I believe that I'm not receiving a larger quota with my Google Workspace account. I reached my daily email quota on my regular gmail account.
I copied the google sheet; I renamed the function and file; I ran the script on my Google Workspace account. When I changed the script name, code, and associated email I was still unable to run it because Error: Exception: Service invoked too many times for one day: email.
See quota's here: https://developers.google.com/apps-script/guides/services/quotas
Perhaps you missed this note from the quota's link in the question:
Note: Additional limits apply for trial accounts. After you convert from a free trial account to a paid subscription, your account limits automatically increase when both of the following are true:
- Your domain has cumulatively paid at least USD $100 (or equivalent).
- At least 60 days have passed since reaching that payment threshold.
