How Warmerly does it
Warmerly, in detail.
One warmup on every plan, with no personalised tier.
01
Same warmup on every plan
Every mailbox follows the same ramp and pairing rules on every plan. Plans differ in mailbox count and allowances, not in how warmup works.
Warmerly product, checked 21 October 2026
02
No template warm-up
Warmup mail is between mailboxes in the pool. Warmerly does not warm up your own campaign templates.

03
No industry-tailored network
We do not publish a network tailored to your industry.

04
Message content has rules
Warmup content comes from a corpus with merge fields limited to first name, day of week and topic, and with no links and no promotional wording. It is the same on every plan.

05
A pre-launch content check instead
Before a campaign starts, a warning fires if the spam-word score is 25 or more, a subject shouts or repeats punctuation, or the email has more than 5 links or 3 images. It warns and does not block.

06
Warnings need your yes
A campaign with warnings is refused once until you resend with the warnings acknowledged, so a quality risk is accepted knowingly.

07
AI openers are separate
An AI opener step uses AI credits, 100 a month on Starter, 500 on Growth and 2,500 on Agency, and needs a campaign brief.

08
Placement tests cover the rest
A placement test sends one message to up to four targets and scores where it lands, which tests the mailbox rather than a template.

A questionnaire sets it up
lemlist's help centre says Smart uses a questionnaire to adapt warm-up content and cluster, and that Smart suits you if you want more customised warm-up emails, including custom variables.

What Lemwarm does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- The size of the industry-tailored network
- The spam rate threshold at which a template is paused
- The spam rate at which a template is paused
- How the questionnaire maps to a cluster
- Whether template warm-up counts towards the daily ceiling

Per month. Lemwarm prices are per email address and were read on lemwarm.com/pricing on 21 October 2026; the yearly figures are shown when its Yearly option is selected. Warmerly's email plans cover mailboxes and its LinkedIn add-on is charged per account on top. A lemlist plan that includes lemwarm changes the comparison.
In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Do you need it?
Smart is aimed at teams that want to test their own copy before sending. Warmerly's campaign pre-launch checks warn about spam-style copy, which is a different tool for a similar worry.
Doing the arithmetic
Moving 10 mailboxes from Essential to Smart adds 10 x $20 = $200 a month at monthly prices. That is a lot more than Warmerly Starter's $19 for 5 mailboxes, so Smart only makes sense if template testing changes your results.
What you would test
If you run one cold intro to 2,000 prospects, a template that hits spam costs you that campaign. Template warm-up tries to find that out for 3 to 7 days first. Warmerly's check catches the obvious causes, such as too many links, but does not send the template anywhere.
An honest limit on both
A template warmed inside a network is judged by network mailboxes, not your prospects. Neither product can promise that a template that passes will land for your list.
Who it suits

Questions
Does Warmerly have anything like Smart?
Not for warmup. Warmerly's warmup is the same on every plan. Its campaign pre-launch check warns about spam-style copy, but it does not warm your templates.
Is Smart worth $49 a mailbox?
That depends on how much you rely on template testing. The pricing page gives no figures on results, so we cannot say what it is worth.
Does Warmerly pre-test my templates?
It checks them before launch for spam-style words, shouting, links and images, and warns. It does not warm your templates inside the network.
Does Lemwarm Essential include anything like that?
Essential includes a content email, a DNS check and the Warmup Score. Template warm-up and the industry cluster are Smart features.
How much does Smart cost for 10 mailboxes?
$490 a month at $49 each, or $400 a month on the yearly option at $40 each.
