Definition
Classic Email Templates is a Setup page for creating and managing email templates in the Salesforce Classic format, including text, HTML with letterhead, custom HTML, and Visualforce templates. While Lightning Email Templates are the newer standard, Classic templates remain available for workflows, approval processes, and legacy integrations.
Real-World Example
The admin at Cobalt Dynamics maintains a set of Classic Email Templates used by workflow rules and approval processes. She opens the Classic Email Templates page to update the "Case Escalation Notification" HTML template with a new company logo and updated support contact information. Since this template is referenced by an active workflow rule, she uses the Classic format for compatibility.
Why Classic Email Templates Matters
Classic Email Templates serve as a foundational way to standardize and automate email communication within Salesforce orgs that have legacy processes tied to workflows, approval processes, and integration touchpoints. Unlike Lightning Email Templates which offer modern UI enhancements and wider compatibility, Classic Email Templates are specifically designed to maintain backward compatibility with existing automation rules that may have been configured years ago. Many organizations cannot simply migrate all their email templates to Lightning because doing so would break active workflow rules, approval routing, or third-party integrations that explicitly reference Classic template IDs. This makes Classic Email Templates essential infrastructure for mature orgs where stability and continuity are critical—you cannot delete or significantly alter a Classic template without first identifying and updating every automation that depends on it.
As orgs scale and accumulate hundreds of configured workflows and approval processes, Classic Email Templates become increasingly difficult to govern without proper documentation and version control. When template owners retire, leave the organization, or forget which templates are actively used, teams risk accidentally breaking critical business communications—imagine a customer onboarding workflow suddenly failing to send welcome emails because someone deleted what they thought was an unused template. The real-world consequence is that many orgs become 'trapped' by their Classic Email Templates; they cannot fully modernize their email strategy because untangling the dependency web is too risky. Best-practice organizations prevent this by maintaining a comprehensive audit of which templates are referenced by which automation rules, regularly documenting template purposes, and planning migration paths to Lightning Email Templates incrementally rather than all at once.
How Organizations Use Classic Email Templates
- Pinnacle Financial Services — Pinnacle maintains a suite of Classic Email Templates for loan approval workflows and customer notification processes that have been in production for 8+ years. When they attempted to migrate to Lightning Email Templates, they discovered 23 workflow rules, 7 approval processes, and 3 legacy integrations still pointing directly to Classic template IDs. Rather than risk breaking mission-critical loan communication, they decided to keep their Classic Email Templates in place for these high-stakes processes while gradually building new notification workflows using Lightning Email Templates. This dual-template approach gave them stability for proven processes while allowing innovation for new features.
- Vertex Manufacturing — Vertex uses Classic Email Templates for order confirmation, shipment notification, and return authorization emails triggered by workflow rules that operate on custom Order objects. Their manufacturing team updates these templates quarterly to reflect seasonal messaging, regional compliance notices, and partner branding guidelines. By using the <strong>HTML with Letterhead</strong> template type, Vertex maintains visual consistency with their corporate branding while keeping the template logic simple and maintainable. This approach reduced email design inconsistencies by 85% and cut template update time by 40% compared to their previous manual email approach.
- Cascade Health Solutions — Cascade uses a <strong>Custom HTML</strong> Classic Email Template for multi-language patient communication triggered by approval processes for treatment authorizations. Since their patients are distributed across four countries with different languages and regulatory requirements, they built a single template using conditional Salesforce merge fields to dynamically populate content in English, Spanish, French, or German. Although Lightning Email Templates are available, the team determined that their heavily customized merge field logic was simpler to maintain in Classic HTML format, and the template's integration with their approval process chain meant migrating would require extensive testing. This custom approach has processed over 50,000 patient communications with a 99.2% delivery success rate.
