## How does the Email agent handle my contact data and brand voice?

Contact data is never stored by the agent — it writes templates with variable placeholders that your ESP (HubSpot, Salesforce, Resend) resolves at send time. Your brand voice is loaded from your @brand-guidelines document in your workspace before any copy is written, then adapted to email’s more personal, 1:1 register.
