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, normalizing, and shipping email-safe HTML to 40+ clients.
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 — from 10 on Hobby up to 2,000 on Business — and Starter signups get 500 one-time credits to play with.
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.
Common questions
Quick answers.
Why MJML instead of raw HTML?+
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 the dozen-plus clients your audience actually uses.
Does it really survive dark mode?+
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.
Can I import an MJML or HTML template I already have?+
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.
Is the media library scoped to my workspace?+
Yes. Every workspace gets its own S3-backed media library — uploads, folders, and search are isolated per client workspace. Nothing bleeds between accounts.
Do plain-text alternates really matter?+
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.
