Best MJML Editor in 2026: A Practical Comparison
Searching for the best MJML editor
MJML has become the default way to produce responsive, cross-client email HTML without hand-coding nested tables. (If you’re new to the format, our What is MJML? guide explains what it is and why it exists.) Once you’ve decided to build on MJML, the next question is which editor to author in — and most “best MJML editor” roundups either rank tools that don’t actually produce MJML, or rank tools that do without explaining where each one fits.
This comparison narrows the field to editors that genuinely produce or compile MJML, and looks at them through the lens that actually matters: how you author (code or visual), what the compiled output looks like, how it renders across email clients, and what happens when more than one person needs to work on the same email.
We looked at five editors that get recommended for MJML work. Here’s the framework we used, what each one does well, and where they diverge.
How we evaluated them
Five criteria decide whether an MJML editor is the right pick, not just a flashy demo:
- Authoring style — do you write MJML markup directly, design visually, or both? Each suits a different reader.
- Quality of the compiled output — clean, readable, and aligned with MJML conventions, or bloated and hard to debug?
- Cross-client rendering — does the output land correctly in Gmail, Outlook, and Apple Mail without a separate testing step? (See why HTML emails use tables for why this is hard.)
- Collaboration — can more than one person work in the same editor, with roles, version history, and isolated brand spaces?
- Export and ESP handoff — does the editor produce portable HTML, and can it push directly to your sending tool?
Here’s how the five compare:
| Editor | Authoring style | Output | Collaboration | Pricing model | Best for |
|---|---|---|---|---|---|
| MJML Online Editor | Code (raw MJML) | MJML-compiled HTML | None | Free | Developers learning or testing MJML |
| Stripo | Visual + code | Visual builder with MJML import/export | Per seat | Per seat | Designers who want a large template library |
| BEE Pro | Visual | Visual builder with MJML export | Per seat | Per seat | Solo designers who want a familiar drag-and-drop |
| Mailjet Email Editor | Visual | Native MJML builder (Mailjet maintains MJML) | Per account | Bundled with sending | Teams already sending through Mailjet |
| Temway | Visual + AI | Compiles designs through an MJML engine | Per workspace, not per seat | Per workspace, not per seat | Teams that want MJML-quality output without writing markup |
The rest of this comparison explains where each editor earns its place, and — just as importantly — where each one falls short.
Best for raw MJML: the official MJML Online Editor
The MJML Online Editor is the reference implementation — maintained by the same team that maintains MJML itself. You write raw MJML in a browser-based code pane, see a live preview, and copy the compiled HTML out. It’s free, requires no account, and is the fastest way to try a snippet of MJML or learn how the format works.
Where it tends to fall short: there’s no visual canvas, no collaboration, no asset library, and no ESP handoff. It’s a code editor with a preview pane, full stop. If you want to design emails visually rather than write markup, this isn’t the tool. For everyone else, it’s a genuine starting point and the canonical place to verify that a piece of MJML renders the way the format intends.
Best for template volume: Stripo
Stripo gets mentioned in every MJML editor roundup for good reason: its visual canvas can import and export MJML, the template library is one of the largest in the category, and the dual visual-plus-code view lets technical senders drop into the markup when they need to. AMP for Email support, built-in testing integrations, and project-level brand settings round out a genuinely capable tool. Read the deeper Stripo alternative comparison for the full picture.
Where teams tend to outgrow it: pricing scales per seat, so adding contributors moves the bill noticeably. The interface is dense enough that new editors need a runway. And while Stripo handles MJML import and export well, the visual builder is not itself a pure MJML authoring surface — it’s a general-purpose email builder that speaks MJML as one of several formats.
Best for a familiar drag-and-drop: BEE Pro
BEE Pro is a visual builder with a clean, recognizable drag-and-drop interface and MJML export. If you’ve used BEE anywhere else (its embeddable editor appears in a number of products), the workflow will feel familiar immediately. Brand kits, a decent template library, and HTML export round out a capable solo-designer tool.
Where it falls short for teams: per-seat pricing, limited version history, and collaboration organized at the organization level rather than around isolated workspaces. If your team has hit those limits, see how a workspace-first builder compares in our best email builder for teams roundup.
Best if you already send through Mailjet: the Mailjet Email Editor
Mailjet created MJML and maintains it as an open-source project, so it’s no surprise their email editor builds on it natively. If you already send through Mailjet, the bundled editor is effectively free in the sense that you’re not adding another tool, and the MJML foundation means the output is solid.
Where it falls short for design teams: the editor is a feature of the sending platform, not the product. Collaboration is limited (shared accounts, basic roles), version history is shallow, and branding tends to be per-account rather than per-brand. Teams usually outgrow the bundled editor when a second designer joins or when they start managing multiple brands.
Best for teams that want MJML-quality output without writing markup: Temway
Temway is a visual, drag-and-drop email builder that renders every design through an MJML engine. You compose with blocks — text, images, buttons, social links, multi-section layouts — and Temway compiles the design into the same battle-tested HTML MJML produces. The rendering problems MJML solves (responsive layouts, Outlook workarounds, mobile stacking — see how CSS inlining works in email for one of the harder pieces) are handled for you, and you never write or see a line of markup unless you choose to export the raw HTML.
What this means in practice:
- You design visually. Drag blocks, set colors and fonts once per workspace, and every email starts on-brand.
- AI authoring is part of the workflow. Describe an email in plain language — “a welcome email for a SaaS trial signup, friendly tone, blue accent” — and get a structured, branded first draft, then refine by conversation before finishing by hand.
- You export real HTML. The export pipeline produces clean, self-contained HTML ready to paste into any ESP or sending tool. Nothing locks you in.
- Sending stays where it belongs. Temway is a builder and exporter. You design and export, then push the finished email to Mailchimp, Klaviyo, HubSpot, SendGrid, Brevo, or ActiveCampaign, where it lands as an editable template. Your lists, automation, and deliverability stay exactly where they already work.
- One design, two outputs. Every Temway email exports as real HTML and a matching web page — so a newsletter ships as both an inbox-ready email and a landing-style page without being rebuilt.
Where Temway is not the right pick. Honest concessions matter in a comparison:
- You want to write MJML by hand. Temway’s authoring surface is visual and conversational, not a code editor. If writing MJML markup is the workflow you want, the official MJML Online Editor is the better fit.
- You need AMP for Email. If interactive emails are central to your strategy, Stripo’s AMP tooling is more developed.
- You want the largest possible template library. Stripo and Mailchimp ship with larger pre-built libraries. Temway’s templates gallery is growing but smaller — though each entry is a real, production-grade email you can adapt, like the Welcome aboard SaaS template.
For teams that want MJML-quality rendering without authoring in markup, Temway is the strongest fit.
Pricing comparison
| Editor | Cheapest paid plan | Pricing model | Free tier |
|---|---|---|---|
| MJML Online Editor | None — fully free | Free, no account | Yes — full editor, no limits |
| Stripo | Starter | Per seat | Yes, limited |
| BEE Pro | Team | Per seat | Yes, limited |
| Mailjet Email Editor | Standard | Bundled with sending | Free, with sending limits |
| Temway | Starter ($19/mo) | Per workspace, not per seat | Yes — 1 workspace, full builder, custom fonts |
The key distinction: Temway prices per workspace, not per seat. Adding a teammate doesn’t move the bill. Most other visual MJML editors on this list price per seat, so a fifth editor costs the same again as a fourth. For a growing team, that’s the line item that decides whether collaboration is affordable. Paid plans scale from Starter at $19/mo through Pro at $49/mo up to Max at $299/mo — see Temway’s pricing and billing and plans for the full breakdown.
How to pick
Five questions narrow this down fast:
- Do you want to write MJML markup, or design visually? Write markup → MJML Online Editor. Design visually → Stripo, BEE Pro, Mailjet, or Temway.
- How many people will edit emails at once? One or two → any tool works. Three or more, or multiple brands → Temway.
- Are you already sending through an ESP with a bundled builder? Already on Mailjet → its bundled editor may suffice. Otherwise pair Temway (or another standalone builder) with your ESP.
- Is AI authoring a real workflow win? Yes → Temway. Nice-to-have → any tool with AI features.
- Does pricing scale per seat or per workspace? Per-seat tools get expensive fast as the team grows; Temway’s per-workspace model doesn’t.
Most teams evaluating “best MJML editor” seriously land on Temway or Stripo. Stripo wins for designers who lean on a large template library and AMP. Temway wins for teams that want MJML-quality output, AI authoring, version history, and per-workspace pricing in one place.
Frequently asked questions
What is the best MJML editor?
It depends on how you author. For writing raw MJML markup, the official MJML Online Editor is the canonical choice. For visual design that compiles to MJML-quality HTML, Temway is the best fit for teams (per-workspace pricing, AI authoring, version history), while Stripo is the strongest pick for designers who lean on a large template library.
Is there a free MJML editor?
Yes. The MJML Online Editor is free with no account. For visual building, Temway’s Free plan includes a full workspace with the complete builder and custom fonts, with no credit card required. The main limit is volume (emails, exports, team members). See billing and plans for the full breakdown.
Can I use MJML without writing code?
Yes. Temway is a visual, drag-and-drop builder that renders through an MJML engine, so you compose emails by arranging blocks and the compilation is handled for you. You never write or see MJML markup unless you choose to export the raw HTML. Stripo and BEE Pro also offer visual building with MJML import and export.
Does MJML output work with Outlook?
Yes. MJML’s compiled output includes the Outlook-specific fixes the Word-based rendering engine requires — button backgrounds, spacing, alignment, and rounded corners all include the necessary fallbacks automatically. Every visual editor listed here produces output that respects those fallbacks.
Can I push MJML-compiled emails to my ESP?
Yes. Temway pushes finished emails straight into Mailchimp, Klaviyo, HubSpot, SendGrid, Brevo, and ActiveCampaign as editable templates — you design in Temway, send from your ESP. Stripo supports a wide range of ESPs and CRMs. The MJML Online Editor produces portable HTML you can paste into any ESP’s template builder.
