Is there any plugin which restricts the wordpress content / posts and shows a popup for the newsletter and only allow when someone successfully subscribed to the site via Mailchimp newsletter.
Thanks Leo, More like https://en-gb.wordpress.org/plugins/opt-in-panda/ but with supportability with the mailing list of Jetpack. Till now i could not find any plugin so far. Can you please let me know if there are any alternatives.
