MailChimp Autopost Updates to Subscribers

Hello,

We are using MailChimp to handle EasyBlog subscribers. Our requirement is depicted below -

1. We have multiple Blog Categories (EasyBlog)
2. Users can Subscribe to those Blog Categories
3. Whenever there is an blog update to Categories, users who have opted in for those Categories should receive an automatic email update via MailChimp

I hope this can be achieved using Mailchimp. Can some one let me know how to implement this feature?

Also, if there is an alternate technique (without using MailChimp), please do share them here.

Thank You in Advance!
