What do you guys think about email finder tools?

Hey everyone! I’ve been doing a lot of SaaS B2B outreach campaigns and wanted to get your take on email finder tools. Do they provide accurate contact details, especially when looking for business phone numbers and verified email addresses?

I'm looking for something that is easy to use and have been consulting various listicles and review sites like G2. I’m curious to know if anyone here has experience with email finder tools like Wiza, Clarity Check, FindyMail, Prospeo, etc.? One of the resources I checked out mentioned these tools (and I played around with them as they were embedded with the free versions within the resource), but I remain skeptical. Any recommendations, user reviews, or opinions will be highly appreciated.

The resource in question was "originally posted here.”
