Importing your customer lists to Vainu

First, create an Excel file with business IDs (not available in the US database), domains or official registered names of the companies you want to import. Make sure your file does not contain unnecessary sheets/tabs. If you have more than 20 000 companies in your list, you might want to consider splitting the file into two separate files.

❗️Note that Business IDs are highly recommended. To get the best possible match with Vainu's database, company names have to correspond to the name in the official company register.


Here’s how you can import a list of companies to a list.

1. Start by clicking on the list icon on left panel.

3. Wait for the upload process to finish. After the import has finished you will see the imported companies on your static list. If the companies don't appear after the upload has finished, please refresh the page. Be patient! Uploading companies will take time. You can use Vainu normally when the upload process is on going.

After upload is complete your prospect list opens in front of you. You can find it later from Lists section on left panel.
