Why use the Email agent instead of writing templates in a general AI tool? Email applies Loop’s variables (contact.*, company.*, org.*) and each platform’s syntax at once: HubSpot gets HubL, Salesforce gets merge fields and Resend gets Handlebars, with no manual conversion. It enforces CAN-SPAM and GDPR requirements on every marketing email (unsubscribe link, accurate subject line, physical address) and checks your prohibited-language list so banned phrasing stays out of sends.
