What is lemwarm?

lemwarm is the email warmup product from lemlist, designed to protect sender reputation by exchanging automated emails with a network of more than 20,000 real inboxes across over 150 countries. It gradually raises daily sending volume up to a 40 email cap, tracks a deliverability score, and checks technical settings such as SPF, DKIM, and DMARC along with blacklist status.

The Smart plan adds personalized warmup emails and the ability to warm up actual campaign templates before they go out to real prospects, plus industry tailored warmup clusters. lemwarm is billed per inbox and is included at no extra cost for subscribers on lemlist's Email plan or higher, while non lemlist users can subscribe to it as a standalone tool.

lemwarm FAQs

Yes, every lemlist plan includes lemwarm at no extra cost, so lemlist subscribers get warmup covered automatically.

Yes, lemwarm is available as a standalone subscription priced per inbox for users who are not on lemlist.

Most inboxes reach the full sending volume cap in 3 to 4 weeks, then stabilize for about 2 more weeks before campaigns start.

Smart adds personalized warmup emails, real template warmup, custom deliverability alerts, and industry-tailored warmup clusters.

Sender reputation gradually drops if warmup stops, so it is meant to run as ongoing maintenance rather than a one-time fix.
