Hi,

You need to choose either static newsletter and you can use macros - since you have the subscriber context available or, the dynamic newsletter where you have it basically on the web page - but then the visitor is just a public user and you do not have the subscriber context to use the macros.

Or, you can create a custom functionality - the link to the live page from the e-mail will contain e.g. a querystring with the subscriber ID which you can read on the page and personalize the content. However, this requires customization.

Best regards,
