Workaround available Web Updated November 13, 2026Based on 2 user reportsHow we research

Quick answer

A malformed row halts the whole import; add correctly named header rows (Email address, First name) and map columns. Counts can be lower than your file because duplicates are never added twice.

Most likely fix: Fix the file

How to fix it

Try these in order — the most common fix is first.

  1. 1. Fix the file

    1. Add header rows named to match Kit's fields such as Email address and First name
    2. Check for malformed rows and re-save as CSV
    Did this fix it?

  2. 2. Understand the count

    1. Addresses already in Kit are not added again, so the increase may be lower than rows in your file
    Did this fix it?

  3. 3. Avoid overwriting data

    1. Imports replace existing data with blank values if your file has blank fields; split large imports or drop empty columns
    Did this fix it?

Symptoms

Import errors out, says no email address column, or shows fewer subscribers than your CSV.

Why it happens

  • Malformed row stops the importer
  • Missing or misnamed headers
  • Duplicates already on the list
