Sendkit
Email API & Marketing Platform built for developers, marketers & AI agents
About Sendkit
Sendkit is an email platform that brings transactional email, marketing campaigns, automations, and contact management into a single API. It is built for developers, marketers, and AI agents, offering SDKs for 10+ programming languages, an SMTP relay, real-time webhooks, and a native MCP server for AI integration. The platform supports sending at scale with features like open/click tracking, suppression management, and deliverability optimization through SPF, DKIM, and DMARC. Pricing is transparent with a free tier of 3,000 emails per month and no credit card required. Paid plans start at $15 per month for transactional and $30 per month for marketing, with unlimited contacts and overage charges at $1 per 1,000 emails. The platform is designed to replace stitching together multiple tools like Postmark, Mailchimp, and Zapier, offering a cohesive solution for email needs. For deployment, Sendkit leverages Cloudflare's edge network and managed sending infrastructure to ensure low latency and reliable delivery. With its MCP server, AI agents like Claude and Cursor can manage email operations through natural language. The platform is ideal for startups, SaaS teams, and enterprises that need a robust yet simple email solution. As part of AiDOOS, Sendkit can be integrated into broader workflows to enhance deployment and adoption, providing a scalable email backbone for various applications.
