# Using Conditions in Email Signatures

Want to make your email signatures smarter? With Spreadly, you can use *conditions* to show or hide specific content—like legal disclaimers—based on the email context. This is super useful if, for example, you want to display a disclaimer only for external recipients, but keep things clean for internal emails.

In this article, we'll walk you through:
* How conditions work in Spreadly signatures
* Which conditions are available
* Real-world example for legal disclaimers
* A quick reference for all condition types

## What Are Conditions?

Conditions let you control what parts of your email signature are shown, depending on things like:
* If the recipient is external
* Whether the email is a reply or forwarded message
* Other variables you define

You use Liquid syntax (`{% if ... %}`, `{% unless ... %}`, etc.) to write these conditions directly in your signature template.

## Example: Legal Disclaimer Only for External Emails

Let's say you want to add a legal disclaimer at the bottom of your signature, but *only* if the recipient is external.

Here's how your signature template could look:

Notice this part at the end:
```liquid
{% if email.is_external %}
This email and any attachments are confidential and intended solely for the use of the individual or entity to whom they are addressed...
{% endif %}
```

## Available Condition Types
Spreadly supports several condition types, so you can get super specific with your rules. Here’s a quick overview of the main ones, along with examples:

### 1. if
Executes a block of code only if a certain condition is true.
```
{% if product.title == "Awesome Shoes" %}
  These shoes are awesome!
{% endif %}
```

### 2. unless
The opposite of if—executes a block of code only if a certain condition is **not** met.
```
{% unless product.title == "Awesome Shoes" %}
  These shoes are not awesome.
{% endunless %}
```

This is the same as:
```
{% if product.title != "Awesome Shoes" %}
  These shoes are not awesome.
{% endif %}
```

### 3. elsif / else
Add more conditions within an if or unless block.
```
{% if customer.name == "kevin" %}
  Hey Kevin!
{% elsif customer.name == "anonymous" %}
  Hey Anonymous!
{% else %}
  Hi Stranger!
{% endif %}
```

### 4. case/when
Creates a switch statement to execute a particular block of code when a variable has a specified value.
```
{% assign handle = "cake" %}
{% case handle %}
  {% when "cake" %}
    This is a cake
  {% when "cookie", "biscuit" %}
    This is a cookie
  {% else %}
    This is not a cake nor a cookie
{% endcase %}
```

## Pro Tips
* You can use variables like email.is_external, email.is_forwarded, and email.is_reply in your conditions.
* Combine multiple conditions for even more control.
* Use these features to ensure you’re only showing the right content to the right people, keeping your signature tidy and compliant!
* You can check the existence of a placeholder by `{% if user.phone %}`
