Fix contact import issues

Having trouble importing your contacts? Here are common issues and how to fix them.

Common Import Problems

File Format Issues

Problem: File won’t upload or shows an error

Solution:

  • Verify your file is in a supported format: CSV, TXT, or XLSX
  • Check that your file size is under 64MB
  • Try converting your file to a different supported format and importing again

Missing or Incorrect Headers

Problem: Contacts import without names or data appears in wrong fields

Solution:

  • Ensure the first row contains column headers
  • Use standard header names: Email address, First name, Last name
  • Check that headers match your data columns

Email Address Errors

Problem: Some contacts fail to import

Solution:

  • Verify all email addresses are properly formatted (example@domain.com)
  • Remove any spaces before or after email addresses
  • Check for missing @ symbols or domain extensions

Empty Rows or Columns

Problem: Import fails or shows unexpected results

Solution:

  • Delete any empty rows between contacts
  • Remove blank columns from your file
  • Ensure data starts from row 2 (row 1 being headers)
