GDPR Do Not Track Option
How does a site visitor set ‘Do Not Track’?
How does Sailthru’s ‘Do Not Track’ designation work?
The ‘gdprDoNotTrack‘ JS function requires that Sailthru.init() be called on the page and takes no parameters. The function will look for the sailthru_hid cookie automatically in order to identify the user and store their ‘Do Not Track’ designation on to their profile. Should the user not have a sailthru_hid to identify them, Sailthru will create a sailthru_hid cookie and designate it as ‘do-not-track’.
Additionally, all cookies used for tracking purposes are purged and will not be created for ‘Do Not Track’ users:
- sailthru_content – content viewed
- sailthru_pc – personalized content clicked on
- sailthru_bid – source email, used for purchase attribution
- sailthru_sid – sailthru identifier
- sailthru_cid – content viewed
- sailthru_rid – Concierge and Scout clicked personalized content
- sailthru_recommendation_hidden – Concierge close designation
Sailthru does retain and record data after a user has chosen to opt out of tracking, however that data contains no identifiable information about the user. Data exchanged after the ‘Do Not Track’ designation has been set includes general engagement metrics (like the number of page views) and anonymous personalization calls.
‘Do Not Track’ and Suppression Lists
Users opted out of online tracking have no engagement activity (opens, clicks, or pageviews) attributed to them. If you are using an engagement-based suppression list, they will eventually cease to receive your messaging as their activity is not being tracked.
For example, with a suppression list of users who haven’t opened or clicked in the last 180 days, any user opted out of online tracking will be suppressed after this timeframe, regardless if they’ve continued to engage with your email.
