Switching from La Growth Machine to lemlist: How to Do It Right

Why teams switch from La Growth Machine to lemlist

La Growth Machine covers LinkedIn, email, X, and calls, but has no SMS and no WhatsApp, which means mobile-first touchpoints sit outside your outreach entirely. That gap alone pushes teams to look for a broader platform once their outbound motion matures beyond email and LinkedIn.

LGM also has no native lead database. You need to find prospects elsewhere (LinkedIn, CSV) before importing them, which adds friction to the workflow. If you want to source leads and run outreach in one place, that friction compounds quickly.

Here is what typically drives the switch:

• •

  Channel coverage: LGM’s LinkedIn features run deeper, but lemlist spreads development effort across more channels, including WhatsApp, which La Growth Machine does not support natively.

• •

  Lead sourcing: lemlist includes a 600M+ B2B contact database with filters for tech stack, funding, hiring trends, and revenue. LGM requires you to bring leads from an outside source.

• •

  Deliverability infrastructure: lemlist includes lemwarm and a deliverability hub. LGM lists inbox rotation but no warm-up, which makes scaling email volume riskier over time.

• •

  Intent signals: lemlist can detect high-intent events (funding rounds, job changes, hiring shifts, website visits) and auto-enroll matching leads into campaigns. LGM has no equivalent.

What to audit in La Growth Machine before you export anything

Before you touch the export button, walk through your LGM account and inventory everything worth keeping. Skipping this step is how data gets lost mid-migration.

Lead lists and audience segments

Note which audiences are active, which are paused, and which hold historical value you still care about. Write down any custom filters or segmentation logic you applied in LGM so you can rebuild them later.

Active and paused campaigns

Document each campaign’s status, channel mix, step count, and current performance. Flag campaigns still generating replies so you can wind them down gracefully rather than cutting them off mid-sequence.

Enrichment data and custom variables

List every custom variable you created in LGM (icebreakers, company-specific fields, personalization tokens). Note which fields came from manual entry versus enrichment, because that distinction tells you what to re-enrich after import.

CRM sync settings and logged activity

LGM can automatically synchronize interactions in your CRM, including native integrations with HubSpot and Pipedrive. Record your current sync rules, field mappings, and lifecycle stage triggers. This prevents gaps when you reconnect your CRM to lemlist.

How to export your leads and campaign data from La Growth Machine

LGM lets you export most data to CSV, but the process is split across several screens. Here is the sequence to follow.

1. Export audiences to CSV from the Leads tab

Go to the Leads tab, click Import Leads (which also houses the export), and select your audience. Map out the fields you want to export. You can export all leads at once or filter by audience first. This is the most important step because your contact data is the hardest thing to recreate.

2. Export campaign-level data

Pull opens, clicks, replies, and connection-accepted data per campaign. LGM lets you export campaign and lead data anytime, or pull it into your dashboards via API and Zapier. This history helps you benchmark performance in lemlist after the switch.

3. Download CRM activity logs

If CRM sync was active, export a backup of all LGM-originated activities from HubSpot or Pipedrive. Those activities stay in your CRM regardless, but a backup ensures your pipeline history is independent of LGM access.

4. Screenshot your sequence workflows

LGM’s visual workflow builder doesn’t export to a portable format. Screenshot each sequence’s branching logic, delays, and channel steps so you can rebuild them accurately. This takes ten minutes per campaign and saves hours of guesswork later.

How to set up your lemlist account for a clean start

Handle infrastructure first. Your account has to be warm and ready before any leads arrive, and this step is the most commonly skipped part of onboarding.

1. Connect your sending domains and mailboxes

Add your dedicated sending domains (separate from your main company domain) and connect mailboxes. lemlist handles DNS authentication automatically during setup, so the technical lift here is minimal.

2. Activate lemwarm and the Deliverability Hub

Start warmup immediately, even before importing leads. lemwarm builds sender reputation by exchanging real emails with real inboxes at a controlled pace. The Deliverability Hub monitors inbox placement across Google, Microsoft, and other providers so you can catch problems before they affect reply rates.

3. Connect your CRM

Set up your HubSpot or Salesforce sync so new lemlist activity flows into your CRM from day one. Map lifecycle stages, deal triggers, and contact ownership before launching any campaigns. Doing this after you have live campaigns running creates gaps in your reporting.

4. Set up your LinkedIn account

Connect your LinkedIn account to enable automated profile visits, connection requests, messages, and voice notes. lemlist uses smart delays and human-like behavior patterns to protect your account from LinkedIn restrictions.

How to import your La Growth Machine data into lemlist

With infrastructure in place, it is time to bring your lead data over.

1. Clean and format your CSV files

Remove duplicate rows, normalize column headers, and strip emoji or special characters from names and job titles. lemlist needs Row 1 to contain column names only and Row 2 onward for lead data, with one lead per row (see lemlist's CSV import guide). If your first row contains an actual email address, lemlist treats it as a column name and skips that lead.

2. Map LGM fields to lemlist variables

During the “Set up imported custom variables” step, assign each CSV column to the correct lemlist variable type. This is what makes lemlist recognize fields like {{email}} and {{linkedinUrl}} in your campaign steps (see lemlist's guide to choosing the right CSV import type). Any LGM fields that don’t have a direct equivalent (like custom icebreakers) can be stored as custom variables.

3. Run enrichment to fill gaps and verify contacts

Use lemlist’s waterfall enrichment to re-verify emails and find missing phone numbers. Contact data goes stale quickly, and records that were valid in LGM three months ago may have bounced since then. On the “Enrich leads data” step, choose whether you want lemlist to find or verify emails, find phone numbers, or enrich LinkedIn data, then click Import leads to finish.

How to rebuild your multichannel sequences in lemlist

Rebuilding is faster than starting from scratch because you already know what worked. Focus on replicating your proven LGM sequences first, then expand.

Recreating your email and LinkedIn sequences

Use your screenshots from the audit step to rebuild each LGM workflow in lemlist’s sequence builder. If you want to speed this up, lemAgent (lemlist’s AI campaign assistant) can generate a full multichannel sequence from a plain-language description of your goal and ICP. You describe what you want, and it builds the steps, timing, and branching logic.

Adding channels LGM did not support

This is where the switch pays off. Insert SMS steps after missed calls, add WhatsApp messages to reduce no-shows before meetings, and use the built-in dialer for call steps triggered by email engagement. These are channels you simply couldn’t run inside LGM.

Using conditional logic and engagement-based triggers

lemlist lets you branch sequences based on specific lead behavior: opened email, clicked a link, accepted a LinkedIn connection, replied on any channel. This is more granular than LGM’s if/else branching because each condition can route the lead to a different channel or message, not just a different delay.

Capabilities you gain after the switch

Beyond replacing what LGM offered, lemlist adds layers that had no equivalent in your old stack.

• •

  Built-in lead database with ICP filters: Search 600M+ contacts and 65M+ companies by tech stack, funding, revenue, growth, and hiring trends. You no longer need a separate prospecting tool to build lists.

• •

  Intent signals that trigger campaigns automatically: lemlist’s Intent Signal Agents detect events like funding rounds, job changes, and website visits, then auto-enroll matching leads into sequences with messaging personalized to that exact moment.

• •

  AI agentic enrichment: AI agents pull structured context from websites, LinkedIn profiles, CRM records, and sales call recordings (via Claap), then convert that context into ready-to-use personalization variables and qualification scores.

• •

  Inbox placement testing: The Deliverability Hub can test whether your emails land in primary, promotions, or spam across Google and Microsoft before a campaign goes live. That visibility alone can prevent weeks of wasted sends.

Common mistakes that stall the migration

• •

  Sending campaigns before warming up mailboxes: Your new mailboxes have no reputation yet. Sending cold campaigns from day one is the fastest way to land in spam.

• •

  Skipping data cleanup: Outdated emails, duplicate contacts, and broken formatting carry over from LGM and inflate bounce rates in lemlist.

• •

  Rebuilding every old campaign at once: Start with the two or four sequences that drove the most replies and meetings. Migrate the rest once those are running.

• •

  Cutting LGM access too early: Some teams lose access before downloading CRM logs or workflow screenshots. Keep your LGM subscription active through the transition.

• •

  Not re-verifying contact data: People change jobs, emails go invalid. Run enrichment on imported lists to catch what your original LGM enrichment missed.

Your week-by-week migration timeline

A realistic migration takes about four weeks if you run warmup in parallel with data prep.

Week 1: audit and export

Inventory LGM audiences, campaigns, and CRM settings. Export all leads and campaign data to CSV. Screenshot workflows. Wind down active campaigns that are finishing their sequences.

Week 2: lemlist setup and warmup

Connect domains, activate lemwarm, set up CRM sync, and connect LinkedIn. Warmup runs in the background while you prep data. Start onboarding your team to lemlist’s interface.

Week 3: import, rebuild, and test

Import cleaned CSVs, map variables, run enrichment. Rebuild your top-performing sequences. Send test campaigns to internal addresses to verify deliverability and formatting before going live.

Week 4: launch and decommission LGM

Launch rebuilt campaigns in lemlist. Monitor early results in the Deliverability Hub. Once all active leads are migrated and no replies are expected in LGM, cancel your LGM subscription.

Over to you

Switching from La Growth Machine to lemlist is a structured process, not a one-click migration. The prep work you do in weeks one and two determines how smoothly campaigns perform in weeks three and four. Take the time to audit, clean, and warm up properly, and the transition becomes a straight line rather than a scramble.
