The link you clicked in my email added the Segmenting Tag GDPR Email Confirmation to your account.
You only need to click this link once per account, NOT once per list you’re on. You should only have received one copy of the email. If you received more, please create a ticket at the help desk and let me know which email addresses these went to, and which one you want to keep.
On the 25th of May, 2018, I will delete all accounts that do not include this Tag.
