It is possible use this operator with dynamic fields 'as is' only to compare strings.

Code Block

In this case the check is case sensitive.

To compare numbers or data type different from string it is possible use the built in functions:

Introduction

The liquid is an open-source template language created by Shopify and written in Ruby. It is the backbone of Shopify themes and is used to load dynamic content on storefronts.

In MailUp Liquid is used as a markup language for the email messages that use Advanced content personalization.

The following guide describes how to use Liquid within MailUp and which statements are supported.

When talking about dynamics fields, we refer to the MailUp Recipient fields.

To retrieve a specific dynamic field value, you have to use the following syntax: dynamicfields.<dynamic field name>.

Note

In the liquid syntax, not all characters are supported in a variable name. To be sure to have a correct syntax when using MailUp dynamic field, we recommend using only:

digits (0...9)
letters (a...z and A...Z)
dash (-) and underscore (_) signs

For MailUp Recipient fields that contain these characters:

accented characters should be substituted with normalized characters (e.g. 'CrèmeBrûlée' -> 'CremeBrulee')
special characters, such as full stop (.), space (' '), dollar('$'), should be removed from the field name (e.g. 'Is a colleague' -> 'Isacolleague').
