✓ What We Access
We only read form submissions (response data, email addresses if collected, submission timestamps) to match with your email campaigns. We never modify forms, sites, or submissions.
Step 4: Track Campaign Lead Generation
- Navigate to your Dashboard
- Click the + New Report button
- Select your email platform and campaign
- In the Leads section, select Webflow
- Email Calculator will automatically match form submissions to campaign recipients

💡 How Lead Matching Works
We match Webflow form submissions to email campaign recipients by email address within a configurable time window after the campaign was sent. This lets you attribute leads and calculate campaign-driven conversion rates.
Lead Metrics You'll Get from Webflow
Lead Generation Metrics
- • Total Leads / Form Submissions
- • Lead Conversion Rate (% of recipients who submitted)
- • Coverage (% of recipients matched to submissions)
- • Leads per Email Sent
- • Submission Timestamps
- • Lead Email Addresses (when collected in form)
- • All Form Field Data (contact info, custom fields, etc.)
Common Questions
Why isn't my API Token working?
Make sure you've copied the complete API token without any extra spaces. Ensure the token hasn't been revoked in your Webflow account settings. Verify you're using a token with the correct permissions.
How do I find my Form IDs?
You can use the Webflow API to list all forms on your site. Call GET https://api.webflow.com/v2/sites/{site_id}/forms with your API token. Alternatively, form IDs may be visible in your form settings in the Webflow Designer.
How does email-to-lead matching work?
We match Webflow form submissions to email campaign recipients by comparing email addresses. Your Webflow form must include an email field for matching to work. Submissions within your configured attribution window (e.g., 14 days) after the campaign are attributed to that campaign.
What if I don't see any leads or submission data?
Verify that your Site ID and Form IDs are correct. Ensure your Webflow forms collect email addresses. Check that you have form submissions within the selected date range. Make sure the API token has proper permissions and hasn't expired.
Is my form and respondent data secure?
Yes. We only request read-only access to form submissions. We extract email addresses and submission timestamps for matching purposes. Your API token is encrypted and stored securely. You can revoke access at any time from your Webflow account settings.
Can I disconnect my Webflow account later?
Yes. You can disconnect Webflow at any time from your Email Calculator Settings page. Click the trash icon next to your Webflow integration. Your existing lead attribution data will remain in your reports, but new submissions won't be tracked.
Does this work with Webflow CMS forms?
Yes, this integration works with standard Webflow forms. For advanced CMS-powered forms or custom form implementations, you may need to verify that submissions are accessible via the Webflow Forms API endpoint.
