CSV upload is the fastest way to bring an existing lead list into Vosen. You drop in a file, tell Vosen which column maps to which field, and Vosen immediately generates a personalised voice note script for every row — all before a single message is sent.

​

Uploading your CSV

1

Open your campaign

Navigate to Campaigns in the left sidebar and click the campaign you want to add leads to. If you haven’t created one yet, click New campaign first.
2

Click "Add leads" → "Upload CSV"

Inside the campaign, click the Add leads button and select Upload CSV from the dropdown menu.
3

Select your file

Drag your CSV file onto the upload area or click Browse to find it on your computer. Vosen accepts .csv files up to 10 MB.
4

Map columns to fields

Vosen displays a column-mapping screen. Use the dropdowns to match each column in your file to the correct Vosen field. Columns Vosen can’t auto-detect are highlighted for your attention. Click Confirm mapping when done.
5

Preview personalised scripts

Vosen generates an AI-written script for every lead using the data you’ve mapped. Scroll through the previews, edit any script inline, and mark individual leads as approved or skipped.
6

Confirm and continue

Click Add to campaign to finalise the import. Your leads are now queued and ready to send when you launch the campaign.

​
Script personalisation

Vosen’s AI uses the data from your CSV to write a unique, emotion-enhanced script for each lead. Here’s how the fields are used:
  • First Name — Vosen opens the voice note by addressing the lead directly, making it feel like a real conversation starter.
  • Company — Vosen weaves the lead’s employer into the message to show you’ve done your homework (“I noticed you’re at Acme Corp…”).
  • Job Title — Vosen tailors the value proposition to the lead’s seniority and function (“As a Head of Growth, you’ll appreciate…”).
When all three personalisation fields are present, the result is a script that sounds hand-crafted — not templated.
Always include Company and Job Title in your CSV. Even one extra field significantly increases the relevance of the generated script and lifts reply rates.
LinkedIn URLs must be the full profile URL in the format https://linkedin.com/in/username. Short URLs, vanity redirects, or Sales Navigator links will cause the lead to fail validation and be excluded from the campaign.
