# Personalize content with Liquid

> Use Liquid merge tags to insert user properties, unsubscribe links, and dynamic content in your messages.

## Inserting imported audience data

In Vero, we use a prefix within the standard Liquid template fields to denote where to load the data from.

`{{user.property}}` replaces the attribute with the name of any customer property that you've captured using the Vero API or uploaded via CSV. For example, `{{user.first_name}}` would print John for a user profile that has the attribute first\_name with value John.

## Vero-specific merge tags

There are several reserved, Vero-specific fields that enable key Vero Newsletters functions including one-click unsubscribe and "View in browser" (permalink). The following is a list of all available fields:

* `{{url.unsubscribe_link}}` inserts a unique unsubscribe URL (e.g. `https://connect.getvero.com/unsubscribe/UNIQUE_HASH`). When a recipient clicks this link their user record will be marked as unsubscribed.
* `{{url.unsubscribe}}` inserts an anchor tag containing the raw unsubscribe URL generated by `{{url.unsubscribe_link}}` (as above).
* `{{url.permalink_link}}` inserts a unique URL (e.g. `https://connect.getvero.com/view-online/UNIQUE_HASH`) that points to an online, hosted version of the individual message that was sent.
* `{{url.permalink}}` inserts an anchor tag containing the raw "View in browser" URL generated by `{{url.permalink_link}}` as noted above.

## Liquid functions

Vero supports most default Liquid functions, as well as a number of additional functions for convenience.
