Yes, Jeto can update your emails and landing pages with different values based on your segmentation. Say, for example, you want to make your email title dynamic by geographical region (and you have 6 different regions: North America, South America, Europe, Africa, Asia, Australia), you would have 6 different tokens in Marketo and 6 different fields in Jeto to store the value of each:

Title - North America
Title - South America
Title - Europe
Title - Africa
Title - Asia
Title- Australia

The Collaborator would provide a value for each and the content will be dynamically updated based on the recipient's segmentation.
