Automatically find verified business emails for your LinkedIn leads with Kanbox’s Email Finder.

Updated over a month ago

✉️ One email credit per address found

The Kanbox Email Finder uses one credit for each verified professional email address. You only pay when we deliver a valid result — no waste, no guesswork.


🧠 No use of LinkedIn emails — only verified business emails

Kanbox does not rely on LinkedIn profile emails, as those are rarely public and often personal.

Instead, Kanbox uses multiple trusted enrichment providers to search for verified business emails, through a structured, privacy-compliant process.


🔍 How does email enrichment work?

Let’s take an example:

  • Last name: Poirot

  • First name: Sophie

  • Company: wikipedia

Kanbox will try different combinations like:

Each format is tested against the company’s mail servers. If one combination doesn’t trigger a server error, it’s considered a valid business email.


🚀 Where can I launch an email search?

You can search for professional emails from several places within Kanbox:

  • in the inbox, when selecting one or more members — an action menu appears at the top,

  • on a member’s chat window,

  • from an imported list,

  • in the Lead Manager.

  • from a pipeline or an automation campaign pipeline.


✅ In short

Kanbox helps you find verified business emails automatically, with no scraping of LinkedIn addresses, and using real-time validation on company servers. Fast, accurate, and built into your prospecting workflows.
