Show HN: Email MCP Server (Works with Claude/VS Code/Cursor/Windsurf)

[slonik]

Hi everyone! I’m Kristyna, building Sidemail.

My goal is to make emails as easy as possible for startups.

Made an email MCP server (open-source). It enables programmatic setup of transactional email sending, writing newsletters, managing contacts, and configuring sending domains – all from MCP agent mode in VS Code, Claude, Cursor, Windsurf, and other MCP clients.

That means you can say things like: - Write a product update from our changelog and schedule a delivery to our paying customers for tomorrow at 2 PM - Add these users who signed up today to the Early Adopters group - Create a new sending domain for myproduct.com

The AI agent handles the steps – it retrieves data, calls the corresponding API, and asks for confirmation before final actions.

I'd love to hear your thoughts.

Thank you!
