Email Open Tracking
I would like to see (and would pay additionally for) a notifier when somebody opens my email. There are times when I send an email to somebody and I want to know in real time if they've opened it, or even if they are opening it at that moment. (A bit creepy, yes, but still valuable.) There are programs to do that (Yesware is one) and other CRM programs that are not as good as Insightly have that capability. But I would love to have that capability in Insightly.
