
  <p>Please share your ideas and guidance. Thanks in Advance :)</p>
