Editor Settings let you configure the default behavior and appearance of the visual email editor across your team. These settings apply to all templates and control available fonts, color palettes, merge tag groups, font sizes, and test email addresses. To access Editor Settings, go to Emails → Editor Settings in the sidebar. The settings page is organized into three tabs: Appearance, Custom Fonts, and Merge Tags.

​
Appearance Tab

​
Language

Configure the default language for the editor interface. This controls the language of the editor’s UI elements, not the language of your email content. The following 20 languages are supported:

​
Custom Colors

Define a custom color palette that appears in the editor’s color pickers. When team members design templates, they’ll see your brand colors as quick-select options, ensuring consistency across all emails.
  1. Open the Appearance tab
  2. In the Custom Colors section, add hex color values (e.g. #6366F1)
  3. Click Save
Add your primary brand colors, secondary accent colors, and common text colors. This saves time and prevents team members from guessing hex values.

​
Test Email Addresses

Configure a list of email addresses used for sending test emails from the editor. When a team member clicks “Send Test” in the editor, these addresses are pre-populated.
  1. In the Appearance tab, find the Testing Emails section
  2. Add email addresses
  3. Click Save
Add email addresses for different email clients (Gmail, Outlook, Apple Mail) to verify rendering across platforms when sending test emails.

​
Custom Fonts Tab

​
Font Sizes

Configure the available font sizes in the editor’s size picker. This lets you define a consistent type scale for your team. The default font sizes are: 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 20, 22, 24, 26, 48.
  1. In the Custom Fonts tab, find the Font Sizes section
  2. Edit the comma-separated list of pixel values (minimum 1px, maximum 200px)
  3. Click Save
Duplicate values are automatically removed and sizes are sorted in ascending order. Use the Reset to default link to restore the original set.

​
System Default Fonts

The editor includes 15 built-in fonts displayed as a toggleable card grid. You can enable or disable individual fonts to control which ones appear in the editor’s font picker. System fonts cannot be removed. Web-safe fonts (no external loading required):
  • Arial, Georgia, Helvetica, Verdana
Google Fonts (loaded from Google Fonts CDN):
  • Bitter, Cabin, Lato, Merriweather, Open Sans, Oswald, Poppins, PT Sans, PT Serif, Roboto, Ubuntu

​
Adding Custom Fonts

Add custom web fonts through a two-step process:
  1. In the Custom Fonts tab, click Add Custom Font
  2. Step 1 — Enter the font URL (e.g. a Google Fonts CSS URL) and a display label
  3. Step 2 — Select a font family from the list of families detected from your URL
  4. Click Save
After adding a custom font, you can enable or disable it using the checkbox on its card without removing it entirely.
Custom web fonts may not render in all email clients. Most email clients fall back to system fonts. Use custom fonts for decorative text where fallback behavior is acceptable, not for critical content.

​
Merge Tags Tab

Merge tags are dynamic placeholders that get replaced with real data at send time. Editor Settings lets you define merge tag groups that appear in the editor’s merge tag dropdown, making it easy for template designers to insert the right variables.

​
Organizing Merge Tags

Merge tags are organized into groups for easy navigation:
  1. Open the Merge Tags tab
  2. Create groups (e.g., “Customer”, “Order”, “Company”)
  3. Add merge tags to each group with a text (display name), label, and value
  4. Click Save
The merge tag value is auto-generated from the text field — converted to uppercase with spaces replaced by underscores. Values are wrapped in {{ }} brackets in the editor (e.g., text “First Name” becomes value {{ FIRST_NAME }}). Once configured, merge tags appear in the editor’s text formatting toolbar as a dropdown organized by group.
Create merge tag groups that match your data model. For example, a “Customer” group might contain first_name, last_name, and email, while an “Order” group contains order_id, total, and tracking_url.

​
Loop Tags

For merge tags that represent a list of items (e.g., order line items), enable the Is Loop Tag toggle on a merge tag item. This adds support for child properties — nested merge tags that repeat for each item in the list. Each child property has:
  • Text — The display name in the editor
  • Label — A descriptive label
  • Value — The placeholder variable name
  • Type — The content type: text, image, button, or number
For example, an “Order Items” loop tag might have child properties for PRODUCT_NAME (text), PRODUCT_IMAGE (image), QUANTITY (number), and PRICE (text).
