There are several posts regarding dynamic fields and campaign variables:
Campaign Variables are only available in Corporate Marketer packages or within the agency portal
Campaign Variables are used exactly like Dynamic Fields, the difference being that custom rich content can be pulled out of a campaign and into a variable. The idea is that if you are doing one type of campaign over and over, with a few blocks of content being the only thing that changes from one campaign to another, extract the content into a Campaign Variable.
Campaign Variables are defined in the campaign interface under the 'Variables' tab:
The basic format of referencing a Campaign Variable is
The Campaign Variables are typically accessible via a content block editor by clicking on the tag icon.
As an example, consider a webinar campaign. Not much changes from webinar to webinar, hence pull out the variable data into a campaign variable. Things like presenter bio, topic, images, etc can all be extracted into Campaign Variables. The date of the webinar ... is a great example of a place for a campaign variable.
The date variable (for example %CAMPAIGN.EVENT_DATE%) can be used to auto-redirect the registration page to a 'view the recording' page by using Campaign Variables.
In the example above, this was used %CAMPAIGN.EVENT_DATE% + 0.5.days for the redirect date. Note, similar to Dynamic Fields, that date math can be used.
The format for date math is
%CAMPAIGN.TOKENS(SOMEDATE).VALUE% + 3.days
%CAMPAIGN.TOKENS(SOMEDATE).VALUE% - 1.week
So: the form is %VARIABLE% [+-] [0-9].[days|weeks|months|years]
The date format of the Campaign Variable is dd/mm/yyyy ... with time dd/mm/yyyy hh:mm:ss (24 hour clock)
Campaign Landing pages can be reference by using the format "NAME_NAME2_NAME3". The landing page named "Register For Webcast" is referenced in the example above as REGISTER_FOR_WEBCAST. This does not work well if you name all of your pages the same in a campaign. Thus the page is reference by
