so I have a link in my email that points to a landing page that I created in exacttarget. I want to capture the email address and save it to a data extension, I also need a date created field in the data extension. Is there anybody know how to do that?
Pass over a query string parameter (you can encrypt this if you like using AMPScript) The URL will look something like http://linktolanding.com/page.aspx?qs=qwerty&email=%%EmailAddr%%
In your landing page you can retrieve the value by using RequestParameter()
%%[ SET @email = RequestParameter("email") InsertData("Data Extension Name", "Email", @email) ]%%
As for creating a date created field in the Data Extension - just navigate to the Data Extension and add a new column called date created with a data type of date and check the box to use today's date as the default. That way you won't need to include a date stamp in the AMPScript function.
