How to Troubleshoot Common Hubspot Form Problems
When a Hubspot form stops working correctly, you can miss critical leads and lose visibility into your marketing performance. This guide walks you step by step through diagnosing and fixing the most common form problems so your tracking, submission data, and automation stay reliable.
Before You Start: Key Hubspot Form Checks
Begin with a quick series of checks to confirm whether the issue is with your Hubspot form configuration, your page, or external tools.
- Confirm which page and form are affected.
- Check if the error happens for all users or just some.
- Test in an incognito or private browser window.
- Disable browser extensions temporarily.
If the problem persists, follow the targeted troubleshooting steps below.
How to Verify Hubspot Form Submissions
Sometimes visitors say they filled out your form, but you see no corresponding record. Use these steps to confirm whether Hubspot actually received the submission.
Check Form Submissions in Hubspot
- In your Hubspot account, go to Marketing > Lead Capture > Forms.
- Hover over the form name and click Actions > View submissions.
- Use filters such as date range or page URL to locate recent submissions.
If submissions appear here, your form is working and the issue may be with workflow enrollment or list criteria, not the form itself.
Confirm Contact Creation in Hubspot
- Navigate to Contacts > Contacts.
- Search by the email address your visitor used.
- If no record appears, click Filters and add a filter for Form submission to see if the form was submitted under a different email or as a duplicate.
If you find a matching record, review its Activity timeline to confirm that the Hubspot form submission is logged.
Diagnose Hubspot Form Display and Embed Issues
When a Hubspot form does not appear or looks broken on your page, the problem is often related to the embed code or external scripts.
Check the Hubspot Embed Code
- In Marketing > Lead Capture > Forms, hover over your form and click Share.
- Copy the embed code exactly as provided.
- Paste it into your page or template HTML without altering the script.
If you use a CMS or page builder, make sure you are placing the embed code into a dedicated HTML or code block, not a rich text field that might strip or escape scripts.
Review Conflicting Scripts and Ad Blockers
Certain browser extensions and privacy tools can block Hubspot form scripts. To rule this out:
- Test the page in an incognito window with no extensions enabled.
- Try another browser or device.
- Ask a colleague on a different network to test the same URL.
If the form loads in one environment but not another, the issue is likely related to third-party blocking, not the Hubspot form itself.
Fix Missing Fields and Property Problems
Another common issue is that fields appear differently than expected, or the data captured by your Hubspot form does not populate properties as intended.
Verify Field Mappings in Your Hubspot Form
- Open the form editor from Marketing > Lead Capture > Forms.
- Click a field and check the Property it is mapped to on the left panel.
- Confirm you are using the correct contact property for your reporting and workflows.
If you changed a property after creating the form, review and update the mapping for that field so Hubspot stores incoming data correctly.
Check Dependent and Progressive Fields
If some fields only appear for certain visitors, you may be using dependent fields or progressive fields.
- In the form editor, review each field for dependency rules.
- Check whether progressive fields are set to replace previously captured information.
- Test the form using a fresh browser session or a contact that has never submitted the form to view all potential fields.
Adjust settings if important fields are hidden too often or from the wrong contacts.
Troubleshooting Hubspot Forms on External Pages
Hubspot forms embedded on non-Hubspot pages can introduce additional complexity, such as script conflicts and cross-domain tracking issues.
Verify the Page URL and Tracking
- Open your page and view the source code.
- Confirm that the Hubspot tracking code is present if you rely on analytics and attribution.
- Ensure the domain is connected to your Hubspot account for accurate reporting when possible.
Without tracking, submissions can still reach your CRM, but page view data and analytics may not match your expectations.
Use Browser Developer Tools to Inspect Errors
If the Hubspot form does not load or throws visible errors, your browser console often reveals the cause.
- Open your page in Chrome.
- Right-click and select Inspect, then switch to the Console tab.
- Reload the page and look for JavaScript errors related to form scripts or blocked content.
You can share any error messages with your developer or a Hubspot consultant to speed up the fix.
When Hubspot Automation Does Not Trigger After a Form
Sometimes the form works and submissions appear, but expected workflows, emails, or internal notifications do not fire.
Confirm Enrollment Triggers in Hubspot Workflows
- Go to Automation > Workflows.
- Open the relevant workflow and review the enrollment trigger.
- Ensure the trigger includes the exact Hubspot form you are troubleshooting and the correct criteria, such as date range or number of submissions.
If contacts appear in your form submissions but not in workflow history, your enrollment criteria may be too narrow or misconfigured.
Check Notification Recipients and Settings
For internal notification emails that never arrive:
- Open the form in the editor and click the Options tab.
- Review the Send submission notifications to list for valid email addresses.
- Verify that recipients can receive external emails and that messages are not being filtered as spam.
If needed, test by adding an alternate address and submitting the form yourself.
