Normally, the Title Authentication module is used as an API to log users in to your publications with their username/password on your system.
However, the same tool can be used to harvest emails.
We have a built-in hosted script so you don't have to host your own. What this script will do is send you an email with the user's email address.
The settings are as follows and you can reference the screenshot below:
1: How would you like to use the Remote Security API?
Choose "remote script on my site"
2: Your remote login script to POST to:
http://www.mygazines.com/clients/generic_emailer/you@domain.com (replace "you@domain.com" with your email address)
3: string returned on success:
enter value: "success"
4: username field name:
enter value: "email"
5: password field name:
check box for “not needed”
Remote Authentication - Email Harvesting - Title Setup

You can then enter any custom message you like (this field can include html if you wish to add an image or logo)
finally the website field can presumably be set to your home page (or left blank)
Now when users load any issue with these settings, they’ll be prompted to enter a single field - their email address. If it’s a properly formatted email, they will gain access to the issue and you will receive an email with their email address
That concludes our "built-in" email harvesting, but of course you can host your own script that does much more with the entered email, such as adding it to your database as a "lead".
