WordPress Form Email Not Sending? Here's How to Fix It (2026 Guide)

One of the most frustrating issues WordPress website owners face is submitting a contact form successfully—but never receiving the email notification.

If your WordPress form isn't sending emails, don't worry. In most cases, the problem can be fixed in just a few minutes.

In this guide, we'll cover the most common reasons why contact form emails fail and show you how to fix them using VPSUForm.

Why Are WordPress Form Emails Not Sending?

There are several possible reasons:

  • Incorrect email notification settings
  • Your hosting provider blocks PHP mail()
  • SMTP is not configured
  • Emails are marked as spam
  • Invalid sender email address
  • DNS records are missing
  • Firewall or security plugins blocking emails
  • Incorrect form configuration

1. Check Your Form Notification Settings

The first thing to verify is your email notification settings.

Make sure:

  • The recipient email address is correct.
  • The "From Email" is valid.
  • The notification is enabled.
  • The subject line is configured.
  • The email template contains the correct form fields.

Even a small typo can prevent notifications from reaching your inbox.

2. Configure SMTP Instead of PHP Mail

Many hosting providers limit or completely disable PHP's default mail() function.

SMTP (Simple Mail Transfer Protocol) is the recommended way to send WordPress emails because it is far more reliable.

VPSUForm works with popular SMTP services, including:

  • Gmail SMTP
  • Outlook SMTP
  • Zoho Mail
  • SendGrid
  • Amazon SES
  • Mailgun
  • Brevo (formerly Sendinblue)

Using SMTP greatly improves email delivery rates.

3. Check Your Spam Folder

Sometimes your emails are actually being delivered but are placed inside the Spam or Junk folder.

If this happens:

  • Mark the email as "Not Spam."
  • Add your sender address to your contacts.
  • Use a professional domain email instead of a free email service.

4. Use a Professional From Email Address

Avoid using addresses like:

  • yourwebsite@gmail.com
  • yourwebsite@yahoo.com
  • yourwebsite@hotmail.com

Instead, use an email address that matches your website domain.

Example:

contact@yourdomain.com
support@yourdomain.com
info@yourdomain.com

This improves email authentication and reduces the chance of messages being rejected.

5. Verify DNS Records

Email providers often require authentication records to verify that your domain is allowed to send emails.

Important DNS records include:

  • SPF
  • DKIM
  • DMARC

Properly configured DNS records help improve deliverability and reduce the risk of emails being marked as spam.

6. Test Your Contact Form

After making changes:

  1. Submit your form.
  2. Check the admin email.
  3. Check the user's confirmation email.
  4. Review your spam folder.
  5. Verify that the form entry was saved.

7. Check Form Entries

If you're using VPSUForm, you can store submissions inside WordPress.

This allows you to confirm whether:

  • The visitor submitted the form successfully.
  • The problem is only with email delivery.
  • No data has been lost.

8. Protect Against Spam

Spam bots can overload your inbox and affect form performance.

Enable:

  • Google reCAPTCHA
  • hCaptcha
  • Honeypot Protection

These features help reduce fake submissions while allowing legitimate users to contact you.

9. Check Hosting Restrictions

Some shared hosting providers restrict outgoing emails to prevent abuse.

If emails are still not sending after configuring SMTP, contact your hosting provider and ask if there are any email sending limits or restrictions on your account.

10. Keep Your Plugin Updated

Running outdated plugins can cause compatibility issues with newer versions of WordPress or PHP.

Always keep:

  • WordPress updated
  • VPSUForm updated
  • Your SMTP plugin updated
  • Your PHP version current
