I am creating an email campaign for a client using exact target, http://www.exacttarget.com/. The clients Salesforce account is already connected to their exact target account. I would like to make more personalization fields (marge fields) available within exact target using Salesforce fields. Currently I only have first name available.
Can somebody explain or provide me a link to some documentation. Web searches are not returning what I need
If Salesforce is integrated properly, then you should have a Salesforce tab enabled in the when you create a new Profile Attribute in Subscribers > my subscribers > Profile Management.
Once the profile attributes are mapped to Salesforce fields, then they will be available as personalization strings in your email:
%%[SalesForceField1]%%
