What is Instantly?
Instantly.ai is a cold email and lead generation platform founded in 2021. It is built around native inbox rotation — connecting 10–100+ email accounts to a single sequence and rotating sends to protect deliverability.
Instantly is the dominant choice for agencies and SMB lead-gen shops running high-volume cold email (1,000+ sends/day per account). It has a flat monthly pricing model that suits agency economics.
Instantly explicitly covers the cold email and deliverability layer — not signal detection, call workflow, or CRM hygiene.
