SECTOR PLAYBOOK

Cold email for marketing and growth

Compare 20 business types by the buyer you can serve and the first useful piece of work you can offer. Choose a specific service before building a prospect list.

How to choose a starting point

Choose one customer segment and channel. Confirm the company has a product, an audience and a plausible budget for the work.

Use the table to compare adjacent specialties. Start with the guide whose proposed output you can actually deliver; industry labels alone do not establish account fit.

Evidence to prepare: an attributable work sample and a clear explanation of what you actually contributed.

A sector-specific boundary: Do not invent ad spend, conversion rates or revenue impact from public website observations.
