Check if someone replies to my email in Gmail using Google Apps Script

Question

Is there a way wherein I can track if someone replies to my email using appscript? Because I have this google sheet that serves as my tracker if my email is sent & if someone replies to my email.

Answer 1

Would be good to have some code as a place to start:

In summary:

Each message has an Id and for each message exist a threadId that groups all the messages from the same thread. So first you have to know this threadId.

If you want to track a reply over a message you have two options:

• Look for every incoming message to see if they have the same threadId

• Look for a certain threadId and see if contains more messages than the last time you'd check it

Apps script: thread.getMessages()

In any case the way to go is to setup an automated script that runs every certain time checking any of the two options.
