Safe by design
Your sign-in, your permissions
You sign in on the MailSenpai page with OAuth and PKCE: the AI client never sees your password or any API key. The assistant only gets the permissions of your plan and role.
You approve what matters
Campaigns start as drafts. Sending, scheduling and deleting happen only after your explicit confirmation, and only if your plan allows them.
Transparent and private
Every action is logged and rate limited. Your data is not sold and is not used to train AI models. You can disconnect the assistant at any time.
