Sync HeyStream attendees to Mailchimp audiences

Connect Mailchimp to send HeyStream registrants, attendance activity, tags, and selected registration fields into your audience.

Overview

Connect Mailchimp to keep your HeyStream broadcast audience in step with your email marketing. New registrants and attendance activity can flow into the audience you choose, ready for segmentation and follow-up.

Use the Mailchimp integration when webinar signups, product demos, or live launch attendees should become part of the same campaigns and customer journeys your team already runs in Mailchimp.

What syncs to Mailchimp

  • Contact details, including email address, first name, and last name
  • Selected registration fields from each attendee's signup record
  • The selected audience for synced contacts
  • Configured tags for synced contacts
  • Broadcast registration and attendance activity events

How it works

When someone registers for or attends a HeyStream broadcast, HeyStream updates the matching Mailchimp contact.

Your integration settings control which audience, tags, and registration fields are included when contacts sync.

HeyStream also sends registration and attendance activity to Mailchimp, giving your team clearer signals for timely follow-up.
