The short answer
Campaign sending, in one look.
Warmerly sends campaigns from the mailboxes it warms, with sequences, pre-launch checks, one reply inbox and no cap on sends on paid plans, while Lemwarm only warms and lemlist is the sender. Warmerly is ahead if you want warmup and sending in one tool without lemlist. LinkedIn steps sit in the same sequence on a $19 per account add-on. Last checked 21 October 2026.

How Warmerly does it
Warmerly, in detail.
Sequences, pre-launch checks and one reply inbox.

Warmerly product, checked 21 October 2026
02
No cap on sends on paid plans
Starter, Growth and Agency send without a monthly meter. Each mailbox still sends inside its daily limit. Free is capped at 100 sends a month.

03
One reply inbox
Replies land in one inbox with LinkedIn replies. A genuine reply stops that lead's sequence by default.

04
LinkedIn is separate
A LinkedIn account is $19 a month on top of an email plan, with no trial.

05
Launch checks
Before Start, the campaign is checked for steps with content, sending accounts, queued leads, unknown merge tags, a campaign brief for an AI opener, and plan limits. Failures block the start.

06
Warnings need acknowledging
A DNS warning on a sender, more than 5 senders on one domain, a missing postal address, a missing tracking domain or spammy copy asks for one acknowledgement and does not block.

07
Replies stop the sequence
A genuine reply stops that lead's sequence by default, with separate settings for stopping on an auto-reply. A bounce stops sequencing and suppresses the address.

Connected mailboxes are read for new mail every five minutes, and replies appear in one inbox, including LinkedIn replies.

Starter sequences
The plain three-step intro sends an email, waits 3 days, sends a follow-up, waits 5 days and sends a last one, and needs no AI opener or brief.

A young mailbox starts small
If a campaign's mailboxes have had under 14 days of warmup, it starts at 3 emails per mailbox on day one and climbs. Mailboxes default to 30 sends a day.

How Lemwarm does it
Lemwarm, in detail.
Warmup only. Sending is lemlist's job.
01
Warm-up, monitoring and tips
The home page lists three jobs: warm-up, monitoring deliverability, and daily tips. It lists no campaign sender.

Warm-up volume next to campaigns

What lemwarm does not do
The home page lists warm-up, monitoring and deliverability tips, and names lemlist as the all-in-one outreach platform for email, LinkedIn, calls, SMS and AI-personalised sequences.

How the two run together
The setup article keeps lemlist at 0 during warm-up, starts it at 30 a day at launch with lemwarm at 10, and advises moving lemlist to 40 after a month of clean sending.

Keep warm-up on
The blog says to keep lemwarm on at 10 to 20 a day after campaigns start, and treat rising spam placement in lemwarm as a sign your campaigns are hurting the inbox.

lemlist's volume
lemlist's Email plan lists 50,000 emails a month and Multichannel unlimited emails and messages.

A switching option
Option A starts lemlist at full volume while lowering lemwarm. Option B raises lemlist by 5, 10 and 15 a day while lowering lemwarm, which the post calls more careful and harder to track.

What Lemwarm does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- Whether Lemwarm can send campaigns on its own
- Whether lemwarm can send any campaign mail by itself
- Whether lemlist's sequences check content before launch

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
You still need a sender
With Lemwarm you pair it with a sender, and lemlist is the one that includes it free. On Warmerly the sender is in the plan.
Two tools, two bills
Using Lemwarm with lemlist means two products working together, with one bill if your plan includes lemwarm. Using Warmerly alone means one product with one bill, and a sender that is not lemlist.
From warm-up to launch
Warmerly lets you launch on a young mailbox at 3 a day and climb. Lemwarm's route is to wait for a score above 90 and 14 stable days, then start lemlist at 30 and lemwarm at 10. The Warmerly route is faster, and the Lemwarm route is more cautious.
Branches and replies
If a lead opens but does not reply, the canvas can branch on opened, clicked, replied or timeout. lemlist's sequences are not covered by our reading of lemwarm's pages, so check lemlist's own.
Volume you can actually send
Five Starter mailboxes at 30 sends a day is about 150 a day, whatever the plan says, because there is no send quota. Lemlist's Email plan lists 50,000 emails a month, which is about 1,667 a day.
