# Using merge fields to personalize your emails

Merge fields allow you add in subscriber info into your email for a personalized experience. You can view a list of all available fields by clicking the respective tab anywhere you are adding email content.

Mailblast uses  [liquid](http://shopify.github.io/liquid/basics/introduction/) to handle merge fields, so on top of inserting tags for users, you can set up additional filters and conditionals in your emails templates.

For example you can:

* Set a default value
  * Dear {{ first\_name | default: "customer" }}
* Capitalize only the first letter
  * Dear {{ first\_name | capitalize }}
* Get only the first word of first\_name (If your first and last names are not split)
  * {{ first\_name | split: " " | first }}

The full liquid reference is available [here](http://shopify.github.io/liquid/basics/introduction/).
