Connect Intercom in GrowSurf and choose the tag you want to sync

In Campaign Editor > 4. Options > Integrations, connect Intercom, authorize the account, select the Intercom tag you want GrowSurf to use, and save the integration.

Verify the GrowSurf attributes on a synced contact

Check a participant who already exists in both tools and confirm the Intercom contact has the GrowSurf fields you plan to segment with, such as growsurf_referral_status, growsurf_total_referral_count, and growsurf_next_milestone.

Build referral-focused audiences in Intercom

In Intercom Contacts or in a message's audience builder, add filters that use the GrowSurf data already on the record.

• Create a new-participant audience for people who have a share URL but no awarded referrals yet.
• Build a milestone audience from growsurf_next_milestone or the referral-count fields.
• Create a success audience for customers whose referral status already reflects awarded credit.

Reuse the same audiences across Intercom

Once the filters are stable, use those audiences in outbound messages, banners, lifecycle nudges, or support follow-ups so each referral ask goes to the right customer.

Spot-check the segment against GrowSurf

Before you send anything at scale, compare one or two records in GrowSurf and Intercom to make sure the same participant is landing in the right audience for the right reason.
