🔍 How Kanbox finds emails
Kanbox does not extract emails from LinkedIn, as very few professional emails are visible there.
Instead, it uses:
The first and last name of the contact
The company name or domain
Then, it:
Guesses the most likely email pattern
Checks if the guessed email exists using mail servers
🧩 Why enrichment may fail
Low match rates often occur when your list includes:
Freelancers or individuals with no listed company
Local businesses with limited online presence (e.g. restaurants)
Companies without a known domain name
➡️ In these cases, there’s no way to guess or verify a professional email.
✅ When results are highest
You’ll get the best enrichment rates when targeting:
Mid-size to large companies
Tech-oriented or digitally active organizations
These lists can reach 70%+ match rates.
