You can make links that open an email window when clicked, like this:
These are known as mailto links, and they are easy to make in WordPress.
Highlight the text or image that you want to make into a clickable email link. Click the Link button in the editor toolbar. In the link field, type:
Confirm the link and update or publish the page.
Now when visitors click the link their default email application will launch with the email address already filled.
You can even make your links include the subject line in the email. To do so, format your link like this:
mailto:email@example.com?subject=The subject for the email
