Real-time email alerts for standard Gmail users

I’m working on a project to sync new Gmail messages with a Google Sheet. My goal is to use real-time notifications to update the sheet instantly when a new email arrives. But I’ve hit a snag.

The notification system I want to use only works with special accounts, not regular Gmail. Is there any way to get live email updates for normal Gmail users?

Update:

Thanks for the feedback. Let me explain better. I can set up the backend stuff fine. The tricky part is getting permission from the user.

For normal web apps, there’s an easy way to ask the user to let the app access their email. It looks like this:

auth_setup = email_auth.Setup(secret_file='app_info.json', permissions=['read_mail'])

But for the live update system, I can’t find a similar way to ask for permission. I’m trying to connect this permission step with the live updates. Let me know if you need more info!

I’ve faced similar challenges with Gmail notifications. One approach that worked for me was using IMAP IDLE. It’s not exactly real-time, but it’s pretty close and works with standard Gmail accounts.

You’ll need to keep a persistent connection open to the IMAP server. When new emails arrive, the server notifies your application. It’s more efficient than polling and doesn’t require special permissions.

For implementation, you can use libraries like imaplib2 in Python. Here’s a basic example:

import imaplib2, threading

def idle_loop(connection):
    connection.idle()

imap_connection = imaplib2.IMAP4_SSL('imap.gmail.com')
imap_connection.login('[email protected]', 'your_password')
imap_connection.select('INBOX')

threading.Thread(target=idle_loop, args=(imap_connection,)).start()

This method has served me well in projects requiring quick email notifications. It might be worth exploring for your use case.

As someone who’s worked extensively with Gmail APIs, I can tell you that real-time notifications for standard Gmail accounts are tricky, but not impossible. Have you looked into using Gmail’s push notifications with Cloud Pub/Sub? It’s a bit complex to set up, but it can provide near real-time updates.

Alternatively, you could implement a polling mechanism using the Gmail API. It’s not instant, but with a short polling interval, it can be pretty close. I’ve used this method before, polling every 30 seconds, and it worked well for most use cases.

Regarding permissions, you’re right that it’s more complicated for push notifications. You might need to use OAuth 2.0 for authorization and request additional scopes. The ‘https://www.googleapis.com/auth/gmail.push’ scope is what you’re looking for.

Have you considered using Google Apps Script? It can trigger functions on email arrival and might be simpler to implement, though it has some limitations. Just some thoughts based on my experience - hope this helps!

hey, have u tried a webhook? i set up an endpoint on my server and gmail delivers realtime updates there. it’s a neat way to get mail notifications. not too heavy on code skills. might be worth a shot!
