how to use a newsletter with rainmaker

I’m not sure how a web hook works. What I would like is that when people sign up for my newsletter through rainmaker, that they be signed up for my newsletter plug-in, and then the newsletter can take over from there.

so all I need rainmaker to do is to capture the email addresses and then hand It over to the newsletter to take it from there.

Would a web hook work for that and how do I connect the newsletter with your plug-in?

I know you have options to connect to mail chimp, but I use a different service.

thanks
