Gmail Send Quota, When Sending Using Google App Engine

Gmail imposes a daily 500 recipient quota for sending emails. If you send through their POP/IMAP interface that quota is only 100 recipients per day.

What is the sending quota for sending an email on a gmail account using the google app engine? Would it follow the POP/IMAP limit or the standard gmail limit?

Here is all the official gmail quota information I found: http://mail.google.com/support/bin/answer.py?hl=en&answer=22839

Solution

  • The answer depends on how you decide to send the email.

    • Are you using the built in App Engine mailing API? If so you, can send lots and lots of emails (see amir's answer).
    • Are you sending your mail through Gmail's SMTP server? ( I assume you meant SMTP when you said POP, as POP is only for reading email) If so, the limit is 100, as you state.
    • Is your app connecting to gmail through http and pretending to be a human using the normal interface? Then the 500 limit would apply.
