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

If form submissions are working in Webflow but the client isn’t receiving email notifications, it’s typically an issue with the recipient address, spam filtering, or email server blocking. Here's how to troubleshoot it.

1. Check Form Submission Settings in Webflow

• Go to Project Settings > Forms and verify that the correct recipient email is entered.
• Make sure the email address under Notification Email is spelled correctly and is active.
• Try replacing it with a different email address (like Gmail) to see if the issue is with the original receiving server.

2. Verify Submission Delivery in Webflow Dashboard

• From your Webflow Project Settings > Forms, scroll down to Form Submission Data.
• If the submission shows up there, it means the form is working and being processed.
• If the data is missing, the form may not be connected properly on the site or hasn’t been published with the form block.

3. Check the Recipient's Spam/Junk Folder

• Ask the client to check their spam or junk folder.
• If the email is there, whitelist form@webflow.com in their email client or server firewall.

4. Whitelist Webflow Sender Email in Client's Email Server

• Webflow sends submission emails from form@webflow.com.
• Instruct the client to add this to their email system’s whitelist or mark it as "not spam."
• If using a business email (e.g., hosted with Google Workspace or Microsoft 365), the IT admin may need to update the spam filter or email rules.

5. Avoid Email Forwarding or Group Aliases

• If you're sending to an email group alias or forwarding address, test sending to a direct user inbox instead.
• Group or shared inboxes often filter or block automated emails like Webflow forms.

6. Set Up a Custom Notification Workflow (Optional)

• For more reliable delivery, use Zapier or Make (Integromat) to create a workflow that sends submission notifications via a trusted email provider.
• This allows full control over the email’s “From” address and avoids default Webflow mail limits.

7. Check Webflow’s Email Limits

• Webflow has a daily email notification limit per site (100 emails/day on Lite plans). Exceeding this can cause delivery issues.
• You’ll still see submissions in the Webflow dashboard, but no emails will be sent.

8. Test With a Known Working Email

• Change the form notification to a personal Gmail or Outlook address temporarily.
• If the email arrives there, the issue is on the client’s mail server side, not Webflow.

Summary

If Webflow form submissions appear in the dashboard but notification emails aren’t received, confirm the recipient address is accurate, check spam folders, and whitelist form@webflow.com. Avoid group inboxes, and use Zapier for more reliable email delivery if needed.
