Address Mapping

Getting Started

When uploading an address list to create a mailing in LetterStream, you’ll be guided through a address mapping process. This step ensures the system correctly interprets the information in each column of your file.

How Column Mapping Works

After uploading your CSV address list, you’ll arrive at a column mapping screen. Here, you identify what each column in your file represents, such as:

  • First Name
  • Last Name
  • Address Line 1
  • Address Line 2
  • City
  • State
  • Zip Code

Each column must be matched with the correct data type to ensure successful mailing.


Automatic vs. Manual Mapping

If your CSV column headers are clearly labeled (e.g., "FirstName", "Address1", "City"), LetterStream will try to automatically match them to the correct fields.

However, if a column is unclear or labeled differently (e.g., "State" instead of "ST"), the system might not map it correctly. In such cases, you will need to manually select the appropriate field.


Adjusting Mappings Manually

To make manual adjustments:

  1. Locate the dropdown menu next to the column in question.
  2. Click the dropdown and choose the correct field (e.g., "State").
  3. Repeat this for any column the system did not auto-map correctly.
