Lemwarm

Lemwarm warms up cold email accounts by sending and receiving messages across a network of partner inboxes. The platform tracks engagement metrics and pauses warmup automatically during high-volume campaign periods to avoid throttling issues. ESP-specific reporting lets you monitor warmup progress directly within your own tools.

For outreach teams managing multiple accounts, Lemwarm fits between basic warmup and full-stack cold email platforms. It works well as a foundational layer for any email sending tool, from general ESPs to dedicated cold email software, making it practical for teams already invested in their own sending infrastructure.
