I have a small business, we send newsletters informing about our publications every now and then. The newsletters have links to our articles, and I would like to know which recipients read the articles through the newsletters and to manage the subrscribers more automatically. Can anyone suggest of a service, e-mail plugin or a self-made system to implement this? Currently, we just have our own manual database of recipients and send an identical mail to each person ourselves via Outlook.
