Subscription link

Actually not, we do have not such kind of link. Anyway, if you are sending that invitation by email, you can import all contacts in the Newsletter plugin with the status “not confirmed” and send an email t ask to confirm they want to be subscribers.

That is something similar to what described in this article (without setting not confirmed all your already collected subscribers):
