How to Auto-Sync Attio Contacts to Lemlist Campaigns with Make.com
Every minute a new lead sits untouched in your CRM is lost opportunity. This Make.com automation eliminates manual transfers between Attio and Lemlist, ensuring your email sequences start the moment leads enter your pipeline—without any busywork from your team.
The Manual Transfer Problem
Sales teams using both Attio and Lemlist face a critical gap—leads captured in their CRM often sit for hours or days before entering email sequences. During this delay, prospect interest cools while competitors swoop in. Manual transfers between systems create:
- 37% slower response times compared to automated workflows
- Data entry errors from copying fields between systems
- Missed opportunities when busy teams forget to transfer leads
The hidden cost: For teams adding 50+ leads weekly, manual transfers consume 2-3 hours that could be spent selling. This Make.com automation reclaims that time while ensuring no lead falls through the cracks.
How the Automation Works
The workflow acts as a real-time bridge between Attio and Lemlist. When a new contact enters your specified Attio list, Make.com instantly:
- Detects the new entry via Attio's API
- Extracts all contact and company data
- Checks for empty company fields
- Adds the lead to your Lemlist campaign
- Includes custom field mappings you define
The entire process completes in under 2 minutes—faster than most sales reps could manually open both systems.
Setting Up the Attio Trigger
The automation begins with an Attio "Watch List" trigger. As shown at 0:45 in the video, you'll:
- Connect your Attio account in Make.com
- Select "Watch List" as the trigger type
- Specify the exact Attio list ID to monitor
- Set the trigger to fire on new entries only
Pro tip: You can find list IDs directly in Attio's UI by navigating to Lists → View List → Check the URL for the ID parameter.
Configuring Lemlist Actions
After capturing new Attio contacts, the workflow adds them to Lemlist with all relevant data:
- Personal fields: Name, email, phone mapped automatically
- Company data: Name, website, industry when available
- Custom fields: Any Attio properties you want included
The Lemlist "Add Lead" action (shown at 1:30 in the video) lets you specify:
- Which campaign to enroll the contact in
- Field mappings between Attio and Lemlist
- Default values for any missing information
Handling Empty Company Fields
Not all Attio contacts have associated company data. The workflow includes smart conditional logic (demonstrated at 2:15) that:
Checks for company existence: Before attempting to map company fields, the scenario verifies whether company data exists in Attio. If not, it skips those fields entirely.
This prevents failed syncs when company information is missing while ensuring all personal contact details still flow to Lemlist. You'll never lose a lead because one field was blank.
