Google Sheets to Lemlist, verified leads ready to send
You finally have a lead list. Then you spend the next hour cleaning names, hunting emails, second-guessing deliverability, and copy-pasting rows into your outreach tool.
This Sheets Lemlist leads automation hits growth marketers and SDRs first, honestly. But agency owners launching campaigns for clients feel the same drag. The outcome is simple: Google Sheets rows become verified, enriched leads inside Lemlist, ready to send.
Below, you’ll see exactly how the workflow turns raw spreadsheet data into campaign-ready contacts, what you need to run it, and where teams usually trip up.

The Problem: Lead lists look “ready” until they aren’t
A Google Sheet full of prospects feels like momentum, right up until you try to send. Some rows are missing emails. Some emails bounce. Names are inconsistently formatted, and half the “company” cells look like someone pasted a URL. Then you import into Lemlist, get errors, and end up manually fixing the same issues you fixed last week. The worst part is the mental load. You can’t confidently launch, because you do not trust the data.
It adds up fast. And the friction compounds as your list grows.
- Copying rows from Google Sheets into Lemlist forces you to double-check every field, which burns about an hour on even a small list.
- Unverified emails mean bounces, and bounces quietly damage deliverability for future sends.
- Enrichment gets skipped when you’re in a rush, so targeting stays generic and replies stay low.
- When you fix a row in Lemlist, the spreadsheet still stays messy, so the same errors come back on the next import.
The Solution: Verify and enrich in Dropcontact, then create Lemlist leads
This workflow takes the leads you already track in Google Sheets and turns them into campaign-ready contacts inside Lemlist. You trigger it in n8n, it pulls rows from your sheet, then sends each contact to Dropcontact to find a verified email and enrich the profile. Once Dropcontact returns the cleaned details, the workflow passes the finalized lead data to Lemlist and creates a lead directly in an existing campaign. No exporting CSVs. No reformatting headers. Just a straight line from “row in a sheet” to “lead ready to message.”
The flow starts with a manual run in n8n, which is perfect for batch imports and campaign launches. Google Sheets provides the raw lead rows. Dropcontact fills gaps and validates contact data. Finally, Lemlist receives the enriched lead and attaches it to the campaign you’ve already prepared.

Example: What This Looks Like
Say you’re launching a cold email campaign with 200 leads in Google Sheets. Manually, you might spend about 2 minutes per lead to check an email, enrich missing fields, and prep the import file, which is roughly 6–7 hours of busywork. With this workflow, the “work” is starting the run (about 2 minutes), then waiting while Dropcontact processes and Lemlist creates leads. You still review the final list, but that’s a quick scan, not a rebuild from scratch.
What You’ll Need
- n8n instance (try n8n Cloud free)
- Self-hosting option if you prefer (Hostinger works well)
- Google Sheets for storing your lead rows.
- Dropcontact to verify emails and enrich contacts.
- Lemlist to create leads inside an existing campaign.
- Dropcontact API key (get it from your Dropcontact dashboard).
Skill level: Beginner. You’ll connect accounts, map a few fields, and run a test with a small batch.

How It Works
Trigger the run from n8n. The workflow uses a manual start, so you can run it exactly when a list is ready (like right before a campaign launch).
Pull contacts from Google Sheets. n8n reads your spreadsheet rows and prepares each lead for processing, so the next steps receive consistent fields.
Verify and enrich with Dropcontact. Each contact is sent to Dropcontact to find a verified email and return enriched data you can use for personalization and filtering.
Create the lead in Lemlist. Once the contact data is clean, the workflow adds the lead directly to an existing Lemlist campaign so it’s ready for your sequences.
You can easily modify the Google Sheets column mapping to match your template, or switch the Lemlist destination to a different campaign based on your needs. See the full implementation guide below for customization options.
Step-by-Step Implementation Guide
Step 1: Configure the Manual Trigger
This workflow starts manually, which is ideal for testing your lead enrichment pipeline before scheduling or automating it.
- Add the Manual Execution Start node as the trigger.
- Keep all default settings, since this node has no parameters to configure.
- Connect Manual Execution Start to Update Google Sheet Data to follow the workflow execution flow.
Step 2: Connect Google Sheets
Pull raw lead data from a spreadsheet so it can be enriched and sent to Lemlist.
- Add the Update Google Sheet Data node.
- Set Range to
A:K. - Set Authentication to
oAuth2. - Enter your Sheet ID in sheetId.
- Credential Required: Connect your googleSheetsOAuth2Api credentials.
- Connect Update Google Sheet Data to Enrich Contact Details.
email or companyName, the enrichment step will fail.Step 3: Set Up Contact Enrichment
This step enriches each lead using Dropcontact based on fields from Google Sheets.
- Add the Enrich Contact Details node.
- Set Email to
={{$json["email"]}}. - In Options, set siren to
trueand language tofr. - In Additional Fields, map values: company to
={{$json["companyName"]}}, website to={{$json["website"]}}, linkedin to={{$json["LinkedIn"]}}, full_name to={{$json["fullName"]}}, last_name to={{$json["lastName"]}}, and first_name to={{$json["firstName"]}}. - Credential Required: Connect your dropcontactApi credentials.
- Connect Enrich Contact Details to Create Lemlist Lead.
Step 4: Configure Lead Creation in Lemlist
Send enriched lead data into your Lemlist campaign.
- Add the Create Lemlist Lead node.
- Set Resource to
lead. - Set Email to
={{$node["Enrich Contact Details"].json["email"][0]["email"]}}. - In Additional Fields, set lastName to
={{$node["Enrich Contact Details"].json["last_name"]}}, firstName to={{$node["Enrich Contact Details"].json["first_name"]}}, and companyName to={{$node["Enrich Contact Details"].json["company"]}}. - Enter your Lemlist campaignId to target the correct campaign.
- Credential Required: Connect your lemlistApi credentials.
Step 5: Test and Activate Your Workflow
Verify the end-to-end flow from Google Sheets to Dropcontact to Lemlist before enabling it in production.
- Click Execute Workflow to run Manual Execution Start manually.
- Confirm that Update Google Sheet Data outputs rows with the required fields like
emailandcompanyName. - Check that Enrich Contact Details returns enriched fields such as
first_nameandcompany. - Verify a new lead appears in Lemlist after Create Lemlist Lead runs successfully.
- When satisfied, switch the workflow to Active for production use.
Common Gotchas
- Google Sheets credentials can expire or need specific permissions. If things break, check the n8n credential connection status and the sheet’s sharing settings first.
- If you’re using Wait nodes or external rendering, processing times vary. Bump up the wait duration if downstream nodes fail on empty responses.
- Default prompts in AI nodes are generic. Add your brand voice early or you’ll be editing outputs forever.
Frequently Asked Questions
About 30 minutes if your accounts and sheet are ready.
No. You will connect Google Sheets, Dropcontact, and Lemlist, then map a few fields.
Yes. n8n has a free self-hosted option and a free trial on n8n Cloud. Cloud plans start at $20/month for higher volume. You’ll also need to factor in Dropcontact API usage costs based on how many leads you verify.
Two options: n8n Cloud (managed, easiest setup) or self-hosting on a VPS. For self-hosting, Hostinger VPS is affordable and handles n8n well. Self-hosting gives you unlimited executions but requires basic server management.
Yes, and it’s usually quick. Adjust the field mapping in the Google Sheets step, then update what you pass into Dropcontact (for example, first name, last name, company, and domain). On the Lemlist side, you can change the target campaign and map enriched fields into custom variables for personalization. A common tweak is adding an “If” check to skip rows that are missing a company name or look like duplicates.
Usually it’s an expired Google authorization or the sheet moved to a different Drive location. Reconnect your Google Sheets credential in n8n, then confirm the exact spreadsheet and worksheet are still selected. If the sheet is shared from another account, make sure your connected Google user still has access. Also check for renamed columns, because that can break field mapping silently.
Hundreds per run is normal, and larger batches work if you process them in chunks.
It depends on how picky you are about data quality and how often you run campaigns. n8n is strong when you want more control over field mapping, conditional logic, and batch handling without paying per tiny step. It’s also easier to keep the workflow as a repeatable “import process” you can tweak over time, instead of rebuilding zaps for each variation. Zapier or Make can be fine for a simple two-step sync, but verification and enrichment often turn into multi-step logic quickly. If you want a quick recommendation based on your volume and team setup, Talk to an automation expert.
Clean data makes outreach feel easy again. Set this up once, and your next campaign launch is mostly just pressing “run.”
