Instantly AI

Instantly is a sales engagement platform built around cold email outreach, combining lead sourcing, email deliverability tools, and campaign automation in one system. Users can find prospects through a database described as covering more than 450 million contacts, verify email addresses, and launch multi-step outreach sequences from unlimited sending accounts on every plan. A built-in warm-up system works to protect deliverability as sending volume grows, and an AI Sales Agent and AI Reply Agent can automate parts of the outreach and response process. Beyond email, the platform's CRM extends into calling and SMS, letting sales teams manage multiple channels without switching tools, and it includes website visitor tracking and workflow automation triggered by prospect actions like site visits or meeting bookings. It reports revenue metrics such as pipeline and conversions rather than only email opens and clicks. Instantly is aimed at sales development teams, agencies, and founders running outbound campaigns at scale, particularly those sending high volumes of email and needing inbox rotation to avoid deliverability problems. A public API is available for developers who want to integrate the platform into other systems. One limitation is that detailed pricing isn't published on the main site; visitors are directed to a separate pricing page and a free trial before seeing full plan costs.
