Dyspatch: The Leading Open-Source Library for Free Mobile-Responsive HTML Email Templates

Anyone who has built a responsive HTML email knows the struggle: what renders beautifully in one client can break spectacularly in another. Outlook introduces unexpected gaps, Gmail strips styles, iOS Mail scales unpredictably, and modern CSS support is practically nonexistent. Creating great email templates today still feels like coding websites in the 1990s—and most teams would rather avoid that experience altogether.
Dyspatch Open Source Email Template Project
The Dyspatch Open Source Email Template Project was created to solve this problem. Dyspatch’s mobile-optimized HTML email template library delivers a collection of responsive, multi-client compatible templates that are free, extensible, and maintained collaboratively by both the Dyspatch team and the broader community. These templates are battle-tested, flexible, and—most importantly—open source, giving users complete freedom to use, edit, extend, or repurpose them in any workflow.

Dyspatch’s larger platform amplifies the value of the library. With a no-code visual email builder, streamlined collaboration features, and DML—Dyspatch’s custom markup language—teams can build or customize complex email components with a fraction of the code required by traditional HTML. Thousands of Dyspatch and Sendwithus users have relied on these templates to produce high-quality, client-friendly emails, and the open-source project now enables anyone to tap into that expertise.
The open-source nature of the Dyspatch template library is transformative. Instead of treating templates as locked-down, proprietary assets, Dyspatch invites marketers, designers, and developers to contribute improvements, build new themes, and evolve best practices together. Teams can fork templates on GitHub, import them directly into a Sendwithus dashboard, or customize them in the Dyspatch visual editor. The result is a dynamic, community-guided template ecosystem that improves continuously while remaining freely available.
The diversity of templates ensures that every use case—transactional notifications, onboarding flows, product updates, newsletters, promotions, and more—is covered. Oxygen provides a modern, flexible base ideal for transactional messaging. Mantra, designed in partnership with Email Monks, delivers a minimalist, premium aesthetic. Neopolitan focuses on mobile-first rendering. Additional static HTML templates, such as Goldstar, Cerberus, Go, Sunday, Airmail, Cleave, and Narrative, expand the library with specialized layouts and design options. Each is engineered to perform consistently across the fragmented landscape of email clients.
Dyspatch’s DML language deepens the library’s power by replacing long, error-prone HTML blocks with expressive, reusable components. A structure that might require 130 lines of HTML can be expressed in approximately ten lines of DML—less than ten percent of the usual code footprint. This dramatically speeds up production, improves maintainability, and preserves output quality.
Here are some of the templates available:

Airmail: A clean, modular template tuned for high readability and consistent rendering across major clients.
Cerberus: A trusted, flexible HTML pattern designed for reliability in even the most restrictive environments.
Cleave: A refined template offering a balance of visual interest and minimal setup, adaptable to most brand styles.
Goldstar: A visually polished layout ideal for marketing promotions or brand-forward messaging.
Go: A compact, fast template designed for quick announcements and lightweight transactional communication.
Mantra: A premium minimalist theme developed with Email Monks, well-suited for transactional and marketing emails alike.
Narrative: A layout optimized for long-form content, newsletters, and editorial-style messaging.
Neopolitan: A lightweight, mobile-first template engineered to perform exceptionally well on smartphones.
Oxygen: A modern, adaptable transactional template that aligns with virtually any brand identity.
Responsive Bundles: Complete downloadable packages include HTML files, assets, and documentation for easy implementation.
Sendwithus Integration: Templates can be imported directly into Sendwithus for seamless editing and deployment.
Static HTML Files: Raw HTML versions are provided for developers who prefer full control over customization and deployment.

Every feature reinforces Dyspatch’s core objective: to make professional-grade HTML email accessible without requiring practitioners to become experts in outdated email-client behavior. The open-source nature of the project means improvements are ongoing, and the community directly shapes the library’s evolution.
Getting started is easy. Users can browse the full library of open-source templates, download bundles instantly, customize designs in the Dyspatch visual editor, or integrate them into their email service provider. Developers can clone the GitHub repository, submit enhancements, or create entirely new themes that further strengthen the collection. For teams using Sendwithus, direct template importing simplifies testing and deployment.
The Dyspatch Open Source Email Template Project offers a rare blend of freedom, reliability, and professional-grade design. It removes the most painful aspects of HTML email development while empowering teams to build beautiful communications that work everywhere. For organizations that rely on email—whether for product updates, customer lifecycle messaging, or branded campaigns—Dyspatch delivers an engine of consistency and creativity without the technical burden.
