Can I import custom variables when uploading CSV files?
Last updated: June 5, 2026
Context
When importing CSV files into lists, you may want to include custom variables that are specific to your CRM system, such as language learned by contacts or other custom fields that help segment your data.
Answer
Currently, importing custom variables directly through CSV uploads is not supported.
For Company Data (inclusion and exclusion)
When importing company CSV files, you only need these minimum required columns:
company_name(required)company_url(required)company_linkedin_url(optional but recommended)
For Contact Lists (inclusion and exclusion)
When importing contact CSV files, email addresses are the required field, though including additional contact information will improve the exclusion accuracy.
However, there is an effective workaround to achieve similar segmentation results.
Recommended Workaround
Create separate lists for each custom variable value. For example, if you want to track "language learned" by contacts:
Create multiple sequences:
Language learned → English
Language learned → German
Language learned → Spanish
Prepare separate CSV files for each sequence based on your custom variable values
Import each CSV into its corresponding sequence
Benefits of this approach:
Easier comparison of results based on your custom variables
Better performance tracking across different segments
Clear separation of data for analysis purposes
