Thanks William, looks like I am limited to the "add to specific list" due to my subscription level. The click trigger is available on the next tier subscription.   I'm already creating a list of recipients who do click...   I think I'll put together a quick dummy email and send it to myself for testing.   [Edit] Just sent myself a test message and then clicked repeatedly on the target link. Waited a while and clicked again.   I received exactly one follow up email, at the expected time following the click.   Using this approach, by the way, allows me to avoid sending people a follow up multiple times over separate newsletters. I can always reset the list and start fresh... Thanks!   Lee ... View more
