I need help with Google Script

Job ID: 36319284

Budget: ₹600 – ₹800 INR

So I want to send mass number of cold emails using Google Sheet. I can either use Extension or script for that. And I am choosing to go with Google Script.

1. Now, I have the script. You need to check it whether it's valid or not or need some changes. If it needs some changes, you need to provide some changes.

2. I am also looking to add a few more features with the help of the script. So you should be able to do that too.
