lemwarm
Builds under a 40 a day ceiling; about 4 weeks of warm-up then 2 more before campaigns on its home page, and about 40 days at an increment of 1 in its help centre.
The short answer
Warmup ramp and length, in one look.
Warmerly's ramp is published: 4 a day on day 0 to 50 a day by day 30, with Gmail held to 40 and Outlook to 30. Lemwarm builds volume under a 40 a day ceiling you set, with a ramp increment of 1 (about 40 days) or 2 (about 20 days), and says to allow about 4 weeks of warm-up plus 2 more before campaigns. Its own pages give different timings. Last checked 21 October 2026.

How Warmerly does it
Warmerly, in detail.
A fixed, published ramp over 30 days.
01
Anchor points
The daily quota moves between 4 a day at day 0, 8 at day 3, 15 at day 7, 25 at day 14, 35 at day 21 and 50 at day 30. It counts days the mailbox really sent.
Warmerly product, checked 21 October 2026
02
Provider caps
The quota is held to 40 a day on Gmail, 30 on Outlook and 25 on Zoho.
Warmerly product, checked 21 October 2026
03
Weekends and health cut it
Weekends run at 0.6 of the weekday quota, and a low health score or spam placement reduces it further.
Warmerly product, checked 21 October 2026
04
Linear between the anchors
The daily quota is worked out by straight-line steps between the anchor days, so day 10 sits between 15 on day 7 and 25 on day 14, rather than jumping a stage at a time.
Warmerly product, checked 21 October 2026
05
Days that really sent
The ramp counts days on which the mailbox sent at least one warmup email, not calendar age. A mailbox connected three months ago that never sent has not warmed up and starts low.

06
A mailbox graduates after 30 sending days
An hourly job moves a mailbox from ageing to active once it has 30 sending days, as long as warmup is on and it needs no reconnect. The label is a signal to you, since both states warm in the same way.
Warmerly product, checked 21 October 2026
07
Day-to-day jitter
Each day's quota moves up or down by up to about 15%, and sends are spread through the day by a random schedule, so volume is never a flat line.
Warmerly product, checked 21 October 2026
08
A local working window
Warmup sends happen between 08:00 and 20:00 in the mailbox's own time zone, because mail in the middle of the recipient's night is a strong bot signal.
Warmerly product, checked 21 October 2026
09
Weekends are quieter
Weekend days run at 60% of the weekday quota, worked out in the mailbox's own time zone.
Warmerly product, checked 21 October 2026
10
Health slows the ramp
A health score under 70 cuts the day's quota to 75%, under 50 cuts it to 40%, and a high spam placement score cuts it to 70% or 40%. The ramp recovers when the numbers do.
Warmerly product, checked 21 October 2026
11
The first email is immediate
A newly connected mailbox's first warmup email is planned for about a minute after connecting, whatever the local hour, and is read by its recipient after 10 to 20 minutes.
Warmerly product, checked 21 October 2026
12
Campaigns have their own start
A campaign whose mailboxes have had less than 14 days of warmup starts with a volume ramp of 3 emails per mailbox on day one. New mailboxes default to a daily campaign limit of 30.

Warmup runs on after launch
Warmup is not a setup step to finish. Keep it on after campaigns start, as the background activity that keeps the mailbox healthy.

How Lemwarm does it
Lemwarm, in detail.
A ramp you set yourself, under a ceiling, with timings that differ by page.
01
A 40 a day ceiling
A Lemwarm blog post says volume builds under a 40 emails/day ceiling, and most inboxes reach it in 3 to 4 weeks, then hold for 2 more weeks before campaigns.

02
Increment of 1 or 2
lemlist's help centre says an increment of 1 takes about 40 days to reach your target, and an increment of 2 about 20 days, which it says suits only an older mailbox. It keeps the increment at 1 for a new one.

03
About 4 weeks plus 2
The home page FAQ says about 4 weeks of warm-up, then 2 more weeks before you start real campaigns, and to leave lemwarm running afterwards.

A 4 to 6 week ramp
A second Lemwarm blog post says the ramp takes 4 to 6 weeks under the ceiling, then 1 to 3 weeks at 40 until the score is above 90.

Four steps in the dashboard
The blog says the dashboard walks you through four steps: choose your plan, connect your email provider, verify your email address and start lemwarm.

06
A new mailbox's target
lemlist's help centre sets the target for a new mailbox at 30 to 40 emails a day, with the warm-up value set to your target lemlist volume and lemlist itself kept at 0 while it warms.

07
Stabilisation is a rule
After the ramp the setup article requires 14 days at target with an inbox rate above 90%, and says spam in that window restarts the clock.

08
A short ramp after a pause
If a mailbox has been paused for more than 7 days, the article uses a short ramp with an increment of 3, and after serious damage restarts at about 15 a day of lemwarm and 15 of lemlist.

09
Launch volumes
At launch the article puts lemlist at 30 a day and lemwarm down to 10, moving lemlist to 40 a day after a month of clean sending, with total output under 70 a day per provider.

Older domains and new domains
A blog post says not to send anything from a new domain for the first four weeks, and to avoid starting new conversations from a new mailbox in week one by using answer-only mode.

Four phases
The same post describes ramp-up under a 40 a day ceiling, stabilisation until the score is above 90, a manual switch to lemlist campaigns, and a reputation checker keeping about 10 warm-up emails running.

Automatic switching is not live
The post says the switch from warm-up to campaigns is manual and automatic switching is coming later this year, so it is a promise and not a feature we count.

Weak mailboxes
If the health score falls below 80, the post says to use answer-only mode for a week, and if it does not recover within about four weeks to retire the mailbox and warm a new one.

What Lemwarm does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- A fixed daily schedule: Lemwarm leaves the target and increment to you
- How lemwarm chooses the day-to-day volume inside the ceiling
- Whether answer-only mode is a setting in the lemwarm dashboard or a lemlist feature
Where the sources disagree
We report each version rather than pick one.
- Ceiling: a Lemwarm blog post says 40 emails a day, while lemlist's help centre says total output stays under 70 a day per provider.
- Timing: its home page says about 4 weeks plus 2, a blog post says 4 to 6 weeks of ramp plus 1 to 3 weeks of hold, and its help centre says about 40 days at an increment of 1.
- Stabilisation: its blog says 1 to 3 weeks at 40 a day, while a later line in the same post says a week or two, and its help centre says 14 days.
The numbers
Only what we could verify.
| Measure | Warmerly | lemwarm |
|---|---|---|
| Warmup ramp and length | 4 a day on day 0 to 50 a day by day 30; Gmail held to 40, Outlook to 30. | Builds under a 40 a day ceiling; about 4 weeks of warm-up then 2 more before campaigns on its home page, and about 40 days at an increment of 1 in its help centre. |
| Daily warmup at day 0 | 4 | Set by you |
| Daily warmup at day 30 | 50 | Up to 40 |
| Days to full ramp | 30 | About 20 to 40 by increment |
| Quota on day 7 | 15 a day | Set by you |
| Quota on day 14 | 25 a day | Set by you |
| Quota on day 21 | 35 a day | Set by you |
| Weekend quota | 60% of a weekday | Not stated |
| Day-to-day jitter | About 15% | Not stated |
| Stabilisation before launch | No fixed period | 14 days at target, inbox rate above 90% |
| Total daily output guidance | Gmail 40, Outlook 30 for warmup | Under 70 a day per provider, all sources |
| Warm-up after launch | Keep on | 10 to 20 a day |
In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Set-and-forget against set-your-own
Warmerly's ramp needs no settings. Lemwarm's gives you control of the target and increment, which suits people who want it and adds a choice for people who do not.
Both advise keeping warmup on
Lemwarm says to leave it running after you start campaigns, at 10 to 20 a day.
Reading day 10
On Warmerly, day 10 of sending lands between 15 on day 7 and 25 on day 14, which is about 19 a day before jitter and weekends. On Lemwarm there is no matching figure, since the volume depends on the target and increment you set.
Two ways to arrive at 40 a day
Lemwarm's setup article reaches a 40 a day target in about 40 days at an increment of 1, or about 20 at 2. Warmerly passes 35 a day on day 21 and reaches the 40 a day Gmail cap in the days after, then continues towards 50 where the provider cap allows. The two are different designs, not a race.
A mailbox that only sends on some days
On Warmerly a mailbox that sends on 12 of its first 30 calendar days is on day 12 of the ramp, so about 22 a day, not 50. Lemwarm's pages do not say how pauses are counted.
When to start a campaign
Warmerly lets a campaign start on a young mailbox with a volume ramp of 3 a day. Lemwarm's guidance is to wait for a score above 90 and 14 stable days. Both are defensible, and a new domain may need longer on either.
Why jitter and weekends matter
A perfectly regular pattern is easy for a provider to spot. Lemwarm's blog says natural-looking engagement speeds things up and perfectly regular patterns backfire, and Warmerly's quieter weekends and daily jitter aim at the same thing.
Who it suits
Pick the one that fits.

- You want a ramp that slows itself when health drops
- You want a campaign to be able to start on a young mailbox with a small ramp

Lemwarm is the better fit if
- You want to set your own target and ramp increment

Questions
How long does warm-up take?
Warmerly's ramp reaches 50 a day on day 30. Lemwarm says about 4 weeks of warm-up then 2 more before campaigns, and its help centre gives about 40 days at an increment of 1. Neither promises a result in that time.
Is the ceiling the same?
No. Lemwarm's blog says a 40 a day ceiling, while its help centre says total output stays under 70 a day per provider. Warmerly holds Gmail to 40 and Outlook to 30 for warmup.
Can I speed up Warmerly's ramp?
Not past the published ramp. The daily limit setting on a mailbox does not skip it, because reputation is earned over days of sending.
Does Warmerly's ramp stop at weekends?
It runs at 60% of the weekday quota, based on the mailbox's own time zone, rather than stopping.
What if my score falls during the ramp?
On Warmerly a lower health score slows the day's quota, and a score under 60 for two days pauses the mailbox. Lemwarm's blog says to use answer-only mode for a week below 80 and to retire a mailbox that does not recover in about four weeks.
