What is App Engine Quota Email Admin?

Question

I am sending emails EmailMessage().send()from a Python App Engine application. After sending some test emails to my gmail addres, on the Quota Details page, I read the following:

Recipients Emailed   5%    5%    5 of 100     Okay
Admins Emailed       0%    0%    0 of 5,000   Okay

On the Permissions page, my email address is the only one specified and the owner.

I expected that the email addresses addressed to the application owner would fall into the "Admins by email" quota, and not into "Email recipients".

Here it says:

Email Addresses
The total number of messages for application administrators that were sent by the application.

What is an email administrator receipt for?

Answer 1

The package google.appengine.api.mailis a function send_mail_to_admins(sender, subject, body, **kw)that will send a letter to all administrators of the application and use of the quota Admin Emails, rather than general: Documentation .
