Quick Reference: Who We Studied

Source

1. Assign a Crystal-Clear Role & Persona

Clearly defining your AI's role transforms its output from vague to precise.

Example from Bolt:

“You are Bolt, an expert AI assistant and exceptional senior software developer with vast knowledge across multiple programming languages, frameworks, and best practices.” (Bolt)

Why this matters in email marketing: Give your AI a clear identity (e.g., "InboxWhisperer, a senior retention copywriter specializing in high-ROI win-back campaigns") and your copy instantly aligns with expectations.

2. Use Brutally Explicit Rules

Unambiguous instructions eliminate guesswork and reduce AI errors significantly.

Example from Bolt:

“CRITICAL: Third-party libraries cannot be installed or imported.” (Bolt)

Example from Cursor:

“ALWAYS follow the tool call schema exactly as specified and make sure to provide all necessary parameters.” (Cursor)

Why this matters in email marketing: Use similar absolute directives, such as “ALWAYS include a CTA button above the fold,” or “NEVER exceed 60 characters in your subject lines.”

3. Think in Tools, Not Tasks

Prompting AI effectively means explicitly specifying tools and sequencing.

Example from Manus:

“Iterate: Choose only one tool call per iteration, patiently repeat above steps until task completion.” (Manus)

Example from GitHub Copilot:

“If a tool exists to do a task, use the tool instead of asking the user to manually take an action.” (GitHub Copilot)

Why this matters in email marketing: Think of Klaviyo integrations, image generation, or Shopify product pulls as your AI's tools (Raleon provides these integrations out-of-the-box, by the way). Clearly instruct it to sequence tasks, e.g., “First pull product details, then draft email copy, finally create a promotional image.”

4. Guarantee Safe, Runnable Output

Always prompt for complete and immediately actionable content. No placeholders!

Example from Bolt:

“CRITICAL: ALWAYS provide the FULL, updated content of the artifact... NEVER use placeholders.” (Bolt)

Example from Cursor:

“It is EXTREMELY important that your generated code can be run immediately by the USER.” (Cursor)

Why this matters in email marketing: Demand fully-formed HTML snippets or Klaviyo-ready email templates without placeholders, ensuring your outputs are instantly usable.

5. Gather Context Autonomously

Empower your AI to independently fetch necessary context.

Example from Cursor:

“If you need additional information that you can get via tool calls, prefer that over asking the user.” (Cursor)

Why this matters in email marketing: Instead of repeatedly pasting context, instruct your AI: “ALWAYS fetch customer's recent purchase data via API before drafting.” This automates personalization effortlessly.

Better yet, just use Raleon. Raleon's AI Strategist continuously updates its knowledge of your brand, your customers, and your data, including a Memory feature that learns directly from what you teach it in every chat session. 

6. Lock in Tone & Safe Refusals

Predefine how your AI handles inappropriate or off-brand requests to maintain consistency.

Example from GitHub Copilot:

“If you are asked to generate content that is harmful, hateful, racist, sexist, lewd, violent, or completely irrelevant... respond only with 'Sorry, I can't assist with that.'” (GitHub Copilot)

Example from Bolt:

“Do NOT be verbose and DO NOT explain anything unless the user is asking for more information.” (Bolt)

Why this matters in email marketing: Set similar guardrails for compliance, like “NEVER include medical claims in marketing emails” or “ALWAYS refuse non-CAN-SPAM compliant requests succinctly.”

7. Leverage Memory & Environment Cues

Instruct your AI to utilize persistent memory or available environmental context.

Example from Windsurf:

“You have access to a persistent memory database to record important context about the USER's task, codebase, requests, and preferences for future reference.” (Windsurf)

Why this matters in email marketing: Store your Brand Voice Card once, then instruct your AI: “ALWAYS reference brand voice from persistent memory.” You can save your Brand Voice Card in a Project on Claude or ChatGPT - or even better, let Raleon manage it for you, automatically. Now, every prompt effortlessly maintains a consistent tone and style.
