The problem: when I run a script from my gmail account the ‘from’ in the email shows the email address name, not the account name. So, it displays ‘john.smith2024’, not ‘John Smith’.

Background:

I developed an app script which sends emails to a list. I shared the app script with another Gmail account I own to test the script and because I ran against the email quota (100, I believe) in the primary account.

So:
Gmail-primary
Gmail-secondary

In Gmail-secondary I further developed the script and made it so that it could run the script and send the emails seemingly from my primary email (set up the primary as an alias in Gmail-secondary account email settings).

The problem: when the script is run from either account (Gmail-primary or Gmail-secondary) the ‘from’ in the email shows the email address name, not the account name.
