What is AutoSend?

AutoSend is an email platform built for developers who need reliable transactional and marketing emails without the usual pricing headaches. It combines transactional email delivery, marketing campaigns, and automated workflows into a single API-first service. The platform is designed to work seamlessly with AI agents, offering integrations like MCP and skill.md so that agents can build templates, manage contacts, and monitor delivery stats programmatically.

Who it's for

• Startup founders who need a scalable email solution that won't spike in cost as their user base grows.
• AI/LLM developers building agent-driven applications that require programmatic email sending and template management.
• Engineering teams shipping products with high email volume who want predictable pricing based on volume, not contact count.

Key features

Transactional email API

Send OTPs, alerts, and updates with a clean REST API that prioritizes speed and reliability. The API supports both template-based sending and raw HTML or text, with built-in unsubscribe group compliance for transactional messages.

Marketing campaigns

Create, personalize, and send newsletters or product launch emails to targeted audiences. The campaign dashboard shows past sends with subject lines and timestamps, making it easy to track performance.

Email automation

Set up welcome sequences, onboarding flows, and re-engagement campaigns that run automatically. These workflows handle the entire conversion-to-retention cycle without manual intervention.

Agentic integrations

AutoSend works with your favorite AI agents through MCP and skill.md, giving agents full knowledge of the API and best practices. This allows LLMs to send transactional emails, manage contacts, and monitor delivery stats as naturally as a human would.

What stands out

"We chose AutoSend for its first-class email handling for LLMs and AI agents, unlike generic tools."

AutoSend is purpose-built for the agent era. While other platforms treat AI integrations as an afterthought, AutoSend provides native MCP support and a skill.md file that gives agents complete API knowledge. This means your AI can build templates, create campaigns, and monitor delivery without you writing glue code. Combined with pricing based on volume rather than contact count, it's a rare combination of developer-friendly design and cost predictability.

Worth checking out if…

You're building with AI agents and need an email platform that speaks their language. AutoSend is also a strong choice if you're tired of contact-based pricing models that penalize growth, or if you want a single platform for transactional, marketing, and automated emails without juggling multiple providers.
