Instantly is an AI-driven cold email outreach platform designed to help B2B sales teams, agencies, and growth marketers scale their email campaigns without sacrificing deliverability. The platform allows users to connect unlimited email sending accounts under a single dashboard, automatically warming them up to build sender reputation and avoid spam folders. Its Campaign Builder supports smart sequences with personalization variables, A/B testing, and automated follow-ups. Instantly also includes a built-in lead database with over 160 million verified B2B contacts, enabling users to find and target prospects directly within the platform. A unified inbox (Unibox) streamlines reply management across all accounts.
