How can I troubleshoot form submission emails not being received by the client on a Webflow-hosted site?

If a Webflow form submission email is not being received by the client, the issue typically lies in spam filtering, incorrect email entries, or limitations in Webflow’s form handling. Here's how to troubleshoot effectively:

1. Verify Form Settings in Webflow

• Go to Project Settings > Forms and check the email addresses listed under Form Notification Settings.
• Ensure the client’s email address is spelled correctly and there are no extra spaces or characters.
• If using multiple addresses, separate them with commas.

2. Check Spam or Promotions Folder

• Ask the client to check their spam, junk, or promotions folders.
• Mark the Webflow notice email as “Not Spam” to help train their provider’s filter.

3. Add Webflow Sender IPs to Allowlist

• If the client uses a strict spam filter (Office 365, Gmail for Business, etc.), ask their IT team to allowlist Webflow’s sender addresses and IPs:
• Webflow sender email: no-reply@webflow.com
• Sender IPs may vary, but Webflow occasionally uses SendGrid, so inquire with Webflow support or check mail headers for clues.

4. Turn Off Email Forwarding Rules

• If the form emails are forwarded from one address to another, that can fail silently or get flagged by spam filters.
• Ensure form submissions go directly to the target inbox, not through forwarding chains.

5. Use a Third-Party Form Handler (Optional)

• If issues persist, consider using Zapier or Make (Integromat) to connect Webflow forms to external services like Gmail or Mailgun.
• You can also embed a form from Formspree, Typeform, or Jotform to improve reliability and gain logging features.

6. Test with Alternate Email Addresses

• Temporarily set the form notification to a known-working email (e.g. your own Gmail).
• Submit the form and confirm delivery. This helps determine if the problem is tied to the client’s domain.

7. Check Submission Data in Webflow

• Go to Project Settings > Forms > Form Submissions to confirm that Webflow is receiving the form data.
• If it’s listed there but no email reached the client, the issue is almost certainly on the delivery end (spam filtering, allowlisting, etc.).

8. Confirm Webflow Plan Limits

• On Starter (free) plans, you only get 100 submission notifications per month.
• Submissions beyond that limit will still be saved in the dashboard, but email notifications won’t be sent.

Summary

To fix missing Webflow form emails, double-check the notification email settings, inspect the client’s spam filters, and allowlist no-reply@webflow.com. If problems persist, test with alternate email addresses or switch to a third-party email delivery service for better reliability.
