Classic Letterheads

Classic Letterheads is a Setup page for creating branded letterhead designs that serve as backgrounds for Classic HTML email templates. A letterhead defines the header image, footer content, background color, and border styling that gives emails a consistent, professional appearance aligned with the organization's brand.

A Classic Letterhead defines the visual frame around a Classic HTML email - header logo, footer disclaimer, background colour, border. It exists so that email templates can stay text-focused while a single letterhead change rebrands every template at once. When the company logo changes, you edit one letterhead, and every workflow email starts using the new mark.

The catch is that Classic Letterheads are tied to Classic Email Templates, which are themselves a legacy surface. Most modern email needs (transactional, journey-based, marketing) live elsewhere - in Marketing Cloud, in Lightning templates, or in transactional senders entirely outside Salesforce. The reason letterheads are still worth maintaining is that as long as your org runs workflow Email Alerts or approval-process emails, those messages render through this brand layer. Audit it during any rebrand, and treat the day you delete the last letterhead as a sign you've finally migrated all email out of Classic.
