When Contact Form 7 stops sending emails in WordPress, it’s usually due to one or more of the following reasons:

Common Causes:

1. Hosting Restrictions – Some hosting providers block PHP mail functions, preventing WordPress from sending emails properly.

2. Incorrect Mail Settings – If the “To”, “From”, or “Subject” fields in the form settings are misconfigured, emails may fail to send.

3. Spam Filters – Emails may be sent but get caught in the recipient’s spam/junk folder.

4. Missing SMTP Configuration – Without SMTP, emails sent through WordPress may be blocked or marked as suspicious.

5. Plugin Conflicts – Other plugins may interfere with Contact Form 7’s email-sending functionality.

6. Outdated Plugin or WordPress Version – Using older versions of WordPress or Contact Form 7 can cause compatibility issues.

How to Fix It:

✅ Install an SMTP Plugin
Use a plugin like WP Mail SMTP to configure your site to send emails via a reliable SMTP service (like Gmail, SendGrid, or your hosting provider’s SMTP).

✅ Check Email Settings
Go to Contact > Contact Forms, edit your form, and review the “Mail” tab. Make sure:

• The “To” field contains a valid email address.

• The “From” field uses an email address from your domain (e.g., contact@yourdomain.com).

• No fields are left blank or incorrect.

✅ Test with a Default Theme and Plugins
Temporarily switch to a default theme (like Twenty Twenty-Four) and deactivate other plugins to rule out conflicts.

✅ Check Spam Folder
Ask recipients to check their spam/junk folder in case messages are being misclassified.

✅ Check with Your Hosting Provider
Some hosts limit or block outbound email. Confirm whether email sending is enabled on your server.

If these steps don’t resolve the issue, please contact your hosting provider or our support team for further help.
