Hello James,

There could be several reasons why emails sent from the Contact Form 7 plugin in WordPress are not being received. Here are a few possible solutions you can try:

1. Check the spam folder: Sometimes, emails sent from Contact Form 7 can end up in the recipient's spam folder. Ask the recipient to check their spam folder and mark the email as not spam if it is found there.

2. Check the email configuration: Make sure that the email address and settings in the Contact Form 7 plugin are correct. Go to the Contact Form 7 settings and double-check that the email address and other details are correct.

3. Use a different email address: If the recipient's email address is a free email service like Yahoo, Gmail, or Hotmail, try using a different email address for the recipient. Free email services can sometimes block emails sent from WordPress.

4. Use an SMTP plugin: Consider using an SMTP plugin, like WP Mail SMTP or Easy WP SMTP, to send emails from WordPress. These plugins can help ensure that emails are sent from a reliable email server and can reduce the chance of emails being marked as spam.

5. Contact the hosting provider: If none of the above solutions work, contact your hosting provider to see if there are any email issues on their end that may be causing the problem.

Personally, I use WP Mail SMTP with Contact Form 7, and it works fine.

I hope It will help you.
