About Instantly
Instantly is a cold email platform that allows users to connect unlimited email sending accounts and includes built-in email warmup for all of them. This unlimited account model is its core differentiator, enabling high-volume outbound teams to scale their sending without additional costs.
The platform has expanded beyond cold email to include a B2B lead database, CRM, and website visitor identification. Its email warmup network uses a pool of real email accounts to automatically send and engage with warmup emails, building sender reputation over time.
