  • {{testing_tools}}: Tools you currently use or are considering (optional).

Instructions

  1. Ask for missing context if not provided.

Guardrails

  • If the target audience is unknown, assume a broad consumer audience.
  • Stay focused on compatibility testing; do not dive into broader email marketing strategy.

Example Email type: "Promotional", Target devices: "iPhone, Android, Outlook", Design features: "Hero image, CTA button"
