Letterheads are the brand wrappers for Classic HTML Email Templates — header logo, footer disclaimer, branded colors. Apply consistently across email templates for visual brand uniformity. Lightning Email Templates have their own embedded brand styling separately (no Letterhead concept). For Classic, Letterheads remain the standard.
- Open Setup → Classic Letterheads
Setup gear → Quick Find: Classic Letterheads → Classic Letterheads.
- Click New Letterhead
Top-right of the list.
- Set Letterhead Name and Description
Convention: per-brand or per-team ("Acme - Primary").
- Tick Available For Use
Without this, the letterhead doesn't appear in Email Template pickers. Common oversight.
- Configure Header section
Logo image (uploaded as a Document), top color band height, alignment.
- Configure Footer section
Disclaimer text, color, font.
- Configure Background colors and Top / Bottom Borders
Body color, border width and color.
- Save → use in HTML Classic Email Templates
When creating an HTML Classic Email Template, pick this Letterhead from the Letterhead picker.
Required.
Required to be ticked for the Letterhead to appear in template pickers.
- Letterheads only work with HTML Classic Email Templates. Lightning Email Templates have their own embedded styling — Letterheads aren't a thing there.
- Available For Use is off by default. Forgetting to tick this leaves the Letterhead invisible — same gotcha as Classic Email Templates and Quick Text.
- Logo images are stored as Documents (legacy Document object). Document storage counts against file storage limits — large logos add up across many letterheads.
