About MailJunky
## About MailJunky MailJunky is an AI-native email platform built for two audiences at once: developers who need a reliable transactional Email API and SMTP gateway, and marketers who want to run sophisticated campaigns without writing HTML or wiring up an automation builder. Describe what you want in plain English — "send a cart reminder 30 minutes after abandonment with a 10% discount" — and MailJunky's AI assembles the trigger, conditions, email copy, and tracking for you. Under the AI layer sits a fast, standards-friendly delivery stack: a Node.js SDK (`@mailjunky/sdk` on npm), REST API, SMTP gateway, domain verification, webhooks, event tracking, and real-time analytics. You get the deliverability and control developers expect from a modern provider like Resend or Postmark, paired with the workflow and template tooling usually locked inside heavyweight suites like Klaviyo or Mailchimp — at a fraction of the price. ## Product Insights - **AI Workflow Builder.** Describe automations in plain English and the AI builds the full flow: triggers, delays, branching conditions, emails, and measurement. No drag-and-drop canvas, no YAML, no Zapier glue. - **Email API & SMTP Gateway.** Developer-first transactional sending with a typed Node.js SDK, a clean REST API, and drop-in SMTP for legacy stacks. Ship your first email in under five minutes. - **Event Tracking & Analytics.** Track any user action as an event. Use events to trigger automations, segment audiences, and attribute revenue. Opens, clicks, bounces, and conversions in real time. - **Email Templates.** Responsive templates marketers can customise visually and developers can drive via API. A Template Marketplace with revenue share for designers is launching Q1 2026. - **Audience Health Monitoring.** Continuous visibility into deliverability, domain reputation, bounce rates, and engagement scores — so sender reputation never quietly decays. - **AI Assistant.** Built-in assistant for drafting copy, rewriting subje
