Plugin and confirmation to subscribers


I’ve searched all over the web and couldn’t find my answer.

I’m quite newbie with php and I only use it to send a monthly newsletter. What I need right now is to send a confirmation to every subscribers to make sure they still want to get information from our Foundation. Basically I want a «Confirm» button in the note I’m gonna send them.

I saw that there were plugin allowing this, but I’m using phplist online and I can’t find where to add the plugin (is it even possible on the online version?)

Any help would be appreciated ! Thanks !

By “using phplist online” do you mean phplist hosted?
If so then you will need to raise this as a support request through your account. You are not able to install plugins with phplist hosted, only to use those that are already installed.
