There is a CRM tool called Cloze, ( https://ai.cloze.com/platform/ ) which has a feature that I am a big fan of. It lets you connect your phone and pulls all communications in so that when tracking relationships and you open a contact it shows you all your interactions with them across email, slack, text messages, or mobile calls.
It also lets you set categories of relationship types, and set a time to remind you to reach back out to them. IE 6 months for a donor, bi weekly for x type of contact, 3 months for y type of contact.
It is a feature that given ClickUps desire to replace all other bizz tools, is powerful enough of a feature to consider as it brings an incredible amount of consolidated insight to relationships which, are the foundation of any sucessful endeavor in life, are they not?
(I was lost as to what category to list this under...)
