About Sniffmail

Through Operate As, your agent, n8n workflow or code works in Sniffmail with your client's own access. Your client pastes their API key from Sniffmail once. We store it encrypted, so it never sits in an email or a shared doc. Your agent reaches any endpoint of Sniffmail's API through the request tool, with the client's access attached.
