D7 Lead Finder is what we refer to as a "B2B Database" tool. Much like the other tools on this list, it involves a central database containing contact details for all kinds of businesses, which can be queried by users for a fee.
It allows users to search for leads based on various criteria such as industry, location, company size, and more. The tool claims to have a database of millions of contacts that can be easily accessed and exported for use in outreach campaigns. Additionally, D7 Lead Finder offers features such as email verification, domain search, and contact enrichment to further streamline the lead generation process.
