I am really struggling to see this tool as a good one to use.
Only 3 emails folders can be linked.
I see a difference between lots of leads vs real opportunities - so I load both as Contacts but not sure if I would bother creating a deal every time.
I used to find it great, but we are moving away to One Page CRM for managing prospects and leads, and Woodpecker for cold email.
Could you use tags to differentiate your leads and opportunities?
