Community Q&A

How do I fix Contact Form 7 not sending emails?

Install an SMTP plugin like WP Mail SMTP to ensure emails are sent correctly, and check the ‘Additional Settings’ tab for any skip_mail functions.

Does Contact Form 7 have a built-in reCAPTCHA endpoint?

No, it uses the Google reCAPTCHA API directly. You must configure your API keys in the plugin settings under the Integration menu.

Can I use Contact Form 7 on a local development site?

Yes, but be aware that CF7 may automatically enable a skip_mail function in local environments; you may need to remove this in Additional Settings.
