MJML App: Build Responsive Emails Faster

MJML App vs. Traditional HTML for Email — Which Is Better?

Quick verdict

• Use the MJML App when you want faster, more reliable responsive emails with less hand‑coding (especially for teams or repeatable templates).
• Use traditional HTML when you need absolute control over every markup detail, have very custom layouts, or must avoid a build/transpile step.

MJML App — strengths

• Faster development: semantic mj-components replace nested tables and verbose inline CSS.
• Responsive by default: produces mobile-first, client-tested output (includes Outlook workarounds).
• Live preview & tooling: desktop/online editors, plugins (VS Code, Atom) and offline app with instant HTML output.
• Less maintenance: framework maintainers track client quirks; community components and templates speed iteration.
• Open source & extensible: build custom components or integrate into build pipelines (npm, API).

MJML App — tradeoffs

• Less low-level control: generated HTML can be verbose and harder to hand-edit.
• Build step required: you must transpile MJML to HTML before sending.
• Edge cases: very custom or experimental designs may need manual HTML tweaks for certain clients.
• Dependency: you depend on MJML updates for new client quirks.

Traditional HTML — strengths

• Maximum control: precise markup, CSS and optimization (file size, minimal code).
• No transpilation: edit/send final HTML directly.
• Fine-tuned compatibility: possible to craft client-specific hacks for niche cases.

Traditional HTML — tradeoffs

• Slow and error-prone: manually handling nested tables, inline styles, and client inconsistencies.
• Harder to maintain at scale: repeated patterns and templates increase duplication and risk.
• Steeper testing burden: you must keep up with client rendering changes yourself.

When to choose which (decisive guide)

1. You prioritize speed, consistency, and maintainability: choose MJML App.
2. You need pixel-perfect, one-off, or highly experimental emails with minimal tooling: choose traditional HTML.
3. Team workflows / automation / templates: MJML integrates better into CI/builds and template systems.
4. Tiny email size or extreme optimization constraints: hand-crafted HTML can be smaller and more optimized.

Practical tip

Start templates in MJML to iterate quickly; if a template requires heavy manual hacks, transpile and then hand-edit the generated HTML as a final step.
