@Erin Piquero we may need more information to help you with this, could you share a little more about the goal?
Are you trying to create an audience to send emails to people who signed up on an Unbounce landing page? And do you know if you are passing any information to Intercom already from Unbounce as custom attributes?
You can use tags but if you already have data from Unbounce in Intercom you could also use this to build the audience as well.
If you aren't already passing data from Unbounce to Intercom it seems you could use Zapier for this and most likely add the info on which landing page or campaign they should be receiving.
Create or update Intercom users from new Unbounce form submissions
Feel free to share more about your goals here or in a DM and I'll be happy to point you in a good direction or feel free to book a call on my calendar and let's look into it together, this sounds interesting.
