I use a funnel site within social media ad campaigns that populate into constant contact. However, when the contact information arrives in an email list, I don't know about it. Then I have an autorespond email sent back to them immediately.
With that said, I have to visit either site constantly to see if ppl have arrived. So if Constant contact could develop a way that I got an email when a person arrived in a SPECIFIC list, at that moment. That would be perfect!
Or add a CC field to the auto responder that I could add my address. Either way would alert me that someone has arrived. (List Specific though)
I know that I can get Daily, weekly, etc. updates. But instant would be great too.
