Instantly
Cold email at scale with unlimited sending accounts and smart delivery
Overview
Instantly focuses on the core challenge of cold email: getting your messages delivered and read at scale. Connect unlimited sending accounts, and Instantly rotates between them to maintain healthy sender reputation. The automated warm-up system gradually builds each account's credibility before you send.
The 450M+ B2B lead database means you can find prospects and launch campaigns without switching to a separate data provider. Filter by industry, company size, job title, technology used, and other criteria to build targeted lists that align with your ideal customer profile.
For teams doing high-volume outbound, Instantly's approach to email infrastructure management is its key differentiator. Most cold email tools focus on the sequence builder - Instantly focuses on making sure your emails actually reach the inbox.
