Main job, in one look.

How Warmerly does it
Warmerly, in detail.
Warmerly's main job is email: warm a mailbox over 30 days, keep its DNS and blocklist status checked, then send cold email sequences from it. LinkedIn is a paid add-on that plugs into the same sequences.
01
It starts with the mailbox
Warmup mail between real mailboxes ramps from 4 a day on day 0 to 50 a day on day 30, with lower ceilings for Gmail (40), Outlook (30) and Zoho (25). A mailbox only does campaign work on top of that ramp.

02
Then campaigns and sequences
A sequence is made of email steps, wait steps, LinkedIn connection and message steps, and condition steps that branch on opened, clicked, replied or timeout. A campaign sends at most 30 emails a day from a mailbox by default and runs pre-launch checks before it starts (13 kinds are listed in the code).

03
DNS and blocklists are watched
SPF, DKIM, DMARC and MX are checked every six hours for each mailbox, with a written fix when one fails. Sixteen blocklists are checked on the same schedule.

04
LinkedIn is an add-on, not the core
Each connected LinkedIn account is $19 a month, charged at once with no trial and no refund. Packs are 3 accounts for $49 and 5 for $75. It runs through a hosted provider (LinkupAPI), and a customer can connect an account because the production switch was on when we read it on 15 October 2026.

05
Where Warmerly is narrower on LinkedIn
Warmerly's LinkedIn sequence steps are a connection request and a message. We found no step that visits a profile, follows, endorses or sends an InMail, and no signal that adds people from profile or company visits. Its LinkedIn depends on one hosted provider.

06
Sending stops by itself when bounces rise
The reputation job pauses sending at a 7 per cent bounce rate or a 30 per cent undeliverable rate, each after at least 25 sends. Pre-launch checks cover 13 kinds of issue before a campaign starts, and a mailbox sends at most 30 a day by default.

Warmup is on the free plan
Warmup is not metered and is included on every plan including Free, so the first job, getting a mailbox ready, costs nothing extra.

How La Growth Machine does it
La Growth Machine, in detail.
La Growth Machine describes itself as LinkedIn and email in one sequence, with calls and, on Ultimate, X. It prices per identity, a seat that automates outreach.
01
One sequence across channels
Its multichannel page says a sequence can start on LinkedIn and move a lead to email if an invite is not accepted after a few days, or start on email. A reply on any channel stops the sequence for that lead by default.

02
The channels it lists
The features index and sequence builder list LinkedIn steps, email from your own mailbox, call tasks with your script, and X steps (follow, unfollow, favourite, retweet, tweet). Its pricing page puts calls on Pro and X on Ultimate.

03
Data and AI around the sequence
The home page lists a B2B database with enrichment, intent signals, a shared inbox, and AI workflows that work from Claude or ChatGPT.

04
Safety is part of the pitch
Its deliverability page says LinkedIn runs in the cloud on a dedicated mobile proxy for each identity, with limits and working hours set per identity.
lagrowthmachine.com/features/deliverability · read 21 October 2026
05
Its own reach claims
Its pages say 10,000 or more teams run outreach on it, 20 million or more LinkedIn invitations were sent from the cloud, and 400,000 or more emails go out each month. They are its statements, we cannot check them, and they carry no date beyond the August 2026 label on one.

06
A claim about both channels together
The same page says a median contact rate of 79.2 per cent for LinkedIn plus email campaigns, against 20.6 per cent for LinkedIn only, from its own campaigns in August 2026. We did not check it and it is not a Warmerly result.

07
Seats are identities, mailboxes sit inside them
Basic allows 1 sending address per identity, Pro 5 and Ultimate 10. Reaching 25 addresses therefore takes 5 Pro identities or 3 Ultimate ones.

08
Email is not the whole sequence
Its inbox rotation page frames email as one channel: a bounce stops email for that lead and LinkedIn steps carry on, and an If Bounced condition can route the lead to LinkedIn.

What La Growth Machine does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- A feature that warms a mailbox: its deliverability page says warm-up is not built in
- A stated schedule for how a new LinkedIn account should ramp
- A date for when its reach figures were last updated
- A number of mailboxes that are warmed by the product itself
Where the sources disagree
We report each version rather than pick one.
- The home-page copy and the pricing page describe the channels slightly differently: the pricing page lists LinkedIn and email on Basic, adds calls on Pro and X on Ultimate.

Only what we could verify.

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
They overlap on sequences, little else
Both build a sequence with LinkedIn and email steps. La Growth Machine goes wider on channels and data. Warmerly goes deeper on the mailbox behind the email.
Warming is left to you on its side
La Growth Machine's own pages tell you to warm a new mailbox with another service before adding it to a campaign, so the two tools can sit side by side.
Twenty-five mailboxes, two ways
On the dollar price table billed monthly, 25 sending addresses cost 5 Pro identities at $135, which is $675, or 3 Ultimate identities at $195, which is $585 for 30 addresses. Warmerly's Growth plan is $49 a month for 25 mailboxes with warmup and DNS checks. The comparison is not like for like: identities also run LinkedIn, calls, an inbox and enrichment credits, and Warmerly's mailboxes do not.
One prospect, two lanes
A prospect can get a LinkedIn connection request from La Growth Machine on day 0 and an email from a warmed Warmerly mailbox on day 1, with each tool running its own lane. The sample fortnight on the main page shows it. A reply on either lane has to be seen in that tool's own inbox.
What the choice usually turns on
If your meetings come from LinkedIn, an identity is the unit you will pay for, and Warmerly's LinkedIn add-on is the lighter option. If they come from cold email, the mailbox count and its warmup are the unit, and La Growth Machine leaves warming to another tool.
Who it suits
Pick the one that fits.
Warmerly
Warmerly is the better fit if
- Cold email is your main channel and the mailbox needs warming and watching
- You want a flat price per plan, not per seat
- You want LinkedIn as a light add-on to email
- You send from many mailboxes and want one price for the lot
La Growth Machine
La Growth Machine is the better fit if
- You want LinkedIn, email, calls and X in one sequence
- You want data, enrichment and a shared inbox in the same product
- You are comfortable warming mailboxes with another tool
- Your meetings come mainly from LinkedIn and you want calls in the same flow
Questions
Does La Growth Machine include X?
Its sequence builder lists X steps, and its pricing page puts X on the Ultimate plan. Warmerly has no X channel.
Which is cheaper for 25 mailboxes?
Warmerly Growth is $49 a month for 25 mailboxes. On La Growth Machine, 25 sending addresses need 5 Pro or 3 Ultimate identities, $675 or $585 billed monthly. They do different jobs, so the totals are not like for like.
Can I use both?
Yes. Warm and watch the mailboxes in Warmerly, then connect them to La Growth Machine as sending addresses, and keep LinkedIn sequences there.
Does Warmerly replace La Growth Machine?
Only for email. It has no calls, X steps or enrichment waterfall.
