When someone adds themselves to a group that is configured as a mailing list they get sent an email with a confirmation link. The email includes the token: {subscribe.url}
We now have something like 2500 people in our database that have joined a mailing list but not confirmed, so they are in a 'pending by email' status. We want to run a campaign to encourage them to confirm their subscription, but the {subscribe.url} token doesn't appear to work in a standard CiviMail mailing.
We can't be the first to have come across this issue. How can we effectively encourage all of these people to confirm their subscription?
