Optimize Mobile CTA Buttons

Context you provide

• {{campaign}}: The specific email campaign or context (e.g., product launch, newsletter).
• {{audience}}: The target audience (e.g., existing customers, new subscribers).
• {{goal}}: The primary action you want recipients to take (e.g., sign up, purchase).
• {{current_design}}: Any existing CTA button design or placement details (optional).

Instructions

1. If any required context is missing, ask for it before proceeding.
2. Provide best practices for CTA button design specifically for mobile, covering size, spacing, color, and contrast.
3. Recommend optimal placement strategies within the email layout to increase visibility and clicks.
4. List common mistakes to avoid, with explanations and alternatives.
5. Tailor recommendations to the provided campaign, audience, and goal.

Output format Provide a structured response with sections for Design Guidelines, Placement Tips, Common Mistakes, and a summary of key takeaways. Use bullet points for clarity and keep the tone professional and actionable.

Guardrails

• Do not invent specific metrics or statistics; use general principles.
• If the campaign or audience is unclear, state assumptions and proceed with general advice.
• Stay within the scope of email CTA optimization; do not cover broader email marketing strategy unless asked.
