Google Gmail Sending Limit

According to a post from Google Groups, the Google Apps Team sent an email to a user on Gmail's sending limit. The email is as below.

Here is a list of some of the sending limits in place on your account:

- 500 messages per day (i.e., you can hit 'Send' a maximum of 500
times)
- 500 unique recipients
- 2000 total emails (for example, you could send one message to a
group of 500 people four times)

Please note that there may be additional factors which slightly raise
or lower these limits, but this should be a good general guideline.

Sincerely,

Joanna
The Google Apps Team
