External services

Google reCAPTCHA

This plugin can optionally use Google reCAPTCHA v3 for spam protection when the site administrator enables reCAPTCHA and enters Google reCAPTCHA keys in the plugin settings.

When reCAPTCHA is enabled for a form, the plugin loads the Google reCAPTCHA script from www.google.com on pages where that form is displayed. When a visitor submits the form, the plugin sends the reCAPTCHA response token, the configured secret key, and the visitor IP address to Google’s siteverify endpoint to validate the submission. The plugin also offers an administrator-only secret key check that sends the configured secret key and a test response token to Google.

Google reCAPTCHA is provided by Google LLC. Terms: https://policies.google.com/terms Privacy Policy: https://policies.google.com/privacy

Installation

Upload the plugin folder to /wp-content/plugins/ or install it through the WordPress admin.
Activate the plugin from the Plugins screen.
Open Forms in the admin and create a new form.
Copy the shortcode from the form editor.
Insert the shortcode into a page, post, or compatible page builder.

FAQ

Does the plugin send data outside my website?: By default, no. Submitted messages are stored locally in the WordPress database and emails are sent through wp_mail() or your configured SMTP server. If Google reCAPTCHA v3 is enabled, the reCAPTCHA token is verified through Google reCAPTCHA.
How do I insert a form into a page?: Copy the shortcode from the form editor, for example [mailfix_form id="123"], and paste it into a page, post, or compatible builder.
Where do I configure email notifications?: Open Forms > Notifications, choose a form, and configure recipients, sender details, the admin notification, and the optional thank-you email.
What personal data does the plugin store?: The plugin stores submitted form fields, submission date, an IP hash, and the user agent for administration and basic security checks. The IP hash is not a readable IP address. If Google reCAPTCHA v3 is enabled, the verification token is checked through Google reCAPTCHA.
How can I test email delivery?: Open Forms > Notifications, choose a form, and send a test email. The result is stored in the mail log. A sent status means WordPress accepted the email for sending; actual delivery still depends on the mail server and domain DNS.
Does the form work without JavaScript?: Frontend submissions are designed as AJAX forms and require JavaScript in the visitor’s browser.
