Is it just me, or is adding existing leads to a newsletter a catch-22 because the web-to-leads form is going to collect new leads (and doesn’t actually add them to anything).
In other words, how can a database of hundreds of already inputted leads be sent an invitation to opt-in to a newsletter? There is no customer self-service, manage subscriptions, features… is there?
In a campaign e-mail, the Leads should have an easy link to opt-in to a news letter (which I assume also means a contain campaign for that newsletter).
