In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
These are multiplications
Lemwarm's page shows a per-mailbox price only. The totals here are that price times the count, with no discount applied.
Annual maths at 25 mailboxes
Growth billed monthly is $49 x 12 = $588 a year, and $490 billed yearly. Lemwarm Essential at 25 mailboxes is $8,700 on monthly billing and $7,200 on its yearly option. The gap is $6,710 to $8,112 a year depending on how each side is billed.
Smart at 10 mailboxes
Ten Smart mailboxes are $490 a month, $5,880 a year, against $49 a month on Warmerly Growth. That is a $441 monthly gap, which only makes sense if you rely on template warm-up and an industry network.
An agency with 100 mailboxes
A hundred mailboxes on Warmerly Agency is $179, with client workspaces and API access. Lemwarm Essential at 100 would be $2,900 a month, so Custom pricing would be the real conversation, and no figure is shown.
Where the gap closes
At one mailbox the gap is smallest: Warmerly is free, or $19 on Starter if you expect to grow, against $29 or $24. For one or two mailboxes, other features decide more than price.
A sender is extra on Lemwarm
Lemwarm's price excludes a campaign sender. If you need one, lemlist's Email plan is shown at $69 and $55 a month, or you can compare with Warmerly's all-in price instead.
