Instantly

Instantly combines cold email automation with account warmup via a network of 200,000+ real inboxes. The platform rotates through residential IP addresses using SISR infrastructure, mirroring the sending patterns of legitimate accounts rather than jumping straight into full-volume sends. This approach rebuilds reputation gradually before launching campaigns.

Designed for sales teams and agencies scaling outbound email without landing in spam. The warmup component sets it apart from basic cold email tools, addressing the core blocker most new senders face. Integrates with CRM data to personalize sequences while keeping inbox health in focus from day one.
