Lemlist + Attio at a glance
Lemlist integrates with Attio through OutboundSync. Email sends, opens, clicks, replies, bounces, and unsubscribes, plus connection requests, social messages, and replies, are written as Notes on the matching Attio Person, with the related Company. An optional OutboundSync custom object adds structured records for lists and views. The OutboundSync team guides onboarding.

| Setup | Guided: the OutboundSync team runs onboarding |
A Note on the Person is easy to read and hard to filter. OutboundSync writes every Lemlist step as a Note for reading, and can also create an OutboundSync record per event in an optional custom object. Those records are what Attio lists and views sort on, so outreach becomes something you can count.
Use it to see which channel is working. A view grouped by event type shows how many People replied by email versus social this month, and a list of Lemlist leads marked Interested gives founders and reps one place to start the day.

Yes, for lightweight automation. Zapier, Make, and n8n are good for prototypes and simple routing, but they need ongoing maintenance and bill by task or step.
