Why is my Webflow email form giving an error message for a valid email address input?

Your Webflow form may be rejecting valid email inputs due to issues with validation settings, spam protection, or restrictions on form submissions. Here’s how to diagnose and fix it:

1. Check Email Input Field Settings

• Go to Designer → Select the Email Input field.
• Check the "Element Settings" panel (gear icon).
• Ensure the input type is set to "Email".
• Look at any applied validation pattern—some custom regex patterns might be too strict.

2. Test Without Required Validation

• Temporarily remove the "Required" attribute from the email field.
• Try submitting the form with a test email (e.g., "test@example.com").
• If it works, the issue may be caused by form validation settings.

3. Inspect ReCAPTCHA and Spam Protection

• If using ReCAPTCHA, ensure it's set up correctly in Project Settings → Forms.
• Disable Webflow’s spam filtering temporarily to see if it's blocking certain email domains.

4. Check Browser Console for Errors

• Open your website in a browser → Press F12 or right-click → Inspect.
• Go to the Console tab and look for any JavaScript validation errors.

5. Test in Incognito Mode and Other Browsers

• Try submitting the form in incognito mode or a different browser.
• Extensions or cached settings might be interfering with validation.

6. Verify the Form Action URL (If Using a Custom Integration)

• If you're sending the form to a third-party service (like Zapier or Mailchimp), verify the Form Action URL in the Form Settings panel.

7. Check Webflow Form Submission Limits

• Webflow limits form submissions based on your plan. If you've exceeded your limit, the form may not work correctly.
• Check via Project Settings → Forms tab.

8. Test the Form on the Published Site

• Sometimes, forms work in Webflow’s preview mode but fail on the live domain.
• Publish your site and test the form there.

Summary

Your Webflow form might reject valid emails due to field validation settings, spam protection, custom scripts, or exceeded submission limits. Check your email field settings, disable spam filtering, test in incognito mode, and look at the browser console to find the issue.
