✅ How to Format Your CSV File

Formatting your CSV correctly is the first step to a successful import. Here’s what to do:

  • Your file can include as many columns as you want.

  • The first row must contain column names (e.g., email, firstname, city).

  • Avoid spaces in column names, especially for URLs.

💡 Pro Tip: Download this CSV template to use as a guide for formatting your files.


✅ How to Import Leads from a CSV File

Follow these steps to import leads into lemlist:

1. Go to the Leads List

In your campaign, navigate to the Leads List section and select "Import from CSV."

2. Upload Your CSV

  • Browse your computer or drag and drop your .CSV file.

  • Click Continue to proceed.

3. Map Your Variables

  • Each column name becomes a custom variable. lemlist automatically maps common fields like email, firstname, and lastname.

  • For unrecognized columns, manually map them or create Custom Variables for unique data (e.g., City, Blog).

💡 Best Practices for Mapping Variables:

  • Use lemlist’s default variables when possible: email, firstname, lastname, etc.

  • Ensure URLs don’t have spaces in their column names.

  • Include as many custom variables as needed for personalization.

These are lemlist default variables:

  • email

  • firstname

  • lastname

  • picture

  • phone

  • linkedinUrl

  • companyName

  • companyDomain

  • icebreaker

4. Set Import Preferences

  • Choose to skip leads already in other campaigns.

  • Select enrichment options for additional data insights.


✅ How to Fix CSV Import Issues

If your CSV won’t upload, check the following:

🔹 Browser Compatibility: Use Chrome or another updated browser instead of Safari.
🔹 File Format: Ensure your file is a pure .CSV and not an Excel CSV. Convert if necessary.
🔹 Emails Are Required: Every row must have an email address, as it serves as the unique ID in lemlist.
🔹 Field Matching: Map your CSV fields to the appropriate lemlist variables.


FAQs for Smooth Imports

1. Can I use custom variables?

Yes! Add unique data for personalization (e.g., blog URLs or company info). lemlist supports unlimited custom variables.

2. What’s the best way to avoid import errors?

  • Use the CSV template as a guide.

  • Test your import with a small file first.

3. Why isn’t my CSV importing?

  • Double-check the format: pure .CSV only.

  • Ensure column names match lemlist variables.

  • Verify your browser and file compatibility.


Pro Tips for Efficient CSV Imports

💡 Ensure the first row in your file contains column names.
💡 Use meaningful names for custom variables to simplify mapping.
