How do I configure an SMTP server?

Use the `add-smtp-config` tool with parameters for host, port, security (SSL/TLS), and authentication credentials (user and pass). You can also set it as the default configuration.

Can I send bulk emails with SMTP Email MCP Server?

Yes, use the `send-bulk-emails` tool. You can specify recipients, batching parameters (`batchSize`, `delayBetweenBatches`), and optional SMTP config or template.

What credentials does it need?

It reads `NODE_PATH` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
