plug in email list help

Hello,

My site: https://www.losangelessoccer.org

We use Gmail for our business emails. I was going to set up a email list subscribe button using Contact Form 7 plug-in on our WP website, however that will only send the person’s email address to my gmail. I will then have to add it to a group.

Here’s what I need: I need them to sign into an email list on my WP page, have that email address be automatically added to one of my gmail groups and then, when I send out a bulk email, I need my customer to have an option to UNSUBSCRIBE when they get the email.

What type of plugin or 3rd party software should I use to accomplish all this?

Thanks!
