Frequently asked questions about the Mailsac MCP Server

What is an 'Enhanced' address in Mailsac?

An enhanced address is a private inbox that only you can access. Use the reserve_new_address tool to make an address private/enhanced.

Can I read the raw SMTP source of an email?

While this server provides tools for HTML and Plain Text bodies, the Mailsac API supports raw data retrieval. You can use the text body tool to extract key technical metadata.
