# Product update - 3.20.2018 - Data Extensions
Data Extensions allow you to connect values from your contacts with additional data, such as assigned agent information and preferred store information.
These extensions are a great way to not only manage your separate lists of information, but insert that information into your creative for more personalized content - the type that converts.
For example, let's say you have a contact with Vaughan Mills as their favourite store, ID #503. An extension gets created called Store Information, which has records that might look like the following:
| Store\_id | Store\_name | Store\_address | Store\_phone | Store\_email |
| **503** | Vaughan Mills | 123 Street Rd. | 123-123-1234 | vmills@domain.com |
| **208** | Richmond at the Hills | 536 Road St. | 321-321-4321 | rhills@domain.com |
Using these records, you can display any of the information related to the Vaughan Mills store in your message.
