SendGrid-CodeIgniter Pack

This package allows you to send emails through SendGrid, store all the analytics data in your database and get spam reports to your database. You'll need a SendGrid account and CodeIgniter 2.0. There's a lot you can do with this. Using this pack, all the data and analytics will be in your database. I recommend adding another field to the database which will store user's ID, and will be identified by the email you're getting from SendGrid, This some of the stuff I do: If certain user's email Drops (Sendgrid response for emails that don't exists for example), I can handle it automatically by blocking him or flagging him in my app.
