Custom Fonts

Fonts are an important part of a brand’s identity – they help keep all your email designs consistent and recognizable.

In Postcards, you can upload and use custom fonts to make your templates look unique and on-brand.

Note: Custom fonts are available only in Plus and Pro plans.

Important: If you cancel a paid plan, custom fonts remain available during a 14-day grace period. If the plan is not reactivated, custom fonts, along with hosted images, CDN assets, and Preview links, are permanently deleted after 14 days.

Variable Fonts Support

In Postcards, each uploaded font file is treated as a single, independent style.

This means that even if you upload a variable font file (.ttf VF) that technically contains multiple weights within one file, the editor may not recognize or group those weights under a single unified font family.

For best results and full control inside the editor, we recommend exporting individual static font files per weight/style and uploading them separately.

Ways to Add Custom Fonts

There are two ways to add custom fonts in Postcards:

From a Text Layer

Select any text layer in your project.

In the right sidebar, next to the Text title, you’ll notice a menu icon (three lines).

Click it → choose Custom Fonts.

A Custom Fonts popup will appear, giving you two upload options:

(a) Click the blue “click here to browse” link to open your file picker and select fonts manually

(b) Drag and drop a single font file or multiple files directly from your device

From the Default Font Family

Click anywhere on the canvas background (to deselect all layers).

In the right sidebar (Container) find Default Font Family.
Next to it, click the menu icon.
Select Custom Fonts → the same upload popup will appear.

Once you’ve uploaded fonts (one or more), you’ll see a list of all of them with several options and fields:

Font File Name - Displays the uploaded file’s original name.
Bin Icon - Deletes that specific font, useful if you uploaded a batch and want to remove some.
Font Family - A name field, you can keep the default or set your own recognizable name.
Font Weight - Usually detected automatically, but you can change it using the dropdown (e.g. Regular, Bold, 600, etc.).
Style - Choose between Normal and Italic. This setting follows standard HTML behavior — any font can technically be displayed as italic even if the uploaded file isn’t a true italic version. However, for branding accuracy and visual quality, it’s best to use genuine italic font files when possible.

Once all details are correct, press the green “Add Font” button to confirm.

Note: Without pressing Add Font, your upload won’t be saved.

Applying a Custom Font

Once your font is uploaded and confirmed:

Select the text you want to update.
In the right sidebar, under the text section, click on the current font name.
Your uploaded font(s) will now appear in the list below.
Click on your custom font – the text will instantly update to use it.

Edit or Delete Uploaded Fonts

You can edit or delete your uploaded fonts using the same Custom Fonts popup.

Under each font name, you’ll see two icons:

Edit (rectangle with a diagonal line)
Delete (bin icon)

Edit

Click the Edit icon to modify:

Font Family Name
Font Weight
Style (Normal or Italic)

Don’t forget to press the green “Update” button to save changes.

To cancel edits, press the X (close) icon.

Delete

Click the Bin icon.

A confirmation prompt will appear: “No, cancel” or “Yes, delete.”

Confirming will permanently remove the font – this action cannot be undone.

Important: Fonts currently in use in any project cannot be deleted. You’ll first need to replace them with another font before removal.

When a Custom Font Isn't Supported

Uploading a custom font doesn't guarantee every recipient sees it. Plenty of email clients — Outlook on Windows most of all — might not load web fonts at all. When that happens the client substitutes something else, and unless you've told it what to use, it chooses for you.

The Fallback Font setting makes that choice yours. Click an empty area of the canvas to deselect all layers; in the right sidebar Container panel, Fallback Font sits below Default Font Family.

Alongside the 16 built-in options you can enter your own font stack: open the dropdown and type a comma-separated list such as Calibri, Arial, sans-serif into Add custom fallback. The client works through the list in order and uses the first font installed on the recipient's device, so put your closest match first and end with a generic family (sans-serif , serif , or monospace ).

Tip: Choose a fallback with proportions close to your uploaded font. A condensed display font that falls back to a wide default will reflow your headings and can pull a carefully spaced layout apart.

Custom fallback sets save to your workspace and appear in every project in it. For the full details, see How Text Works in Postcards.
