[Fixed] Webflow Forms Not Sending Emails

Quick Answer: Webflow forms often fail to send emails because of internal spam blocklists, unsubscribed notification emails, or unverified "From" addresses. To fix this, verify that your email isn't on the Webflow blocklist by contacting support, re-add "unsubscribed" addresses in Site Settings, and ensure you aren't using role-based emails (like info@). For 24/7 reliability, use a heartbeat monitor like FormWatch to detect silent failures instantly.

Webflow is a powerhouse for design, but its native form handling has a "black box" problem. Many users discover too late that their forms have been silently failing for weeks, even while the website appears to be functioning perfectly. This guide covers the high-intent fixes for the most common Webflow delivery issues.

1. The "Internal Blocklist" Nightmare

Unlike other platforms, Webflow manages its own mail delivery reputation. If a notification email sent to you bounces once - or if a teammate accidentally clicks "Unsubscribe" in a notification email - Webflow may permanently block that email address from receiving future leads without telling you.

• The Fix: Go to Site Settings > Forms. Check the "Send form submissions to" field. If your email is missing, re-add it. If it’s there but you aren't getting mail, you must contact Webflow Support specifically to ask if your address has been added to their internal suppression list.

2. Role-Based Email Rejection

As of 2026, many major mail providers have tightened security on "role-based" addresses. If you are sending Webflow notifications to info@yourdomain.com or support@yourdomain.com, there is a 40% higher chance they will be flagged as bulk spam and deleted before they reach your inbox.

The Fix: Switch your notification recipient to a name-based email (e.g., john@yourdomain.com). This simple change often bypasses the aggressive "silent" filters of Microsoft 365 and Google Workspace.

3. The reCAPTCHA "Submission Spin"

If your users report that the "Submit" button just spins or shows an error, it’s likely a reCAPTCHA version mismatch. If you enabled reCAPTCHA in Site Settings > Apps & Integrations but didn't actually drag the reCAPTCHA element onto your form in the Designer, Webflow will block the submission entirely.

4. Custom Form Action Bypass

A common mistake during site migrations is leaving a "Custom Action URL" in the Form settings. If there is any text in that field, Webflow stops processing the form and stops sending you notifications. It assumes you are using a third-party tool like Mailchimp or Zapier to handle the data.
