Lemwarm

Lemwarm is lemlist's email warmup and deliverability tool that automatically exchanges real emails across a network of 20,000+ domains to build sender reputation before outreach campaigns. It reports a deliverability score over time, checks SPF/DKIM/DMARC authentication, and tracks inbox-versus-spam placement. It is available as a standalone per-inbox subscription and is also bundled into paid lemlist plans.
