If you would like to add an email link, you will need to add "mailto:" before you add the email address. Here is how.

1. Click and highlight the text you would like to add the link to.

2. Click the "Text Link" block from the panel on right.

3. When the widow opens, add "mailto:" followed by the email address you would like the emails to be sent to.

4. While you are in edit mode, all links are disabled. Once you save your campaign, click preview, click on your link to test.
