Is there any Well developed Plugin for getting subscribers list ?

Hi mates

I want to increase my subscribers but i don;t know coding . Is there any way or plugin with that help i can get subscribers. I apply many plugin but most of all fake and spam subscribers. I just want to add related subscribers something customized which clearly indicating just Doctors or professors can be subscribed for free newsletter or news updates.

Check out Leadpages.net - it's not cheap because you have to pay a monthly subscription but it's very effective.
