Sidemail Email MCP Server connects AI tools like Claude, VS Code, Cursor, or Windsurf to your email stack. Ask your agent to set up transactional email sending, write newsletters, manage contacts and groups, or verify sending domains – all via MCP, backed by Sidemail’s proven email infrastructure.
Hi Hunters!
I'm Kristyna, maker of Sidemail. I'm happy to share with you what we've been building.
AI is on the rise, and so is MCP – letting developers plug AI tools into real-world infrastructure and save a lot of time and resources.
To make email delivery even easier, we built Sidemail Email MCP Server.
It enables you to programmatically send and manage transactional emails, contacts, sending domains, and Messenger features – right 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 that signed up today to the Early Adopters group."
- "Create a new sending domain for myproduct.com."
The AI agent handles the steps for you – it retrieves data, calls the right email API methods, and asks for confirmation before final actions. Keeping you in control.
It all runs on Sidemail’s proven email infrastructure for reliable delivery, tracking, and scalability, so every message reaches its destination.
If you have any questions or thoughts to share, please do tell! We're used to working with customers and are always happy to improve further.
Thank you!
Kristyna 💙
