How to programmatically retrieve all leads from a mailing list?

Yes. That is a start. But how do I query mailing lists / lead?

It seems maling lists are located in home/groups and leads in home/users but what indicates whether the node is a mailing list or a lead?

And rather than querying JCR, I would much more prefer to do this using an API. I've been looking through http://docs.adobe.com/docs/en/aem/6-0/develop/ref/javadoc/ but still haven't figured out if/how to retrieve leads. NewsletterEmailService.createMailingList(String groupName, Session session) and then figure out how to get the group name?

Hi There,

Thanks for reaching out to Adobe Community.

You might want to look at the below link which talks about programmatically accessing content through JCR API.
