TL;DR
– Lemlist is the best choice for email-first outreach with rich personalization and lemwarm, but LinkedIn is a secondary channel available only on Expert plans.
– PhantomBuster is a data extraction and list-building tool, not a sequencer — it requires a separate email platform to run actual outreach.
– La Growth Machine is the only tool where LinkedIn + email are both native from the entry plan, with waterfall enrichment, Voice Messages AI, and Social Warming built in.
– If you want a single multichannel outreach platform with no stack complexity, LGM wins on depth and total cost of ownership.

We Tested All Three for 90 Days — Here Is What We Found
The market for B2B outreach tooling is crowded with options that, on the surface, claim to do similar things. But after spending 90 days running real campaigns through lemlist, PhantomBuster, and La Growth Machine, one thing became clear: these tools are built on fundamentally different philosophies.
Lemlist is an email-first multichannel platform with LinkedIn available as an add-on on its Expert plan. It has earned a strong reputation for deliverability infrastructure and image/video personalization. PhantomBuster is a web scraping and automation tool built around “Phantoms” — individual automation scripts for LinkedIn extraction and basic sequences. It is excellent at building prospecting lists, but it is not a sequencer. La Growth Machine runs LinkedIn and email natively from its Basic plan, with waterfall enrichment, Voice Messages AI, and Social Warming built in. We tested all three for 90 days across list building, outreach sequencing, deliverability, and total cost of ownership.
Round 1: Core Architecture
Understanding why these tools behave the way they do starts with architecture.
Lemlist: Email-first with multichannel added on
Lemlist was built as a cold email platform. Its Email Pro plan (~$59/month) gives you email sequences, lemwarm (their native email warmup system), strong deliverability infrastructure, and one of the best personalization engines on the market — including liquid syntax for dynamic images and videos in emails. LinkedIn automation was introduced later and is only available on the Multichannel Expert plan (~$99/month). If you want to run LinkedIn + email from the same tool, you have to step up to Expert. The result is a polished email product with LinkedIn bolted on.
PhantomBuster: Script-based automation platform
PhantomBuster is fundamentally different from the other two. It is not a sequencer at all. It is a platform built around individual automation scripts called “Phantoms” — each one performing a discrete task: scraping a LinkedIn profile, extracting connections, sending connection requests, building lists from Sales Navigator. You can chain Phantoms into “Flows,” but the tool has no conditional logic, no reply detection, no InMail management, and no native email sending. Pricing starts at ~$59/month (Starter) and ~$139/month (Pro). It is a powerful data extraction layer, not an outreach engine.
La Growth Machine: Native multichannel from day one
La Growth Machine was designed around the premise that LinkedIn and email are equally important channels — so both are available from the Basic plan (€60/month per identity). There is no “add LinkedIn later” pricing trap. Built-in waterfall enrichment finds professional email addresses across multiple providers sequentially, so you do not need to subscribe to a separate enrichment tool. Voice Messages AI, Social Warming, and Real Chat Mode are also included at various plan levels. The cloud-based infrastructure means campaigns run 24/7 without keeping a browser open.
Round 2: LinkedIn Depth
LinkedIn depth is where the three tools diverge most dramatically.
PhantomBuster: Strong extraction, weak sequencing
PhantomBuster excels at LinkedIn data extraction. You can scrape Sales Navigator search results, extract post likers, pull profile data from LinkedIn groups, and build comprehensive lead lists at scale. For list-building operations, it is genuinely powerful. The problem starts when you try to use that data in sequences. PhantomBuster has no conditional logic (if no reply, then…), no InMail management, no pre-warming sequences, and no native email follow-up. It can send connection requests and basic LinkedIn messages through its Phantoms, but calling this a “LinkedIn sequence” is generous. You will invariably need a second tool to actually run outreach on the leads PhantomBuster builds.
Lemlist: LinkedIn as a secondary channel
Lemlist’s LinkedIn capabilities are solid but constrained by their late arrival to the platform. On the Multichannel Expert plan, you can add LinkedIn steps — profile visits, connection requests, LinkedIn messages — alongside your email sequences. The integration works, but it is clearly designed as a complement to email, not an equal channel. There is no Social Warming, no Voice Messages AI, no LinkedIn Intents, and no pre-connection warm-up logic comparable to what LGM offers.
La Growth Machine: LinkedIn as a native channel
LGM’s LinkedIn capabilities are the deepest of the three. Social Warming automatically visits profiles, likes posts, and follows prospects before the first outreach touch — increasing connection acceptance rates significantly in our tests. LinkedIn Intents (Pro plan) lets you import leads directly from intent signals: people who follow your company, viewed your profile, attended a LinkedIn event, or engaged with content. Voice Messages AI (unique to LGM) lets you send AI-generated personalized audio messages on LinkedIn — a format with dramatically higher open and response rates than text. Real Chat Mode mimics human typing speed and patterns to reduce LinkedIn flag risk. Conditional workflows mean every sequence branch is handled: if connected, if replied, if email not found.
Round 3: Email Deliverability and Sequences
Lemlist: Email is where it shines
This is lemlist’s home territory, and it shows. lemwarm is one of the most mature email warmup systems available — it automatically exchanges emails with other lemwarm users to build sender reputation before and during campaigns. The email personalization engine is class-leading: you can embed custom images with dynamic text overlays, personalized videos, and Liquid syntax variables that go far beyond {{first_name}}. Deliverability-focused features like smart sending, inbox rotation, and bounce shields are baked into the platform. If cold email is your primary channel, lemlist is a serious contender.
PhantomBuster: No email sequences whatsoever
PhantomBuster does not have email sequences. Full stop. It can scrape email addresses from LinkedIn profiles (with limited accuracy) and export them to a CSV, but the actual sending of emails is outside its scope entirely. If you use PhantomBuster as your lead generation engine, you will need to route those leads into a separate email tool — adding cost, workflow complexity, and data synchronization overhead.
La Growth Machine: Native email with waterfall enrichment
LGM’s email sequences are tightly integrated with its LinkedIn sequences. The waterfall enrichment system is a key differentiator: when a prospect’s professional email is not found in the first enrichment provider, LGM automatically cascades through additional providers to maximize coverage — all without a separate subscription or manual export/import. Inbox rotation prevents any single mailbox from overloading. Native email is available from the Basic plan, meaning your first euro spent on LGM gives you both channels simultaneously.
Round 4: Pricing and Real Total Cost of Ownership
Sticker prices rarely tell the full story in B2B SaaS. Here is what each tool actually costs when you account for the full stack needed to run outreach at scale.
Lemlist Multichannel Expert: ~$128/month
The Multichannel Expert plan at ~$99/month gives you LinkedIn + email + lemwarm. But you still need enrichment to find email addresses for LinkedIn prospects. Adding a mid-tier enrichment tool (Apollo, Hunter, or similar) runs ~$29/month minimum. All-in: approximately $128/month per user. lemwarm is included, which saves the cost of a separate warmup tool.
PhantomBuster Pro: ~$176/month or more
PhantomBuster Pro at ~$139/month gives you data extraction at scale. But you need a separate email sequencing tool (~$37/month for a basic plan on Instantly, Smartlead, or similar) and enrichment is only partially covered by PhantomBuster’s scraping (accuracy is lower than dedicated enrichment providers). A more realistic estimate for a complete stack built around PhantomBuster is $176-$220/month — and that stack is also more complex to operate, with data moving between multiple tools.
La Growth Machine Basic: €60/month all-in
LGM Basic at €60/month per identity includes LinkedIn automation, email sequences, Social Warming, Voice Messages AI, and waterfall enrichment. There is no enrichment add-on to purchase, no warmup tool to subscribe to, and no email platform to integrate. Pro (€120/month) adds LinkedIn Intents, Real Chat Mode, and A/B Testing. Ultimate (€180/month) adds Twitter/X outreach and native HubSpot/Pipedrive CRM sync. The total cost of ownership for LGM is structurally lower because the tool is designed to replace the stack, not join it.
Verdict: Which Tool for Which Use Case?
| Use case | Best tool | Why |
|---|---|---|
| Email-first outreach with rich personalization | Lemlist | Best-in-class email personalization, lemwarm, deliverability tooling |
| LinkedIn data extraction and list building | PhantomBuster | Purpose-built for scraping Sales Navigator, profiles, and LinkedIn data at scale |
| Native LinkedIn + email multichannel sequences | La Growth Machine | Both channels from Basic, conditional logic, Social Warming |
| Full outreach stack in a single platform | La Growth Machine | Enrichment, warming, LinkedIn, email, voice — no third-party tools needed |
| PhantomBuster as a data layer feeding LGM | PhantomBuster + LGM | Build lists with PhantomBuster, run sequences in LGM — a complementary stack |
The most important reframe for PhantomBuster: it is not competing with LGM or lemlist as a sequence tool. It is competing with Sales Navigator exports and scraping tools. Many advanced LGM users actually combine the two — using PhantomBuster to build hyper-targeted lead lists (post likers, event attendees, competitor followers) and importing those lists into LGM to run the actual outreach sequences.
Lemlist is the right answer if cold email deliverability and email personalization are your primary obsessions, and you use LinkedIn as a secondary touch. It is not the right answer if LinkedIn is your primary channel.
LGM is the right answer if you want both channels at full depth from day one, without building and maintaining a multi-tool stack.
FAQ
Is PhantomBuster a good alternative to La Growth Machine?
Not as a direct alternative. PhantomBuster is a data extraction and list-building tool — it does not have email sequences, conditional logic, reply detection, or warmup features. It can complement LGM as a prospecting layer (build lists with PhantomBuster, sequence in LGM), but it cannot replace a sequencing platform. If you need a single tool to run LinkedIn + email outreach from end to end, LGM is the right choice.
Does lemlist have LinkedIn automation on all plans?
No. LinkedIn automation in lemlist is only available on the Multichannel Expert plan (~$99/month). The Email Pro plan (~$59/month) covers email only. If you want LinkedIn + email in lemlist, you need to be on the highest standard tier.
What is waterfall enrichment and does lemlist or PhantomBuster have it?
Waterfall enrichment is the process of cascading through multiple email enrichment providers sequentially until a valid professional email address is found. La Growth Machine has it built in natively. Lemlist does not include enrichment — you need a third-party tool. PhantomBuster can scrape email addresses from LinkedIn profiles, but this is not the same as waterfall enrichment through professional enrichment databases, and accuracy is significantly lower.
What is Voice Messages AI in La Growth Machine?
Voice Messages AI is a feature unique to La Growth Machine that generates personalized AI voice messages sent directly on LinkedIn. Because voice messages on LinkedIn have dramatically higher open rates than text messages, they function as a high-response-rate touch point in an outreach sequence. Neither lemlist nor PhantomBuster offers anything comparable.
Can I use PhantomBuster and La Growth Machine together?
Yes — and this is actually a recommended workflow for power users. Use PhantomBuster to build hyper-targeted lead lists from LinkedIn sources (post engagers, event attendees, LinkedIn group members, Sales Navigator searches), export to CSV, and import into LGM to run the actual sequences. This combines PhantomBuster’s scraping depth with LGM’s sequencing sophistication.
How does La Growth Machine pricing compare to lemlist for a team of 3?
For a team of 3 identities: LGM Basic costs €180/month total (3 × €60), covering LinkedIn, email, waterfall enrichment, Social Warming, and Voice Messages AI. Lemlist Multichannel Expert for 3 seats runs ~$297/month (3 × $99), plus enrichment costs (~$87/month). LGM is meaningfully cheaper for multichannel teams while also providing deeper LinkedIn capabilities and eliminating the need for a separate enrichment subscription.
