I would like to be able to see a list of which contacts have opened an email in a Sequence. Filtering exists for many other metrics, but not for opens. It seems to be an obvious need - after all, when you use a Sequence, it is only logical to want to know who opened them. The overall open rate statistics are nice, but to close deals, I need to know which leads are opening the emails.
Please add such a simple filter. Apparently it exists in the Marketing Hub, so why not in Sales?
