Still working in WordPress 4.9.6 and JetPack 6.1.1 :)

I didn’t get the plugin to work at first. JetPack was sending email but Auto Reply didn’t send anything. I even installed the plugin “WP Mail Logging” to see emails sent by WordPress and enabled a debug log to no avail.

For me, the solution was getting the label for the email field right.

The plugin states “[…] including the field label like this: {Field name} – e.g. {Name} […]”.

My JetPack contact for was like this:

[contact-field label="E-mailadres" type="email" placeholder="Jouw e-mailadres" required="true" /]

(in the visual editor, it’s the field label you see on top of the field)

At first, I setup Jetpack Contact Form Auto Reply Settings for “Email address field” to the case sensitive:

{E-mailadres}

That didn’t work. What did work was leaving the {} out, like this:

E-mailadres

Hope this saves other people some time ??
