CampaignAn organized email outreach effort targeting a group of contacts. Campaigns can include multiple emails, A/B testing, scheduling, and detailed analytics for open rates, click rates, and conversions.Cold LeadAn unconsented, not-yet-contacted prospect that lives only inside Cold Outreach, on an imported or manually added list. Cold leads are deliberately isolated from the CRM: they do not appear in company or people search, dashboards, or automations, and can be bulk-purged. This is the opposite warmth of the CRM "Lead" lifecycle stage, which marks a consented or engaged contact. A cold lead enters the CRM only through Promote, which creates a contact with a pending consent record.ContactA person record in the CRM, typically associated with a company. Contacts store personal details, communication history, and activity timelines.Contact GroupA saved list of contacts used for bulk operations such as campaigns, exports, or targeted outreach. Groups can be static (manually curated) or dynamic (automatically updated based on filter criteria).Custom FieldA user-defined data field added to entities (companies, people, opportunities) beyond the default system fields. Custom fields support text, number, date, dropdown, and other types.
