What does the Email agent do? The Email agent writes production-ready email templates across every type: transactional system notifications, marketing campaigns, cold outreach cadences, drip nurture sequences, event invitations, newsletters, and win-back programs — with full {{contact.*}} variable mapping, fallback patterns for every merge field, and platform-specific export syntax for HubSpot, Salesforce, Marketo, Pardot, and Mailchimp.
