README excerpt
# Forge — Email Marketing for the Rest of Us > **Hackathon Problem Statement #1: Build a Tool That Should Exist** > Create the AI-native app or workflow you wish someone had already built. Eliminate busywork. Make hard things effortless. Built in 4 days for the [Built with Opus 4.6: a Claude Code Hackathon](https://cv.inc/e/claude-code-hackathon) (Feb 11–16, 2026). --- ## The Problem Small businesses know email marketing works. But the tools available to them are either enterprise-grade labyrinths (HubSpot, Mailchimp's 47 menu items) or bare-bones APIs that require a developer. There's a gap: a platform that guides non-technical users through proven email strategies with AI doing the heavy lifting on content — so they go from signup to sending in minutes, not days. ## What Forge Does **Forge** is a full marketing automation platform that combines guided email flows, a visual drag-and-drop email builder, and AI-powered content generation to make email marketing effortless. The demo narrative tells the story: > Small business signs up. Creates a flow from a template — "Welcome Series", "Monthly Newsletter", "Win-back Campaign". AI helps write the subject lines and body copy. They're sending emails in minutes. --- ## Features ### Visual Email Builder Drag-and-drop block editor with 11 block types: heading, text, button, image, divider, spacer, social links, columns, blockquote, video, and raw HTML. Split-pane view with live preview rendered through React Email. Full
