Short answer: E-Warmup is the better standalone email warmup software. Lemwarm is a module inside Lemlist. If you're not already paying for Lemlist, E-Warmup offers 7.5x the daily warmup volume, more deliverability features, and a Free Forever plan at lower cost.
Lemwarm Essential: $29/inbox/month, 40 emails/day cap. Lemwarm Smart: $49/inbox/month, same 40/day cap. E-Warmup Growth: $99/month for 3 mailboxes at 300 warmup emails per day per mailbox.
The 40 emails/day cap is the biggest limitation in Lemwarm's automated email warmup. For new domains or sender reputation recovery, that pace is slow. E-Warmup Growth sends 7.5x the throughput, meaning faster email domain reputation building and shorter warmup cycles before live cold email deliverability campaigns.
At 3 inboxes:
Lemwarm Smart: $147/month (3 x $49)
E-Warmup Growth: $99/month
Plus E-Warmup includes inbox placement testing (Lemwarm: none at any tier), AI-powered blacklist removal, warmup bounce protection, sender reputation monitoring, and AI-adaptive warmup content that responds to live domain signals. Lemwarm uses a fixed warmup curve that doesn't react to your sender reputation score.
If your team is already on Lemlist Email Pro ($79+/month), Lemwarm is included free. That's the strongest reason to choose it. The Smart Cluster feature for industry-matched warmup partners is also a credible differentiator for sender reputation building inside specific niches.
