This plugin adds a 'sendgrid' command to Heroku's CLI client, making it possible (and easy) to view your email usage during the current month.
Luckily, Heroku's client makes it very easy to install plugins:
heroku plugins:install git://github.com/hone/heroku-sendgrid-stats.git
For the current month:
$ heroku sendgrid
+----------------------------------------------------------------+
| date | requests | bounces | clicks | opens | spamreports |
+----------------------------------------------------------------+
| 2010-12-01 | 12342 | 12 | 10223 | 9992 | 5 |
| 2010-12-02 | 32342 | 10 | 14323 | 10995 | 7 |
| 2010-12-03 | 52342 | 11 | 19223 | 12992 | 2 |
| Totals | 97026 | 33 | 43769 | 33979 | 14 |
+----------------------------------------------------------------+
The command also accepts the optional parameters year= and month=. For example:
$ heroku sendgrid month=6
+---------------------------------------------------------------+
| date | requests | bounces | clicks | opens | spamreports |
+---------------------------------------------------------------+
| 2010-6-01 | 0 | 0 | 0 | 0 | 0 |

...
| Totals | 0 | 0 | 0 | 0 | 0 |

$ heroku sendgrid year=1970 month=1

| date | requests | bounces | clicks | opens | spamreports |
