This sample demonstrates how to use SendGrid on Google App Engine standard environment.

See the sample application documentaion for more detailed instructions.

For more information about SendGrid, see their documentation.

Before you can run or deploy the sample, you will need to do the following:

1. Create a SendGrid Account. As of September 2015, Google users start with 25,000 free emails per month.
2. Configure your SendGrid settings in the environment variables section in src/main/webapp/WEB-INF/appengine-web.xml.
3. Visit /send/email?to=YOUR-EMAIL-ADDRESS

You can run the application locally and send emails from your local machine. You will need to set environment variables before starting your application:

$ export SENDGRID_API_KEY=[your-sendgrid-api-key]
$ export SENDGRID_SENDER=[your-sendgrid-sender-email-address]
$ mvn clean jetty:run
