Is Cold Email Right for Your Business?
Find out in 60 seconds. Your Total Addressable Market (TAM) is simply how many potential customers exist for your business. We'll calculate it and tell you if there's enough for cold email to work.
The minimum: You need at least 5,000 companies in your market. About half won't have valid emails or suitable contacts — so 5,000 becomes ~2,500 usable leads.

Why 5,000 Companies?
Approximately 50% of companies won't be usable after filtering — no valid email found, no suitable decision makers, or they don't actually meet your requirements upon closer inspection.
From 5,000 companies in your search, expect around 2,500 high-quality, actionable leads with verified emails and matched decision makers.
