Comparison
Lemwarm is lemlist's warmup tool. It still sells standalone, priced per mailbox, but lemlist now includes Lemwarm with its paid plans, so for many lemlist customers it costs nothing extra. Warmerly is the pick when you do not use lemlist, or want one flat price across many mailboxes.
The cheaper alternative with published prices: warmup included on every mailbox, daily SPF, DKIM and DMARC checks, and campaigns from the same mailboxes.

If you already pay for lemlist, use the Lemwarm that comes with it. It is included in your plan, it is native to the tool you send from, and nothing here is worth a second bill. The case for Warmerly starts when you do not use lemlist, or when you have more mailboxes than your lemlist seats cover. Standalone, Lemwarm is $145 a month for 5 mailboxes and $725 for 25, against $19 and $49 on Warmerly, and Warmerly adds daily auth monitoring, a campaign sender with no cap on sends and LinkedIn steps in the same sequence. The Lemwarm figures are its published prices; whether a free bundled account covers every extra mailbox you add depends on your lemlist plan, so check that before you compare.
Per lemlist's pricing page, Lemwarm and its built-in deliverability protections are included in its plans. lemlist's help center says you can warm several email addresses under the lemlist bundle, up to your plan's limit: unlimited senders on the Email plan, and up to 5 email addresses per user on Multichannel Expert and Enterprise. Confirm in your lemlist account.
Standalone on Essential, 5 mailboxes is $145 a month ($120 on annual billing) and 25 is $725 ($600 annually). Smart is $49 per mailbox monthly. Warmerly is $19 for 5 mailboxes and $49 for 25, with warmup on every mailbox.
Yes. Leave Warmerly's campaigns off and it only warms the mailbox. lemlist can run campaigns from the same Gmail or Microsoft account, with no DNS or routing changes. Do not warm one mailbox in both tools at once, since two networks sending warmup mail from one address muddies the results.
Mailbox reputation lives at Gmail and Microsoft, not at the warmup tool. Switching does not reset it. Warmerly picks up where Lemwarm left off and continues building.
Turn off warmup for the mailbox in Lemwarm, connect it to Warmerly through the Google or Microsoft sign-in, and pick a ramp curve that matches your current sending volume. About 2 minutes per mailbox, no DNS changes. If you keep sending from lemlist, leave Warmerly's campaigns off.
Connect a mailbox to Warmerly in 60 seconds. Free plan, no card required. Paid plans start with a 7-day trial, first charge on day 8, cancel any time before then. We will warm right alongside whatever you use now, so you can A/B without commitment.
