Introduction to Snippets

Snippets are reusable content blocks that you can add to your templates to make building and personalizing messages in Iterable even easier. With snippets, you can:

• Manage frequently used elements like email headers and footers
• Store complex logic blocks
• Update multiple templates at the same time

# Required permissions

To create, edit, or delete a snippet, you'll need the Snippets > Create & Manage permission.

# What's in a snippet?

To work with snippets, there are a few terms you'll need to know.

# Name

Give each of your snippets a helpful and descriptive name, because you'll use these names to reference them in your templates. Snippet names can include letters, numbers, spaces, dashes, and underscores.

To help make it easier for your team to organize and collaborate on your snippets, it can be helpful to use a consistent naming convention.

Snippet names are internal to your organization (your users won't ever see them).

# Snippet content

This is the content that will be inserted in any template that references the snippet. For example, a snippet's content might include a banner, a list of product recommendations, or a message footer.

Snippets can include:

• HTML (including images)

  To use an image in a snippet, you'll need to reference one that's already hosted somewhere. Be sure to close your HTML tags, and remember that some mediums (like SMS) can't render HTML.

• CSS

  Snippets support inline CSS on HTML tags (using the HTML style attribute). However, <style> tags are not supported.

  Standard precedence rules apply to CSS contained in a snippet:

  • A more-specific selector takes precedence over a less-specific one.
  • If two CSS rules have the same specificity, the one that appears later in the code takes precedence.
  • A CSS rule with !important always takes precedence.

• Handlebars

  To reference a user profile field, event field, or variable, use a Handlebars expression. For example, {{location}} or {{#if signedUp}}. To learn more, read Personalizing Templates with Handlebars

• Data feeds

  A snippet can reference data feeds. However, you'll need to make sure that any templates that reference the snippet are properly configured to use data feeds.

Snippets cannot include:

• <script> tags
• <iframe> tags
• JavaScript
• References to themselves

# Variables

Variables (previously called Positional Parameters) are dynamic fields included in a snippet's definition, so that individual templates can customize them as needed.

When a template references a snippet, it should provide values for all of that snippet's variables. Then, the snippet's content can use the passed-in values however it needs (displaying them, using them for conditional logic, using them to modify styles, etc.)

For example, a snippet might define variables that require templates to pass in a CTA, a color, or a value that it can use to help decide what content to display (using conditional logic in Handlebars).

To learn more, read Customizing Snippets with Variables.

# Snippet expression

This is the Handlebars code that Iterable generates for you when you create a snippet, and it's what you'll use to include the snippet in a template.

Think of a snippet expression like a shortcut. Instead of including a given chunk of content directly in every template that needs it, you can put that content in a snippet and use the snippet expression to include it wherever it's needed.

# Creating snippets

The Snippets page is a central repository for all of the reusable content blocks in your Iterable project:

To create a new snippet:

1. Navigate to Content > Snippets and click New snippet.

2. Give your snippet a name. You won't be able to change this later, so make sure you choose a unique, descriptive name (don't use test123).

3. (Optional) Add variables, so that template can customize the snippet as needed.

4. (Optional) Add a description to help your teammates understand what this snippet is for.

5. Add your snippet's content, in the Editor section.

   NOTE

   You can create snippets using either the WYSIWYG or Side-by-Side editor. To switch between these two options, use project settings.

6. Click Save snippet.

To learn more about creating snippets, see Tutorial: Create Your First Snippet.

# Editing snippets

To modify a snippet, it's best to save it as a copy, test it, and then update the original after you've confirmed that your changes are working as expected.

To save a snippet as a copy:

1. Navigate to Content > Snippets.

2. Open the original snippet and make any necessary changes.

3. Click Save snippet.

4. In the Save Snippet menu that opens, click Save as new.

   

5. Give your new snippet a name. Then, click Save snippet.

6. Test the new snippet by adding it to a template, previewing it with data, and sending proofs.

7. If everything looks good, copy the updated content over to the original snippet. This is a global change, and it will update all templates and campaigns that reference that snippet.
