What the prospecting suite covers

A cold email campaign is only as good as its list. These tools cover the steps before the first send: deciding who to sell to, sizing the market, and checking the emails on the list before you send.

Define the market

The ICP generator reads your website and writes the industries, company sizes and titles your buyers have. The TAM calculator counts how many companies and people match. Company lookup shows what Ken knows about a single company from its domain.

Check the emails

The email verifier checks syntax, MX records, disposable and role addresses before you send. The ESP checker shows how much of a list sits on Google, Microsoft or other mail hosts, which decides how you warm and split your inboxes.
