High Conversion B2b Cold Email Copywriter Prompt

What it does

This prompt instructs the AI to act as an expert B2B cold email copywriter and, using your provided business inputs (target persona, core problem/value hook, product details, tone preferences, and optional relevance triggers), produce three high-open-rate subject line options plus a concise 100–150 word personalized cold email. The resulting email is designed to feel natural and non-fluffy, lead with an ICP-relevant hook, include a standout insight or stat, connect the offering directly to the recipient’s pain point, spark curiosity rather than oversell, and finish with a clear low-friction call to action, optionally capped with a brief P.S. for personality or urgency.

Inputs

textInputs

Pass each text input using --input <key>=<value> flags.

Models and options

This skill's modality is: text.

To discover which model values you can use (and which options keys/values are valid for each model), run:

betterprompt resources --models-only --json

Then filter the returned JSON array to entries where modality is "text".

How to run

Step 1: Collect inputs

First, run betterprompt resources --models-only --json and filter to modality: "text" to discover valid models and available options:

betterprompt resources --models-only --json

Use only the models and option values that appear in the filtered results.

Then collect all inputs from the human:

• Required text inputs:
  • Action
  • Product
  • Preference
  • Target_Persona
  • Core_topic_or_problem
  • Trigger_for_relevance
• Optional: model and options.
  • Present the human with the default model gpt-4.1-mini and its available options. Look up gpt-4.1-mini in the betterprompt resources output (filtered to modality "text") and show its availableOptions as: key: val1, val2 (default), val3 | key2: .... Mark a value (default) if it matches these defaults: {}.
  • If the human does not specify, defaults are used: model gpt-4.1-mini, options {}. Other models from the resources call are also available.

If any required text input is missing, ask the human for what's missing. Do not assume or fabricate values.

Step 2: Run via BetterPrompt CLI

Use the frontmatter's name as the positional argument (for this skill, use high-conversion-b2b-cold-email-copywriter-prompt).

Command form:

betterprompt generate high-conversion-b2b-cold-email-copywriter-prompt \
  [--input <key>=<value>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]

Notes:

• Pass each text input as a separate --input <key>=<value> flag.
• If the human does not mention a model, omit --model and BetterPrompt will use the default model: gpt-4.1-mini.
• If the human does not mention options, omit --options and BetterPrompt will use the default options: {}.
• If the run times out, the response will include a runId you can use to fetch the result later.

Example (using defaults shown above):

betterprompt generate high-conversion-b2b-cold-email-copywriter-prompt \
  --input Action=<value> \
  --input Product=<value> \
  --input Preference=<value> \
  --input Target_Persona=<value> \
  --input Core_topic_or_problem=<value> \
  --input Trigger_for_relevance=<value> \
  --model gpt-4.1-mini \
  --options '{}'
