Unlayer is a San Francisco company that builds an embeddable, API-first content editor. Its core product isn't a marketing app you send campaigns from — it's the drag-and-drop builder itself, packaged so other software companies can drop it inside their own product. A SaaS platform, CRM, or ESP integrates Unlayer's SDK and its users get a fully white-labeled email, page, popup, or document designer that looks native to the host app, with a few lines of code instead of a year of in-house editor work. Its customer list is other software brands, including names like Mastercard, Twilio, and Chargebee.
There are four builders under one editor: email, landing page, popup, and — more recently — documents. The email builder produces responsive HTML that Unlayer says renders reliably across Gmail, Outlook, Apple Mail, and 90+ clients, with over a thousand starter templates, merge tags, an image editor, and localization. The document builder turns the same drag-and-drop canvas into dynamic PDFs and files, exporting to PDF, Word, HTML, and PNG, with merge fields, forms, and e-signature support for things like contracts, proposals, invoices, and offer letters. A built-in AI Assistant can draft a design from a one-line brief and edit it by chat ("shorten this paragraph", "translate this row to Spanish").
Unlayer is also known in the developer world for react-email-editor, its open-source React component (thousands of GitHub stars) that wraps the hosted editor — the free tier of the same product. Paid plans run from a Launch tier upward, with white-labeling and the Cloud API gated to paid, and a free plan that already includes the email, page, popup, and document builders. Confirm current tiers, prices, and limits on Unlayer's own pricing page before relying on them — this is a snapshot.
The honest framing: Unlayer is infrastructure for product teams, not a content operation for a brand. It gives your app's users a beautiful canvas to design one asset at a time, by hand. It doesn't write the week's newsletter, generate a video, or publish anything to a social feed. It's the editor, not the engine.
Unlayer answers "how do I let someone design a single email or document inside my app?" — the canvas question. Kompozy answers a different one: "how do I generate a brand's entire content week and get it published across every platform?" — the engine question. They meet at exactly one place, the newsletter, and seeing that seam is the fastest way to understand where each fits. In Unlayer, a person opens the editor and hand-builds one email, block by block. In Kompozy, the Email Newsletter is one of eighteen formats generated from a single source — a podcast, a webinar, a founder talk, an idea — with the copy written to your Persona Brief so it holds your voice and banned words automatically, not typed into a template by hand.
That's the concrete workflow: keep Unlayer as your app's embedded design surface if you're a product team, and let Kompozy be your own brand's content operation. From one input, Kompozy writes the newsletter and the blog, cuts Clipped Shorts, generates Persona Shorts and HeyGen avatar video with a face-locked recurring identity, builds brand-exact Carousel Posts through HyperFrames, and produces Photo Posts, Quote Graphics, and native Text Posts — then reframes each to 9:16, 1:1, and 16:9 and publishes the batch across Instagram, TikTok, YouTube, LinkedIn, Facebook, X, Pinterest, and Threads plus a blog and Mailchimp, with Autopilot and a per-post review pipeline. Unlayer designs the container; Kompozy fills it with generated, on-brand content and ships that content everywhere else too.
Unlayer is an embeddable, white-label drag-and-drop builder for emails, landing pages, popups, and documents. Its customers are mostly other software companies — SaaS platforms, CRMs, and ESPs — that integrate its SDK so their own users can design content natively inside the host app. It also publishes react-email-editor, a popular open-source React component that wraps the same editor.
No. Unlayer is the design surface — it produces responsive HTML emails and exportable documents (PDF, Word, HTML, PNG). Sending, scheduling, and multi-platform publishing happen in whatever app embeds it or in a separate tool. Kompozy, by contrast, both generates the content and publishes it across eight social platforms plus blog and email.
It turns Unlayer's drag-and-drop canvas into dynamic documents — contracts, proposals, quotes, invoices, offer letters, and reports — with merge fields, forms, and e-signature support, exporting to PDF, Word, HTML, and PNG. It's aimed at product teams that want document creation inside their own SaaS or CRM.
Unlayer has a free plan that includes the email, page, popup, and document builders, and it open-sources react-email-editor. White-labeling and the Cloud API are gated to paid tiers that start at a Launch plan and scale up for higher volume and team features.

Kompozy is a content generation and publishing engine: from one source it writes and renders 18 formats — newsletter, blog, persona/avatar video, carousels, images, text — to a Persona Brief and publishes them across eight social platforms plus blog and email. Unlayer is the canvas; Kompozy is the engine.
