Sequenzy is an AI-powered email marketing platform built specifically for SaaS founders and product-led teams. It unifies onboarding, trial nurture, dunning, campaigns, and transactional emails in one place, with native integrations for Stripe, Paddle, and Lemon Squeezy. You describe your goal, and its AI Sequence Builder generates production-ready email flows with timing logic, subject lines, and copy in minutes. Ideal for startups managing subscriptions, MRR, and user lifecycle events without the complexity of tools built for e-commerce.

• AI Sequence Builder: Describe your goal in plain English and get a production-ready email sequence with timing, subject lines, and optimized copy in seconds.
• Native Billing Integrations: Direct connections with Stripe, Paddle, and Lemon Squeezy automatically trigger emails based on payment events, trials, and subscription changes.
• Pre-Built SaaS Templates: Ready-made flows for welcome series, onboarding, payment recovery, cancellation win-backs, and feature announcements tailored to subscription models.
• Smart Segmentation: Real-time segments update based on user behavior, tags, and custom attributes, with Send Time Optimization for peak engagement.
• Developer Tools: REST API, SDKs for TypeScript, Python, Go, PHP, and Java, plus an MCP server for AI assistants like Claude, Cursor, and Windsurf.
• Visual Automation Builder: Drag-and-drop editor for designing flows with triggers, conditions, and branching, no code required.
• Unified Email Management: Handle both marketing campaigns and transactional emails (password resets, receipts, notifications) from a single dashboard.
• Custom Sending Domains: Included on all plans (even free), with automatic DNS verification and DKIM, SPF, and DMARC authentication.

• Purpose-Built for SaaS: Understands MRR, churn events, and subscription lifecycles out of the box, unlike tools adapted from e-commerce workflows.
• Generous Free Plan: 2,500 emails per month with unlimited contacts and no credit card required beats most competitor free tiers.
• Transparent Volume-Based Pricing: Costs scale with email volume sent, not contact count, making it affordable for large audiences.
• Developer-First Approach: Full API access, multi-language SDKs, and MCP integration on all plans make it flexible for technical teams.

• Best Suited for SaaS-Focused Teams: Built for SaaS founders and product-led teams, so e-commerce stores and content marketers may find it less suitable.
• AI-Generated Content Still Needs Editing: While the AI Sequence Builder speeds up setup, generated content often benefits from human editing for brand voice.

• Trial-to-Paid Conversion: SaaS founders can generate a full trial nurture sequence by describing their product and target user, then let Sequenzy handle timing and messaging to boost conversion rates.
• Failed Payment Recovery: Automatically trigger dunning emails when Stripe or Paddle reports a failed charge, recovering revenue that would otherwise churn silently.
• Onboarding New Users: Deploy pre-built welcome flows that guide new signups through key product features and activation milestones without manual setup.
• Cancellation Win-Backs: Send targeted campaigns to users who cancel subscriptions, offering incentives or feedback surveys to reduce churn.
• Transactional Email Delivery: Handle programmatic emails like password resets, receipts, and system notifications through the same platform as marketing campaigns.
• AI-Assisted Campaign Creation: Developers using Claude, Cursor, or Windsurf can build and manage email sequences directly from their AI assistant via the MCP server.
