Frequently Asked Questions

Can Claude Code actually send emails?

Yes, but not natively. Claude Code sends email through MCP servers that connect it to an email provider. Popular options include the Resend MCP for transactional mail, a Google Workspace MCP for Gmail, and an Outlook MCP for Microsoft 365. Once a server is added to your config, Claude can compose and send messages on your behalf.

What is the easiest way to send email with Claude Code?

The Resend MCP is the simplest setup. Create a free Resend account, generate an API key, verify your sending domain, then add the resend/mcp-send-email server to Claude Code. After that you can prompt Claude to send messages in plain language. To send from your own Gmail, use a Google Workspace MCP instead.

How do I send email from my Gmail account with Claude?

Use a Gmail-capable MCP server such as the Google Workspace MCP (taylorwilsdon/google_workspace_mcp). Run it with 'uvx workspace-mcp --tool-tier core', then authenticate with your Google account via OAuth 2.0 in a browser. It works with both free Gmail and paid Workspace accounts, so Claude can send, read, and search your real mailbox.

Are there limits on how many emails Claude can send?

Yes, and they come from your email provider, not Claude. Free Gmail accounts allow about 500 emails per day; Google Workspace accounts allow 2,000 per day on a rolling 24-hour window. Transactional providers like Resend have their own plan-based quotas. For bulk or automated sending, a transactional API is safer than Gmail to avoid deliverability issues.
