Best for warming up sending inboxes
Lemwarm warms up your sending inboxes by swapping emails with a network it says spans over 20,000 real domains, and it tracks a deliverability score. It does that one job. It is $24 a month for each inbox on yearly billing, with no free plan or trial, and personalized warm-up emails need the $40 Smart plan.
Who Lemwarm is for
- Fits if you send cold email from a few inboxes and want them warmed up
- Works for lemlist users, since every lemlist plan already includes it
Who Lemwarm is not for
- Skip it if you want to try it first, as there is no trial or free plan
- Pricey if you run many inboxes, because the price is per connected email address
- Too light for finding leads or sending campaigns, which need other tools
- Watch out: personalized warm-up emails and warming your own templates need Smart at $40 an inbox
Why Lemwarm gets a 1.6
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- BValue for money$24 an inbox a month on yearly billing ($29 monthly), just under the $25 that opens the cheaper quarter of cold-outreach tools. It is priced per inbox, so ten inboxes cost $240.
- FFree plan and trialNo free plan and no trial on the pricing page.
- DFeaturesWarm-up, a deliverability score and a setup check, and nothing else. It needs a separate tool to find leads and send campaigns.
- CEase of useNo store rating on record. You connect each mailbox and read the reports.
- CPlatforms and integrationsWeb only, and the listing names no integrations.

Keep Lemwarm, or make your own?
Keep it
To replace Lemwarm you would be making a network of real inboxes that open and answer your emails. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 64 of the 81 other cold outreach tools grade higher. It costs $288 a year.
What you could not
- A network of real inboxes that open and answer your emails.
- Newsletters sent to thousands of people that still reach the inbox.
- Reading the reports inbox providers send about your domain.
What this rests on. Lemwarm’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
