This extension provides integration for SendGrid with Preside's email
centre. Using this API we can send the mails over send grid API.
Currently, the extension provides: * A Message Centre service provider
with API key from the Send Grid * A Send Grid webhook endpoint
(/sendgrid/hooks/) for receiving and processing send grid webhooks for
delivery, failed, & bounce notifications, etc.
From the root of your application, type the following command
> box install preside-ext-sendgrid
