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