How addressees are selected
Each row is addressed to a decision maker at the company. We select the best person using this priority:
- Current Director - The longest-serving director still in post (non-corporate preferred)
- Current Secretary - If no directors, the company secretary
- Other Current Officer - Any other officer currently in post
- Fallback - "Business Owner" when no officers are on file
Address source
The address used is always the company's registered office address from Companies House, not the officer's personal address. This ensures mail reaches the business location.
Use cases

Search for companies by industry, location, or size, then send introductory letters or brochures directly to decision makers.

Data quality notes
Important: Verify addresses before large campaigns
Companies House addresses are self-reported and may be outdated. Some companies use registered agent addresses rather than their actual business location. For large campaigns, consider using address verification services offered by your mail provider.
Missing addresses
Some companies may have incomplete address data. These rows will have empty fields in the CSV, and most mail providers will flag them as undeliverable during upload.
Corporate officers
When a company's only officers are corporate entities (other companies), the addressee name will be the corporate officer's name rather than a person's name.
Companies with no officers
For companies with no current officers on file, the addressee defaults to "Business Owner".
