Ken + Prospeo Integration

Add your Prospeo API key in Ken and every email Ken finds with it costs 0 Ken credits, because Prospeo bills your own account; lookups Ken covers when your key fails cost 1 credit ($0.02) per valid email.

What the Integration Does

In short Your own Prospeo key finds work emails for your Ken leads at 0 Ken credits.

Ken finds work emails for the leads in your campaigns. When you save your own Prospeo key, Ken sends those lookups to Prospeo on your key, so the emails it finds cost 0 Ken credits and Prospeo bills your Prospeo account instead.

Finds on your key stay free even when your workspace is out of Ken credits. If your key fails, runs out of Prospeo credits or hits a rate limit, Ken covers the lookup at its normal rate unless you turn Ken fallback off.

What Syncs

In short One-way: Ken calls Prospeo with your key.

How to Connect Prospeo

In short Connect Prospeo in 4 steps.

  1. Get your Prospeo API key

    In Prospeo, open the API page of your dashboard (app.prospeo.io/api) and copy your API key.

  2. Open provider keys in Ken

    In Ken, go to Settings, then Integrations. Under Email finders, open Prospeo and choose Add key. Only workspace admins can manage provider keys.

  3. Save the key

    Paste the key and save. Ken checks the key with Prospeo before storing it and confirms the account has credits.

  4. Choose the fallback

    Leave Ken fallback for email finders on so campaigns keep finding emails if your key fails, or turn it off to use only your own keys.

Use Cases

In short 3 ways teams use Ken with Prospeo.

  • Use Prospeo credits you already pay for instead of Ken credits for email finding.
  • Keep finding emails when the workspace runs out of Ken credits.
  • Run each agency client workspace on that client's own key.

Limits

In short Prospeo bills each lookup on your key under its own pricing.

  • Prospeo bills each lookup on your key under its own pricing.
  • Turn Ken fallback off and Ken makes no lookups of its own when your key fails, so those leads stay without an email.
  • Ken sends at most 60 lookups a minute to your Prospeo key per workspace, a conservative cap because Ken cannot see your Prospeo plan.
  • Keys belong to one workspace. Each client workspace needs its own key.
  • Only workspace admins can add, re-check or remove a key.
