Email marketing that runs itself.
Generate on-brand campaigns in seconds, deploy autonomous AI agents, and scale your entire email program — from your audience to your analytics — in one premium platform.
"Create a Black Friday abandoned-cart sequence for our new sneakers, targeting high-value customers using last month's data."
One platform
Everything your email program needs
Replace your generator, your ESP, and your analytics stack with one AI-native system.
Brand Intelligence Hub
Upload assets or sync your website. AI learns your voice, colors, and guidelines to keep every email perfectly on-brand.
Autonomous AI Agents
Deploy pre-built agents — Campaign Planner, Optimizer, Deliverability Guardian — or build your own with approval gates.
Visual Automations
Drag-and-drop journeys for welcome series, abandoned cart, post-purchase, and win-back. AI suggests timing and steps.
Audience & CRM Lite
Behavioral segmentation, custom fields, and AI personalization with dynamic content blocks. Import and export in clicks.
Analytics & AI Coach
Opens, clicks, and revenue with UTM tracking. Your AI Coach explains what's working and rewrites what isn't.
Deliverability Suite
Sender reputation tools, warm-up simulation, spam-score checks, and multi-domain support to land in the inbox.
The killer feature
The AI Email Studio
Describe what you want in plain language. MasterEmail writes the subject lines, designs the responsive HTML, and renders it perfectly for every inbox — ready to edit inline or in code view.
- Subject lines with predicted open rates
- Beautiful, responsive, on-brand HTML
- Inline editing + full code view
- Gmail, Outlook & mobile render previews
- One-click A/B variant generation
Limited drop
Your cart misses you 👟
Agent marketplace
Hire AI that does the work
Pick from pre-built agents or describe your own: "Build an agent that plans, creates, tests, and sends a newsletter every Monday." You keep the approval gates.
Campaign Planner
Plans your monthly calendar around launches, holidays, and audience behavior.
Optimizer
Continuously tests subject lines, send times, and content to lift conversions.
Deliverability Guardian
Monitors reputation, warms domains, and flags spam risk before you send.
