Most contact form plugins are built for flexibility, with dozens of field types, conditional logic, integrations, and settings screens. That power comes with complexity, even for the simplest use case.
Micro Contact Form does one thing: it gives visitors a simple way to contact you. The form includes name, email, subject, and message fields. No setup required, no database tables, no clutter.
Add the shortcode [micro_contact_form] to any page, post, or widget and visitors can contact you immediately. Submissions are sent to your WordPress admin email address by default, or to a custom address configured in the plugin settings.
Provides a simple way for visitors to contact you without exposing your email address publicly on your site.
