Marketing parameters such as utm_ tags are something else: they tell a website where a visitor came from, but do not record the click by themselves. A HawkOpen tracking link records the click on HawkOpen’s side, rates it, and then forwards the reader.
As a sender: link tracking is off until your company’s owner or an administrator switches it on, and even then only recipients who consented to link tracking get tracked links. Before sending you can also switch link tracking off for a message or a campaign; links that do not start with https are never converted. As a recipient of an email tracked by HawkOpen, you can use the link “Do not track my activity” at the end of the message: opening it refuses tracking by that company at once and deletes what was measured about you before; the company cannot switch it back, only you can, on the same page.
Where rules that require consent apply, tracking may start only after that consent has been obtained. The link in the message lets the recipient withdraw consent later.
