<a href="https://wordpress.org/plugins/jetpack/" rel="ugc">Jetpack</a> makes it easy to add contact forms to your WordPress site, but you may want a simple way to add a <a href="https://www.google.com/recaptcha/" rel="nofollow ugc">Google reCAPTCHA</a> to prevent spam. This plugin will manipulate the Jetpack <code>[contact-form]</code> shortcode to prepend the Google script, add a button, and parse the response.
This plugin allows both reCAPTCHA v2 and invisible reCAPTCHA (see screenshots and choose whatever works for you!).

<li>Include user info in auto reply (name, email address, message content, etc.)</li>
</ul>

Jetpack Contact Form Auto Reply

Works as it should in 4.9.8; I like that you can use {Field labels} in subject/message :)

Two changes would make this not just good, but great:


	 ability to have a subject/message per contact form (since you may have several forms with differing fields on the same site)
	the settings should be in the editor, where you define the fields (that would make the UI simple for keeping auto-reply-settings specific to one form)




Almost perfect

Send an automatic reply to anyone who fills in your Jetpack contact form
