About the Book
This book is the user guide for the Email Confirmation 2.0 plugin for Grails.
Email confirmations are needed in some form in many web applications. Whether you are confirming a user's email address is valid during a signup process, authorising an action that requires higher than normal security, or offering opt-outs or other toggles via links in email.
In this short but comprehensive book the author of the plugin explains in depth how to use this plugin to:
- Send email confirmations to users for any purpose
- Receive callbacks when users confirm
- Receive callbacks when confirmations time out
- Use multiple confirmations for different functions
- Customize the email templates
