Follow the steps listed in our "Adding a Link to a Page" article.
In the URL field, you will add the following, with no spaces:
- mailto: << add this immediately before the email address you'd like the email to go to
- email@example.com << your email address
When users click this link, a blank email will open in their preferred email program.
Note: there is a browser setting that disables these types of links from triggering an email. These email links will not work for visitors to your site that have disabled these types of links. In our experience, those visitors are the minority!
