Data transparency
A clearer view of
our data sources.
An overview of the sourcing channels used by Latest Mailing Database for business and consumer contact data.
Sources, research tools and verification serve different purposes.
The channels behind our data.
Public information & websites
Publicly accessible information and website research, including website crawling.
Social media
Information obtained through social media research.
Job portals
Information obtained through job-portal research.
Market research
Information gathered through market-research activities.
Crowdsourced information
Information contributed through crowdsourcing channels.
Data partners
Information received from data partners.
These categories describe our stated sourcing channels. They do not mean that every record comes from every channel or that each channel applies equally to B2B and consumer records.
Research tools
Tools help us research.
They are not a source guarantee.
Our research workflow includes contact-discovery and AI-assisted tools, including ContactOut AI search.
Naming a tool does not imply a partnership, endorsement or a particular licence to redistribute its data.
Sourcing and verification are separate.
We verify our email data monthly. Verification checks help assess data; they do not establish its source or permission for a particular marketing use. Public availability alone does not establish permission to contact someone.
