1. Prepare and Import Leads to HubSpot

2. Verify the file format is supported by HubSpot (CSV, XLSX, or XLS).
3. Open HubSpot and navigate to CRM > Contacts.
4. Click the Import button on the top right.
5. Select the Import a file option.
6. Choose Quick import contacts only.
7. Click Choose a file, select your lead file, and click Open.
8. Click Next and map the columns by clicking the dropdown that says choose or create a property.
9. If you do not want to import data from unmapped columns, tick Don't import data in unmapped columns.
10. Click Next.
11. Name your import (e.g., "Register to webinar") and agree to the terms.
12. Click Finish Import.

2. Create a Static Segment from Imported Contacts

1. After the import, click the Actions button.
2. Select Add imported contacts to segment.
3. Choose New static segment from the dropdown.

8. Choose the action Register as attendee and select the specific webinar.
9. Click Save, then Review and turn on.
10. Set the option to enroll current contacts that meet the criteria to Yes.
11. Verify the number of contacts matches your imported leads and then click Skip and turn this on.
12. Finally, click Turn on the workflow.

Verify Registrations in Contrast

1. Open your Contrast account and select the specified webinar.
2. Click on Registrations to confirm that all imported contacts appear under registrations.

Common Problems and Solutions

What happens if a contact is already registered for the webinar?

Contrast will not create a duplicate registration. The contact will receive the confirmation email again if the workflow triggers the "Register as attendee" action a second time. You can suppress already registered contacts:

• Export existing registrations from Contrast.
• Import them into HubSpot.
• Create a suppression list of already registered contacts.
• Add that list as an exclusion condition in your workflow.

What happens if I accidentally import duplicate contacts into HubSpot?

HubSpot automatically deduplicates contacts based on email address. The same email will merge into one record, and the workflow will enroll the contact once unless re-enrollment is enabled.

Will contacts who unsubscribe from HubSpot emails still receive the webinar confirmation?

Yes, confirmation is sent from Contrast, not HubSpot.

Can I schedule the registrations to happen at a specific time?

Not directly during import, but you can:

• Add a delay step in the workflow before registering as an attendee.
• Schedule the workflow to turn on at a specific date and time.

Can I re-run this process later with a new list of leads?

Yes. For each new batch, import the new leads, create a new static list, and either create a new workflow or update the existing one to enroll the new list.
