Visual email builder
Build emails that look right in every inbox.
Drag and drop blocks. Compile to MJML. Survive Outlook, Gmail dark mode, and the phone in your client's pocket — without touching a single <table> tag.
Included in every plan. No credit card to try it.
Built for every inbox
Your design survives dark mode.
Same email, same blue header — once on a light client, once in Outlook with dark mode forcing inversions. Look closely: the hero block is the color you picked, in both.
- Outlook inverts CSS colors.background-color values get flipped to fight light themes — your blue becomes a different blue, or worse.
- It leaves image bytes alone.A tiled 1×1 PNG of the same color renders untouched, so your design lands intact.
- 18 presets, drop-in.Pick a brand-friendly color from the panel — the builder swaps in the image-tile technique automatically.
Drag and drop
Every block you actually need.
Pull a block onto the canvas, tweak it inline, save it for next time. No nesting tables, no fighting Outlook quirks, no copy-pasting from old campaigns.

How it gets to the inbox
Three steps you don't have to think about.
You design. The pipeline does the rest — quietly compiling, normalising, and shipping email-safe HTML that survives Outlook, Gmail, Apple Mail, Yahoo, and every mobile client your audience opens it in.
Step 1
1. Design
Drag, drop, customize. No HTML.
Step 2
2. Compile to MJML
MJML output handles the cross-client weirdness for you.
Step 3
3. Render everywhere
Outlook, Gmail, Apple Mail, Yahoo, mobile clients — pixel-correct.
Less staring at a blank subject line.
AI assist on subject lines, body copy, and a pre-send spam-score check. Every plan includes a monthly credit allowance.
Subject composer
Bring tone, length, and audience hints. Get 3–10 ranked options you can A/B test in one click.
Body composer
Start from a brief, expand a paragraph, rewrite with a different tone, or repurpose a winning campaign.
Spam-score & pre-send
Catches risky words, broken links, missing unsubscribe, and tracking-domain gaps before you hit send.
MJML, dark mode, and what the builder does for you.
The five questions designers and devs ask before they put the builder in front of a client.
MJML is a markup language designed for email — it compiles down to the table-soup HTML that Outlook and old clients still need, but you never have to look at that output. The builder writes MJML, MJML compiles to email-safe HTML, and your design renders correctly across every major desktop, web, and mobile email client your audience opens it in.
Yes. Outlook Windows, Gmail Android, and Apple Mail iOS will invert CSS background-color values to fight light themes — which mangles designs. Our 18 background-color presets ship as 1×1 PNG images tiled across the block. Those clients leave image bytes alone, so the color stays the color you picked. Pick a preset, stop fighting the inbox.
You can paste MJML and our compiler will round-trip it. Raw HTML is harder — email HTML is fragile and most hand-written templates break in at least one client — so for HTML the builder is best used as a from-scratch authoring tool, not an importer.
Yes. Every workspace gets its own S3-backed media library — uploads, folders, and search are isolated per client workspace. Nothing bleeds between accounts.
More than you’d think. Inboxes that block HTML, Apple Watch previews, and most spam filters look at the plain-text part. We auto-generate it from your visual layout so deliverability stays clean and accessibility users get a readable version.
Yes. Any block — header, footer, signature, CTA card — can be saved to the workspace’s block library and dropped into any campaign or automation email. Edit once, propagate everywhere optionally.
