I use Clay (https://clay.earth/) but haven't used it much as I found the search was lacking (my primary use case is searching for contacts that fulfill X criteria)

UPDATE: Thanks for the comments so far. To clarify my situation:
My main use cases are: Gmail (personal): For personal contacts. Gmail (work): For professional contacts related to my role. Outlook (work): For internal and external business communication. LinkedIn: Managing professional connections. Messaging apps (WhatsApp, Messenger, etc.): Keeping in touch with a wide range of contacts.
I’ve tried syncing across these platforms using Google Contacts, vCard exports, and a few automation tools, but the results have been inconsistent. Either the syncing doesn't work as expected, or there’s a lot of manual cleanup involved—especially when contacts change roles or details across different apps.
I’m wondering if anyone has found a more seamless way to manage contacts across all these different contexts? I’d love to hear any recommendations for more advanced tools, automations, or strategies that have worked for you.
