Unsubscribe from Campaigns

In Email

All emails sent from Campaigns will have an unsubscribe link embedded automatically. If a person unsubscribes from Campaigns, this will prevent that person from getting any further emails from the Sandstorm Product that emailed them.

Bulk Upload

If you wish to sync up your unsubscribes between other tools, please use the attached CSV file to upload people who should be unsubscribed from Campaigns emails. Note that this will unsubscribe users from all future Campaigns.

The attached CSV is preformatted with the event and property required to unsubscribe a person from Campaigns.

IdentityTimestampEventProp:KM Subscription Status

KM Unsubscribed


Add the Identity of the person you wish to unsubscribe, along with the unix timestamp for the date and time you are uploading. You can convert the current date and time to unix here: https://www.epochconverter.com/

Once you have properly formatted your CSV file, please follow the steps here.


If you wish to unsubscribe people in real time as they unsubscribe from other tools you may have, please trigger this event and property as they unsubscribe from other tools.

These are:

  • Event = KM Unsubscribed

  • Property = KM Subscription Status: Unsubscribed

Using the HTML Editor

In order to send an email from Campaigns using the HTML editor, you must provide an unsubscribe link somewhere in your email.

Please use the following format:


<a href="%%KM_UNSUBSCRIBE_LINK%%">Unsubscribe</a>

This will take your user to the page where they can unsubscribe.


You can change the text for Unsubscribe to anything you like, as long as the href is present in the email.
