Blocks

Blocks is an AI project builder tool that designs responsive emails once, export anywhere, no code. Blocks is a no code drag and drop email builder that produces responsive HTML, with 395 templates, an in editor AI assistant for copy and images, and one click export to 59 platforms including Mailchimp, Klaviyo and HubSpot.

Blocks is a no code email builder focused on producing markup that survives real inboxes, Outlook included. The core workflow is block based: instead of opening a blank canvas and hand placing elements, you add, configure and reorder saved parts of an email (product blocks, feature rows, newsletter sections) and the layout assembles itself. A live editor sits on the homepage, so the product can be tested before any account exists. The pitch is aimed at teams who are tired of layouts that break once they leave the builder. The tool serves two distinct audiences. Marketers can start from one of 395 ready made templates covering welcome messages, abandoned carts, order confirmations and seasonal promotions, then edit copy directly in the preview without waiting on a developer. Platforms that already send email, such as CRMs, marketing suites or shop admins, can embed the editor through a plugin rather than building one from scratch. A Figma plugin covers teams that design in Figma first: it generates the email and opens it in Blocks with one click. The AI assistant is scoped tightly to the writing and asset work inside the editor: sharpening a subject line, rewriting a paragraph, generating an illustration. Existing HTML, whether from another builder, a developer or a language model, can be loaded and converted into editable blocks. Images can be hosted on Blocks storage or linked to your own, and version history keeps every state so an earlier draft can be restored rather than rebuilt. Preview and share features cover checking the result at different screen sizes and sending a link to colleagues for review. Export is the strongest differentiator. Most popular platforms are integrated directly, so a template moves from the editor into an account with one button and no export file. Everything else takes an HTML, ZIP, PDF or Outlook export, with 59 platforms listed. The free starting tier requires no card. Among email builders, Blocks sits closer to specialised design tools than to all in one campaign platforms: it handles the design and handoff layer well, but sending, list management and automation remain the job of whatever platform receives the export.
