Heyreach vs La Growth Machine: Which Cold Outreach Tool Is Superior?

I priced out a five-person outbound team on all three tools this month. Two of them bill you per seat. One does not.

HeyReach is a LinkedIn automation platform built for agencies running many LinkedIn accounts at once. La Growth Machine is a French multi-channel tool that puts LinkedIn, email, calls and X into one visual sequence builder.

Salesforge sits in the same category but sells the layer underneath as well: infrastructure, warm-up, lead data and an autonomous AI SDR. UniteSync ran that combination to an 85.26% positive reply rate at a $2.86 cost per acquisition, and the case study is public.

Multichannel Outreach Comparison at a Glance: HeyReach vs La Growth Machine

HeyReach Overview: LinkedIn Outreach Priced per Sender

HeyReach is a LinkedIn automation platform aimed at agencies, sales teams and GTM operators. Its pitch is sender rotation: connect many LinkedIn accounts and spread outreach volume across all of them.

The company reports 6,500+ customers and a 4.7 rating on G2. I go deeper in this HeyReach review.

Core features:

• Sender rotation across accounts - one campaign draws from a pool of connected LinkedIn accounts, keeping each within daily limits.
• All native LinkedIn actions - connection requests, messages, follows and profile views, with an "If Connected" condition to split existing contacts from new ones.
• Unified Inbox - LinkedIn conversations from every connected account land in one dashboard.
• Multichannel through partners - email steps run through native Instantly and Smartlead integrations, not inside HeyReach.
• Enrichment credits - 100 per sender on HeyReach Growth, 1,000 on Agency, 3,000 on Unlimited, as one-time allocations.
• Workspaces and permissions - client data, senders and campaigns stay separated under one login.
• API, webhooks, MCP server and CLI - available on every tier, including the entry plan.
• Whitelabel - one branded instance included on Agency; multi-brand whitelabels cost $500 per add-on on Unlimited.

Pricing from the live HeyReach pricing page: HeyReach Growth is $79 per sender per month, dropping to $71 per seat quarterly and $63 per seat yearly. HeyReach Agency is $999/month for 25 senders, or $799/month billed yearly. HeyReach Unlimited is $2,999/month, or $2,399/month billed yearly.

A Done-for-you tier is quoted by sales.

Worth flagging: several comparison blogs currently list HeyReach Growth at $59 per seat and an unlimited tier at $199. Neither figure appears on the live pricing page, so budget from the vendor's own numbers.

HeyReach fits agencies managing 10 or more client LinkedIn accounts. The per-sender model charges for LinkedIn accounts rather than people, so adding VAs, clients or teammates to the dashboard costs nothing extra. That is a real advantage over per-user tools when a small team operates many profiles.

What reviewers say about HeyReach

Support speed is the recurring complaint. A two-star Trustpilot review from November 2025 describes waits of 24 to 48 hours on urgent tickets, some tickets never answered, and MCP data that did not match the main dashboard. Independent reviews of HeyReach report the same 1 to 2 day average response time.

Honest limitations:

• No email sending of its own. Running email and LinkedIn together means a second subscription and a second set of campaign data.
• No warm-up product and no email infrastructure, so deliverability sits entirely outside the tool.
• Sender rotation, the reason to pick HeyReach, does nothing until a second LinkedIn account is connected.
• No AI SDR option, which is the axis I break down in Salesforge vs HeyReach.
• HeyReach Agency and Unlimited require you to bring your own proxies; only HeyReach Growth includes a dedicated residential proxy per sender.

La Growth Machine Overview: Four Channels, Per-Identity Billing

La Growth Machine is a Paris-based multi-channel outreach platform that says it has safely automated LinkedIn since 2017. It runs LinkedIn, email, calls and X inside one visual sequence, and reports 10,000+ GTM teams on the product. Support is handled in-house from France.

Core features:

• Multi-channel sequences with conditions - branching on connection accepted, message replied, email opened, profile visited back and more.
• LinkedIn voice messages - AI-generated voice notes sent in sequence, a channel few competitors automate.
• Waterfall email enrichment - 9 email providers and 2 verification tools queried in sequence, plus a 27M+ company database.
• Rotating inbox - 1 sending email per identity on Basic, 5 on LGM Pro, 10 on LGM Ultimate.
• Multichannel Inbox - LinkedIn and email replies grouped by lead, from LGM Pro upward.
• Intent data import - pull post likers, commenters and event attendees straight into campaigns.
• CRM sync - native HubSpot and Pipedrive two-way sync, LGM Ultimate only; other CRMs go through Zapier.
• Account safety - fully cloud-based with dedicated 5G mobile proxies and smart sending limits.

Pricing from the live La Growth Machine pricing page, per identity per month: LGM Basic €60 monthly and €50 annual; LGM Pro €120 monthly and €100 annual; LGM Ultimate €180 monthly and €150 annual. Quarterly sits between at €57, €114 and €171. An Agency tier needs six identities minimum, and a Custom tier starts at €150 with a six-month commitment.

One correction: several directories still list LGM Ultimate at €120, matching LGM Pro. The live page prices it at €180 monthly, in euros.

La Growth Machine fits EU-based solo operators and small teams that genuinely use more than two channels. If X outreach or LinkedIn voice notes are core to how you sell, it does things the other two cannot.

What reviewers say about La Growth Machine

Reliability at scale is the theme. A one-star Trustpilot review from May 2026 documents a team that bought 20 identities and spent close to $10,000. Their list of faults includes webhooks delivered late or ten times over, a hard ceiling of five inboxes per identity, LinkedIn replies silently dropped, and campaign progress lost on edit.

A separate two-star review from June 2026, titled "Not reliable", lists the same three complaints: expensive, poor support, many bugs. Octopus CRM put LGM's Trustpilot average at 3.3 out of 5 in May 2026, well below its G2 and Capterra scores. I track sentiment further in these La Growth Machine reviews.

Honest limitations:

• Enrichment is capped at 250, 400 or 1,000 leads per identity per month. Past the cap you buy credits, at 5 credits per fully enriched lead.
• No native email warm-up, so a new sending domain needs a separate warm-up tool before campaigns start.
• The Multichannel Inbox, custom sequences, A/B testing and API all sit above LGM Basic.
• LGM Basic caps you at 3 identities and 3 running campaigns.
• No AI SDR and no infrastructure layer, covered in Salesforge vs LGM.

Salesforge Overview: The Outreach Layer of the Forge Stack

Salesforge is an all-in-one cold outreach platform that runs email and LinkedIn as two channels of one workflow. It was founded in 2023 by Frank Sondors, Dovydas Volodko and Daniel Sanchez, is used by 10,000+ businesses, holds a 4.6 rating on G2, and is SOC 2 compliant.

Core features:

• Conditional multi-channel sequences - LinkedIn and email steps branch on real prospect behaviour inside a single sequence.
• Six native LinkedIn actions - connection requests, messages, InMails, post likes, follows and withdraw requests, covered in this LinkedIn outreach guide.
• Unlimited mailboxes on every plan - connect as many sending accounts as your infrastructure supports.
• Unlimited LinkedIn senders and unlimited users on Salesforge Growth, replacing per-seat billing entirely.
• Free unlimited Warmforge warm-up - premium pool by default, with Heat Score™ per mailbox and placement tests.
• Primebox™ unified inbox - email and LinkedIn replies in one view with AI sentiment tagging, free on every plan.
• Overdrive Mode personalization - AI drafts from prospect website, blog posts and LinkedIn activity across 21+ languages.
• Smart mailbox rotation and dynamic IPs - sending spread automatically across connected mailboxes.
• ESP Matching - sender provider matched to recipient provider on Salesforge Growth.
• Unlimited workspaces - one per client or project, which is how agencies run the platform.
• Native CRM integrations - HubSpot, Salesforce, Pipedrive, Attio, folk, Breakcold, GoHighLevel, plus Clay and Zapier.
• API, MCP server and a unified CLI - the MCP server lets Claude or Cursor build sequences directly.

The wider context matters here. Salesforge is the outreach layer of the Forge Stack.

Underneath it sit Mailforge at $3 to $2 per mailbox, Infraforge with dedicated IPs at $4 to $3, and Primeforge for real Google and Microsoft mailboxes at $4.50 to $3.50. Warmforge handles deliverability and Leadsforge supplies 500M+ contacts.

Neither competitor sells any of these layers.

Pricing: Salesforge Pro is $48/month billed monthly, or $40/month billed annually. Salesforge Growth is $96/month billed monthly, or $80/month billed annually, and adds unlimited users, unlimited LinkedIn senders, A/B testing, multi-language sequences, the API, ESP Matching and Primebox AI.

Agent Frank, the AI SDR, is a separate subscription from $499/month billed quarterly, or $416/month billed annually. He is not bundled into either plan.

Annual rates reflect two months free, and you can verify the live price before buying.

Salesforge fits B2B teams selling at $5K to $100K ACV into startups, SMBs and mid-market, with 3,000 or more target accounts. Agencies use the unlimited-workspace model to run many clients from one login.

Honest limitations:

• Email infrastructure is not included in any plan. You connect your own mailboxes or buy Mailforge, Infraforge or Primeforge separately.
• Salesforge Pro is capped at 1 user and 1 LinkedIn sender, so teams start on Salesforge Growth.
• Agent Frank requires a sales demo plus a two-week warm-up, with no self-serve trial.
• Salesforge publishes its own anti-ICP: it says it is a poor fit for Fortune 500 procurement, long RFP cycles and six-figure bespoke deals.

Head-to-Head Feature Comparison: HeyReach vs La Growth Machine

Multi-channel outreach: one sequence or two tools

HeyReach automates LinkedIn only. Email steps run through its native Instantly and Smartlead integrations, which means a second subscription, a second campaign builder and split reporting. La Growth Machine genuinely runs four channels in one sequence, and adds LinkedIn voice notes plus X, which Salesforge does not.

Salesforge runs email and LinkedIn with six native LinkedIn actions in one conditional sequence, with phone on the roadmap.

For a two-channel motion, one sequence beats two synced tools. I ranked the wider category in this roundup of LinkedIn automation tools. I cover the wider category in this guide to multichannel outreach.

Email deliverability and warm-up

HeyReach has nothing to compare here, because it sends no email at all. La Growth Machine does send email, but it ships no warm-up product.

Its answer is the rotating inbox. That spreads volume across 5 or 10 addresses per identity, which helps, but it does not build sender reputation on a cold domain.

Warmforge is included free and unlimited with every Salesforge subscription. Its pool is premium by default, blending aged IMAP/SMTP, Google Workspace and Microsoft 365 mailboxes, with multilingual warm-up traffic and a Heat Score™ per mailbox where 97+ signals healthy.

Salesforge publishes hard thresholds too: bounce rate under 1%, pause immediately above 5%. Its free deliverability tools test SPF, DKIM and DMARC before you send. More detail sits in this breakdown of cold email deliverability.

AI personalization and the AI SDR question

HeyReach relies on integrations such as Clay for personalization depth. La Growth Machine includes an AI writing assistant on every plan and AI-generated voice messages, which is a genuine edge for LinkedIn-first sellers.

Salesforge personalizes from prospect website, blog posts and LinkedIn activity, in 21+ languages, with Overdrive Mode pulling every source at once.

Neither competitor offers an autonomous AI SDR. Agent Frank prospects, writes, follows up, handles replies and books meetings across both channels, running in Auto-Pilot or Co-Pilot. VAI Consulting booked three calls in a single week with him.

Inbox management and reply handling

HeyReach's Unified Inbox consolidates LinkedIn messages across connected accounts, which solves real pain for agencies, but email replies live in whichever email tool you bolted on. La Growth Machine's Multichannel Inbox does group LinkedIn and email by lead, though it starts at LGM Pro rather than LGM Basic.

Primebox™ unified inbox is free on every Salesforge plan. It unifies email and LinkedIn, tags sentiment automatically, and catches replies sent from an address you never contacted. AI-drafted replies require Salesforge Growth.

Pricing and scalability

Both competitors bill per unit of sending capacity. HeyReach charges per LinkedIn sender; La Growth Machine charges per identity. Add a rep and the bill rises in both.

Salesforge Growth is flat at $96/month monthly or $80/month annual, with unlimited users, unlimited LinkedIn senders and unlimited mailboxes. Five reps cost the same as one. That is the structural difference, and the Trustpilot reviewer who bought 20 LGM identities for roughly $10,000 is the clearest illustration of what per-seat billing does at scale.

Email infrastructure options

Neither HeyReach nor La Growth Machine sells mailboxes or domains. You buy infrastructure elsewhere and connect it, and when a domain burns you handle the replacement yourself.

Salesforge offers three infrastructure products under one login, and recommends mixing two for risk diversification. Woodpecker scaled to 2,500+ mailboxes on Infraforge. Salesforge also publishes its volume maths: 30 to 50 cold emails per mailbox per day, 2 to 5 mailboxes per domain, so roughly 20 to 30 mailboxes across 5 to 10 domains to send 1,000 emails a day.

Lead data and enrichment

HeyReach grants a one-time 100 enrichment credits per sender on its HeyReach Growth plan. La Growth Machine includes 250 to 1,000 enriched leads per identity monthly plus waterfall enrichment across 9 providers, which is the better bundled data offer of the two, though campaigns stall when the cap is hit.

Leadsforge searches 500M+ contacts from a chat prompt, pulls competitor followers and company lookalikes, and pushes lists straight into Salesforge sequences with no CSV step. It is a separate subscription at $49/month, with 100 free credits to start.

Integrations, API and compliance

HeyReach deserves credit for putting its API, webhooks and MCP server on every tier, including the $79 entry plan. La Growth Machine syncs natively only with HubSpot and Pipedrive, and only on LGM Ultimate; its API starts at LGM Pro.

Salesforge integrates natively with seven CRMs, gates its API and full integrations library to Salesforge Growth, and is SOC 2 compliant. Neither competitor advertises SOC 2 on its site, though La Growth Machine does publish a GDPR data processing agreement. Salesforge also ships an MCP server and a single CLI covering all six Forge products.

On account safety all three take it seriously. La Growth Machine is fully cloud-based with dedicated 5G mobile proxies, and HeyReach Growth includes a residential proxy per sender. Salesforge applies smart mailbox rotation and dynamic IP rotation on every plan.

Pricing Comparison: What It Costs to Scale a Team

The pattern is straightforward. HeyReach and La Growth Machine charge for each sender you add, so the bill grows with the team. Salesforge charges for the workspace, so adding people costs nothing.

Here is the scenario I ran. Five reps, email plus LinkedIn, annual billing.

Salesforge Growth costs $80/month, covering all five users, five LinkedIn senders and unlimited mailboxes, with warm-up and Primebox™ included. HeyReach Growth costs 5 × $63, so $315/month, and that buys LinkedIn only, with an Instantly or Smartlead subscription still to add. LGM Pro costs 5 × €100, so €500/month, capped at 400 enriched leads per identity and with no warm-up layer.

One cost the tables hide: HeyReach Agency and Unlimited require you to supply your own proxies, so budget for those separately.

Add infrastructure to make the comparison fair. Twenty Mailforge mailboxes run about $60/month on top of Salesforge, and the same mailboxes would be needed under either competitor. Note that La Growth Machine bills in euros, so convert at your own rate before comparing line items.

Who Should Use Which Tool for Multichannel Outreach

Here is how I would split the three, based on how each one is actually built. More side-by-side tool comparisons sit in the comparison library.

You might consider HeyReach if:

• Your outbound is LinkedIn-only and you already run email in Instantly or Smartlead, since HeyReach integrates natively with both.
• You are an agency operating 25 or more client LinkedIn accounts, where HeyReach Agency at $999/month for 25 senders beats per-seat maths and includes whitelabel.
• You need API, webhook and MCP access on an entry-level plan rather than a top tier.

You might consider La Growth Machine if:

• X outreach or LinkedIn voice messages are core to your motion. It automates both, and Salesforge does not.
• You are an EU team of one to three identities that wants bundled enrichment and French-based support, and can absorb per-identity pricing at that size.

Choose Salesforge if:

• You sell B2B at $5K to $100K ACV into SMB or mid-market and work a list of 3,000+ target accounts.
• You want email and LinkedIn in one conditional sequence, with replies from both channels in Primebox™.
• Your team is growing and you refuse to pay more per head. Salesforge Growth covers unlimited users and unlimited LinkedIn senders at $80/month annual.
• You run an agency and need a separate workspace, isolated infrastructure and dedicated IPs per client.
• You want the option of an AI SDR later. Agent Frank runs the whole motion on a separate subscription from $499/month billed quarterly.

Final Verdict: Which Outreach Platform to Choose

HeyReach and La Growth Machine each solve a narrower problem than their marketing implies. HeyReach automates LinkedIn well, but it has to borrow another product to send an email. La Growth Machine is a real four-channel tool, but its per-identity billing and missing warm-up layer both get expensive once outbound starts working.

Neither sells mailboxes, neither warms a domain, and neither has an AI SDR.

For multi-channel B2B outbound that needs to survive team growth, Salesforge is the stronger choice. At $80/month for Salesforge Growth billed annually, you get unlimited users, unlimited LinkedIn senders, unlimited mailboxes, free unlimited Warmforge warm-up and Primebox™ - a combination neither alternative sells at any price.

One falsifiable benchmark to hold me to: UniteSync ran Salesforge with Mailforge and Warmforge to an 85.26% positive reply rate at a $2.86 cost per acquisition, and ChannelCrawler hit 85.71% positive replies on Salesforge with Infraforge and Warmforge. Both case studies are published with names attached.

If your outbound stays LinkedIn-only, a dedicated LinkedIn tool is the cheaper pick. Most teams I talk to add email within a quarter, and per-seat pricing stops making sense there.

Frequently Asked Questions

For multi-channel outbound, yes. Salesforge runs email and LinkedIn in one conditional sequence, includes free unlimited Warmforge warm-up and Primebox™, and sells three email infrastructure products. HeyReach automates LinkedIn only and needs Instantly or Smartlead for email. La Growth Machine covers four channels but bills per identity and ships no warm-up. For LinkedIn-only agencies running 25+ client accounts, HeyReach Agency at $999/month is the better-fitting economics.

Pricing structure. Salesforge charges per workspace, so Salesforge Growth at $80/month annual covers unlimited users and unlimited LinkedIn senders. HeyReach charges $79 per LinkedIn sender per month. La Growth Machine charges €60 to €180 per identity per month. The second difference is depth: Salesforge sells the infrastructure and deliverability layers underneath outreach, and neither competitor sells either.

Salesforge, once more than one person sends. A single seat is closest on HeyReach Growth at $63/month yearly versus Salesforge Pro at $40/month annual. At five senders on annual billing, Salesforge Growth is $80/month total, HeyReach Growth is $315/month for LinkedIn only, and LGM Pro is €500/month. Salesforge does not charge per user, so the gap widens with every rep added.

Not natively. HeyReach automates LinkedIn actions only, and email steps run through its native Instantly and Smartlead integrations. That means a second subscription, a second sequence builder and campaign data split across two tools. HeyReach also sells no warm-up product and no email infrastructure, so deliverability sits entirely outside the platform. Salesforge runs both channels in one sequence with warm-up included free.

No. La Growth Machine has no native warm-up product. Its deliverability answer is the rotating inbox, which spreads sending across 5 addresses per identity on LGM Pro and 10 on LGM Ultimate. Spreading volume is useful, but it does not build reputation on a cold domain. Every Salesforge subscription includes unlimited premium Warmforge warm-up with Heat Score™ monitoring at no extra cost.

Salesforge, because deliverability is a product rather than a setting. Warmforge warms every mailbox from a premium pool of aged IMAP/SMTP, Google Workspace and Microsoft 365 accounts, runs DNS and blacklist health checks, and scores each mailbox 0 to 100 with 97+ as healthy. It also sells Mailforge, Infraforge and Primeforge. HeyReach sends no email at all, and La Growth Machine relies on inbox rotation alone.

Yes. Contacts import by CSV or Google Sheets connection, and mailbox connections are unlimited on every plan, so you can connect existing Google Workspace or Microsoft 365 accounts straight away. Warm-up starts during the 14-day free trial. The step people underestimate is deliverability: run a Warmforge placement test on each mailbox before launching, and keep warm-up on permanently rather than cycling it.

Yes, 14 days with no credit card required. The trial includes 50 contacts, 100 emails, 50 email validation credits, 50 personalization credits and 100 social action credits, plus unlimited mailbox connections and warm-up. Agent Frank is the exception: he needs a sales demo and a two-week warm-up period, and has no self-serve trial. HeyReach offers 14 days with 3 LinkedIn accounts; La Growth Machine offers 14 days with 1 identity.

Agencies and GTM teams running many LinkedIn accounts at once. Sender rotation only activates from the second connected account, so solo operators miss the main advantage while paying $79/month. HeyReach Agency covers 25 senders for $999/month with whitelabel included, which undercuts per-seat LinkedIn tools at that volume. The trade-offs reviewers raise most often are support response times of 24 to 48 hours and the absence of any email channel.
