Integrations

Ken + Attio Integration

Ken sends five email events (sent, clicked, replied, interested and unsubscribed) to the matching Attio person through OutboundSync, a partner app that supports Attio in beta, in near real time.

What the Integration Does

In short Sends Ken email events to Attio through OutboundSync, one way.

Ken does not connect to Attio directly today. OutboundSync, a partner app, receives Ken's webhooks and writes each email event as a Note on the matching Attio person. It matches by the email address in each event.

Your team sees sends, clicks, replies, interested leads and unsubscribes in the person's Notes in Attio, next to the rest of your sales activity.
