My Email Shortcode is a plugin which adds a new shortcode [my-email] to your options. You can insert this shortcode at any place in your post’s or page’s main body and it will be automatically substituted by a link with your email address (with anti-spambot protection automatically included).
The shortcode takes the email addres from the post or page author’s profile, so whenever an author changes his/her email, the change will be automatically shown in all his/her posts and pages.
You can also add a default subject by adding a subject attribute like this: [my-email subject=”Subject”]. Whenever a person clicks on your addres, it will autoamtically set the subject of the message to the one you chose.

My Email Shortcode

If you often display your email address on your blog, this plugin is for you. If you change your address, it will apply the change in all places.

This plugin will allow you to completely customise the empty price HTML on a single product page. It can be used to add a ‘CONTACT FOR PRICING’ call to action button, 
some advisory text, or any custom HTML you choose.
There are three ‘content types’ available for flexibility & ease of use:
<ol>
<li>A simple text box with options for bold or italic styling</li>
<li>A button with an optional link</li>
<li>An option to add your own custom HTML</li>
</ol>
By default it will use the styles available in your custom theme, but each content type has a configurable CSS class, should you wish to style the content further.
Note on variable products:
The custom content will only show on variable products if none of the variations have a price set. Due to the nature of variable products, this will result in an out of stock message being displayed. If you do not wish to have this out of stock message, the simplest option is to only use this on ‘Simple’ or ‘Grouped’ products.

Custom Empty Price for WooCommerce

Show text, a call to action or custom HTML when a product has no price set.
