How to Fix Contact Form 7 Blank Email Body (2026 Guide)

One of the most confusing Contact Form 7 problems is receiving an email notification with a completely blank email body. The email arrives successfully, but none of the submitted information—such as the visitor's name, email address, or message—is included.

This issue is usually caused by incorrect mail tags, mismatched field names, plugin conflicts, or email configuration problems.

In this guide, you'll learn the most common causes of blank Contact Form 7 emails and how to fix them.

Symptoms of a Blank Email Body

You may notice one or more of the following:

  • Email arrives with an empty message body.
  • The subject line is correct, but no form data appears.
  • Only some fields are displayed.
  • Uploaded file information is missing.
  • Confirmation emails are also blank.
  • The form submits successfully, but submitted values are missing.

Why Is the Contact Form 7 Email Body Blank?

Several configuration issues can prevent Contact Form 7 from inserting submitted values into your email template.

Common causes include:

  • Incorrect mail tags
  • Field names don't match
  • Deleted or renamed form fields
  • Plugin conflicts
  • Theme conflicts
  • Incorrect email template
  • JavaScript errors
  • Outdated Contact Form 7 version
  • SMTP configuration issues

1. Verify Your Mail Tags

The most common reason for blank emails is incorrect mail tags.

Each mail tag used in the email template must exactly match the corresponding field name in your form.

For example:

[text* your-name]

[email* your-email]

[textarea your-message]

Your email template should use:

Name: [your-name]

Email: [your-email]

Message:

[your-message]

If the field names don't match, Contact Form 7 cannot display the submitted values.

2. Check Field Names

If you've renamed or deleted form fields, update your email template accordingly.

Even a small spelling difference can result in blank values.

3. Review the Mail Template

Open the Mail tab inside Contact Form 7 and confirm that your message body includes the correct mail tags.

Avoid manually typing field names unless you're certain they match the form exactly.

4. Test the Form

After making changes, submit a test entry and verify:

  • Name appears correctly.
  • Email address is displayed.
  • Message content is included.
  • Attachments are listed.

5. Configure SMTP

SMTP doesn't usually cause a blank email body, but using authenticated email delivery improves reliability and prevents formatting issues.

Popular SMTP providers include:

  • Gmail SMTP
  • Microsoft 365
  • Amazon SES
  • SendGrid
  • Mailgun
  • Brevo
  • Zoho Mail

6. Disable Plugin Conflicts

Some plugins may modify email content or interfere with Contact Form 7.

Temporarily disable:

  • Email plugins
  • Security plugins
  • Caching plugins
  • Optimization plugins

Test your form after each change.

7. Check Theme Compatibility

Some themes modify WordPress email behavior.

Switch temporarily to a default WordPress theme and test your form again.

8. Update Contact Form 7

Running outdated versions of Contact Form 7 may cause compatibility issues with newer WordPress releases.

Always keep:

  • WordPress Core
  • Contact Form 7
  • Themes
  • Plugins
  • PHP Version

9. Store Form Entries

Even if an email is missing information, storing form submissions inside WordPress allows you to recover customer data.

This is especially useful for business websites where losing leads can affect revenue.
