Mapping Contact Fields During Import

Last Updated: Oct 6, 2025

Learn how to correctly map your contact information to the right fields in Sender for accurate data import.

What is Field Mapping?

Field mapping ensures that the data from your import file is placed in the correct fields in your Sender account. This process matches your file’s column headers with Sender’s contact fields.

Standard Contact Fields

Sender recognizes these standard fields automatically:

  • Email address (required)
  • First name
  • Last name

How Field Mapping Works

When you upload a file, Sender automatically detects and maps standard field names. Your first row should contain clear header names that match these fields.

Example of Proper Headers:

Adding Custom Fields

You can include additional information beyond standard fields:

  • Phone numbers
  • Company names
  • Job titles
  • Locations
  • Any other relevant data

Custom Field Format Example:

Tips for Successful Mapping

  • Use clear header names – Make column headers descriptive and easy to understand
  • Keep headers in the first row – Always place field names in row 1 of your file
  • Match standard field names – Use “Email address”, “First name”, and “Last name” exactly as shown
  • One header per column – Each column should have only one header name
  • No special characters in headers – Stick to letters, numbers, and spaces

Common Mapping Mistakes

Incorrect Header Names:

Incorrect: Email, E-mail, Mail
Correct: Email address

Incorrect: Name, Full name
Correct: First name, Last name

Missing Headers

Make sure your first row contains headers, not contact data, as shown in the examples in previous pointers.

Headers in Wrong Row

Headers must be in the first row of your file; otherwise, the file won’t be up to standards for our system to recognize all of your contacts.

Verifying Your Mapping

Before importing:

  • Open your file and check the first row
  • Confirm headers match Sender’s field names
  • Ensure all data aligns under the correct headers
  • Save your file and proceed with import

That’s it!
