Read, sort, and send email with an AI assistant
Email servers give an assistant access to an inbox through Gmail, Outlook, IMAP, or a sending service such as Resend or SendGrid. Inbox servers can search threads, summarize unread mail, draft replies, and apply labels. Sending servers are aimed at developers who want an agent to send notifications or test transactional templates. Even a daily summary of what needs a reply saves real time. Mail is sensitive, so prefer servers that create drafts instead of sending directly, use app passwords or OAuth rather than your main password, and review anything going to a customer.
Example prompts
Paste one into Claude, Cursor, or any MCP client once a matching server is installed.
Summarize the unread emails in my inbox and flag the ones that need a reply today.
Draft a polite reply to the latest email from the accounting team.
Find all receipts from last month and list the vendor and amount for each.

How to set it up
- Pick a server. OpenLeads is the strongest match. Check its tools and the API keys it needs on its page.
- Copy the config for your client. Open the install guide for Claude Desktop, Claude Code, Cursor, or VS Code, and paste the generated block into the client's config file. The client guides show where each config file lives.
- Restart and try a prompt. Restart the client so it loads the server, then paste one of the example prompts above.
Questions about email automation
What is the best MCP server for email automation?
OpenLeads ranks first here with a trust score of 74/100, followed by email-smtp-imap-mcp (74) and email (69). Servers that name the topic directly come first, each group ordered by the public trust score, which nobody can pay for. See the methodology for how it is calculated.
How do I set up OpenLeads in Claude or Cursor?
Open the install guide for Claude Desktop or Cursor, copy the generated config into the client's config file, add any API keys the server asks for, then restart the client. The client guides cover VS Code, Claude Code, Windsurf, and more.
Can I use a hosted server instead of installing one locally?
8 of the 12 servers listed here can connect remotely over HTTP, so there is nothing to run on your machine: Sendgrid, Local MCP, Emailable, and others. The rest run locally over stdio.
