some CRMs have built-in dedup and I think it's crucial - should be based on fuzzy match taking into account multiple elements (not only first name / last and email but also phone, url, and fuzzy match on names)
I'm a bit biased Nimisha as I'm the founder of www.folk.app, which is also a CRM product. i know we've invested a lot in making deduplicate work and it's a super complex algorithm. I know it's often a part products don't invest enough time on
