Brilliant @d-neri. Simply, brilliant.

Nice one

Beautiful script!

Well, beside permissions, the user's actual email must be substituted for "" in line 15.

Otherwise,
Error
GoogleJsonResponseException: API call to gmail.users.messages.list failed with error: Invalid user id specified in request/Delegation denied
sender_list_paged @ sender_list.gs:15

Wonderful script! Thanks @d-neri

I seem unable to approve permissions, it lets me click on my gmail account after clikcing 'Review Permissions' but then comes back with "This App is Blocked as it tried to access sensitive information in your Gmail account"
Is there something else I need to complete

i received this error: "Exception: Too many simultaneous invocations". Would be grateful for any advice to solve this. thanks

The script worked nicely.
Thanks.

Thank you very much for the wonderful script. I am getting an "Exceeded maximum execution time." error. Can anyone suggest a fix for this?

Any help would be greatly appreciated. Thank you.

You can use this script instead- https://gist.github.com/fabianem/5012c0b9b44d0bd2c167ab7c81a82937
