To add an unsubscribe link in your email survey, write the text you want to use as a link and position and style it using the editor's tools.
Next you need to add the link - you will need to switch to code view and insert the the code [unsubscribe] so that SightMill can insert the survey's unique link for the particular recipient when sending out the email. Here's how to do this:
In your Project's Settings, click on the Email Survey Design menu
In the email editor write the text you want to use as an unsubscribe link and position and style it using the tools. For example 'Click to unsubscribe from future surveys'
Change to code view by clicking on the </> button to the left of the second row of icons at the top of the editor
Scroll through to find your unsubscribe text
Before the words you want to link, add in <a href=[unsubscribelink]>
After the words you want to link, add in </a>
So your sentence might look like this: 'Click to <a href=[unsubscribelink]>unsubscribe</a> from future surveys'
Change out of code view by clicking again on the </> button
Save your email by clicking the Save button
To add a link to a web-version of the survey, create a link and use the code [emailsurveylink]
