+## Wrapping Text
+
+You can write blog posts using e-mail with the help of SENDGRID API, like so:
+```javascript
+sgMail.setApiKey(process.env.SENDGRID_API_KEY);
+      let msg = {
+        to: '<your-name>@blogger.com',
+        from: '<your-name>@gmail.com',
+        subject: title,
+        html: html,
+      };
+     sgMail.send(msg);
+``` 
+You can also wrap the text in the HTML to make a multi-line blog post:
+```javascript
+<div style="white-space: pre-wrap;"> 
+<code>        int a = 10;
+              int b = 10;
+              int d = 10;
+</code>
+</div>
+```
