Preview Mode
Test your campaign in preview mode before making it live for real visitors.
Preview mode lets you test your campaign on a private URL before publishing to production. This ensures everything works correctly without risking the experience for real visitors.
What Is Preview Mode?
When you publish to preview:
- A private preview URL is generated
- Only people with the URL can access it
- Production domains are not affected
- You can update preview as many times as needed
Preview URLs are unique to your campaign and don't appear on your production domains. Share them only with team members who need to review the campaign.
