How to pick a category
Look for categories where companies sell to the public, compete on reputation and spend on marketing. Those are the ones that answer cold outreach about growth, reviews and customer experience.
Categories worth starting with
| Category type | Example IDs | Typical needs |
|---|---|---|
| Solar and energy | solar_energy_company | Lead gen, appointment setting, reviews |
| Home improvement | roofing_contractor, plumber, electrician, hvac_contractor | Local SEO, review management, call handling |
| Online shops | clothing_store, furniture_store, jewelry_store | Ads, email marketing, CRO, UGC video |
| Software | software_company | Content, SEO, sales development |
| Finance, insurance and legal | insurance_agency, accounting_firm, law_firm | Compliance-friendly marketing, lead nurturing |
| Travel | travel_agency | Seasonal campaigns, review replies |
| Agencies | marketing_agency, website_designer | White-label partners, tools |
Category IDs come from the Trustpilot address (trustpilot.com/categories/<id>). The Trustpilot Scraper suggests common ones under the search box.
Narrow it down
- Country — match your market and language.
- City — for local services.
- 4+ TrustScore and claimed — established companies with someone in charge.
- Min. reviews — 50+ filters out dormant profiles.
A simple plan
- Pick one category that matches your best past clients.
- Pull 200–500 companies with a 4+ score in your country.
- Keep those with an email and an owner name.
- Write one offer for that category — see write a cold email offer.
- Measure replies, then add the next category.
