[your-email] ! Unsafe email config is used without sufficient protection.

that warning is not about your message text πŸ‘
It’s a Contact Form 7 security warning and very common. Here’s what it means and how to fix it properly.


❗ Why you’re seeing this warning

You have this in Mail (2) β†’ To:

[your-email]

CF7 flags this as unsafe because emails are being sent directly to user-input email addresses without verification. This can be abused for spam if not protected.


Step 1: Keep To as [your-email]

Step 2: Add this in Additional Headers

Paste exactly this:

Reply-To: [your-email]

βœ” This tells CF7 the email is intentional
βœ” Warning usually disappears
βœ” Improves email deliverability


BEST PRACTICE SETUP (Industry Standard)

Mail (2) settings should be:

To

[your-email]

From

SEO Tool King <noreply@seotoolking.com>

Additional Headers

Reply-To: noreply@seotoolking.com

πŸ‘‰ This makes it clear the email is system-generated and safe.


EXTRA STRONG FIX (If warning still shows)

Enable one of these:

  • Contact Form 7 β†’ reCAPTCHA
  • Or use Flamingo plugin
  • Or install an SMTP plugin (VERY recommended)

Best SMTP plugins:

  • WP Mail SMTP
  • FluentSMTP
  • Post SMTP Mailer
