Capturing your audience into Attio (Signal Sync)

What this does

When a Signal finds someone engaging with content you're monitoring, Signal Sync does one of two things:

If they already exist in Attio — their engagement is written as a note on their existing Person Record. No duplicate created. Their record gets richer.

If they're new to Attio — a fully-enriched person is created with 65+ fields, verified email, verified mobile number, and their engagement history. Optionally added to an Attio list automatically.

This distinction matters. Signal Sync isn't just a lead generation tool — it's a way to make sure every meaningful engagement with your content is captured and contextualised in your CRM, whether the person is already in your pipeline or completely unknown.

The most popular use case: your own content

The most common Signal Sync setup monitors your own brand's posts and your team's posts. Anyone who reacts to or comments on your content is captured:

• A follower who liked your founder's post last week → now in Attio with their full profile

• A prospect who commented on your product announcement → existing person updated with that note

• A customer who engaged with your case study → CS team can see the signal before renewal

By the time someone fills out a form, you've often already missed the window. Social engagement happens earlier — when they're thinking about the problem, not actively searching for a solution.

Other Signal types that work well

• Competitor posts — capture people engaging with competitor content, signalling they're evaluating options

• Keyword Signals — capture people writing about pain points your product solves

• Hashtag Signals — capture people engaged in your industry community

Setting up Signal Sync on a Signal

Signal Sync is configured on individual Signals — not in the Attio integration settings. Any Signal with contact enrichment enabled can push to Attio.

Step 1 — Enable contact capture on your Signal

Open a Signal and go to the Configure step (or Export Options). Enable at least one contact capture option:

• Capture Post Author as Contact

• Capture Post Reactions → Save Profile as Enriched Contact

• Capture Post Comments → Save Profile as Enriched Contact

Step 2 — Go to the Integrations step

In the Signal wizard, navigate to the Integrations step. You'll see a grid of connected integrations. Click Attio.

Step 3 — Configure Attio sync

In the Connect your Signal to Attio card:

Create or update people in Attio — toggle this on to enable the sync.

Add to a new or existing Attio list (optional) — select an existing list or create a new one. People are added to this list when created.

Advanced export options:

• Export only verified emails — only push people where a verified email was found

• Allow export without email — push people even if no email is available

Sync Social Activity to Attio — when enabled, every reaction and comment captured by this Signal is written as a note on the matching person's Attio record. If the person already exists in Attio, this is how their record stays up to date with their engagement history.

Sync Engagement Counts — maintains running totals of reactions and comments per person in Attio number attributes. Select which Attio number attribute to use for reaction counts and comment counts.

Step 4 — Save the Signal

Save the Signal. From the next run, people are created or updated in Attio as enrichment completes.

Deduplication

Before creating a new person, the platform checks whether they already exist in Attio by matching their LinkedIn URL and email address. If a match is found, no duplicate is created — only a note is added to the existing record.

Using AI Agents to qualify before pushing to Attio

For high-volume Signals, consider adding an AI Agent before the Attio push. The agent can verify ICP fit, score the contact, or generate a personalised opener — and only push people who pass the qualification to Attio. This keeps your CRM clean.

See the AI Agents collection for prompt examples and setup guidance.

Note: Attio vs HubSpot Signal Sync differences

Attio Signal Sync does not include owner assignment or sequence enrollment — these are HubSpot-specific features. Attio Signal Sync supports list assignment and engagement count syncing.
