Newsletter plugin with button function

I’m currently developing a website for a client, and i need to setup the newsletter. The problems is that i need a newsletter function with a button in a fixed position on the page, because the visitors need to be able to reopen the newsletter once it has been closed and vice versa. I got the idea from the messenger button down in the left corner from --> I am then looking for a plugin that has a similair solution, too what the messenger button does on their website.

Hi @KevinBJ

You can search here you will find Contact buttons Item there

Those are JS plugin. If you need to know anything to be clear about any Item just ask the Author through Item page support Tab.
