FAQ
Questions Mailsac owners ask.
- 01
What is an 'Enhanced' address in Mailsac?
An enhanced address is a private inbox that only you can access. Use the reserve_new_address capability to make an address private/enhanced.
- 02
Can I read the raw SMTP source of an email?
While this server provides capabilities for HTML and Plain Text bodies, the Mailsac API supports raw data retrieval. You can use the text body capability to extract key technical metadata.
- 03
Is an API Key required for all addresses?
Yes, this MCP server requires an API Key to interact with your account and access your reserved resources and private messages.
