Look at the link - does it have a token on it to identify that particular survey invitation as the one they sent you? I'd wager that's what happened rather than it being some deeper tracking. A stock standard survey monkey survey can do the same thing.
The link may have an identifying code in it, that was custom generated just for you, and would be different in emails sent to other Anker customers. It would not matter from which device or IP address you viewed it from, if the URL has identifying information in the URL parameters.
Most likely just a unique link.
Makes you wonder about their products…
