What does adding existing customers as referrers mean?

Which ways can I add existing customers?
- Upload a list when you have a one-time or occasional batch of customers. See How Do I Upload a List of Customers and Generate Referral Links for Them?
- Sync from a CRM when your customer records are already maintained in a supported CRM. See How Can I Sync Your Referral Program With Your CRM?.
- Use Zapier, Make, n8n, or another supported automation route when a customer event in another system should trigger the handoff. See How Can I Add Referrers Automatically From Other Apps?.
- Use a custom API workflow when your own product or customer system needs to control the handoff.

When should I use an upload?
When should I use a CRM or app connection?
When should an existing customer become a Referrer?
What happens after customers are added?
How do I choose the right route?
- Use Upload for a controlled list and a one-time import.
- Use CRM Sync when records should be selected and mapped from a supported CRM.
- Use an app automation when the same handoff will happen repeatedly.
- Use another supported integration when the customer data or event lives in a system that needs to pass the person into the campaign.
- Use the API when your product or customer database needs a custom integration.
What should I check before inviting the audience?
- Confirm that the people belong in the campaign and that you have permission to contact them.
- Test with one or two records before importing or automating the full audience.
- Decide which referral method you will promote: referral link, QR code, direct lead submission, or a configured Stripe promo code.
- Decide how customers will access their referral experience and how you will deliver their referral information.
