How to Import Contacts/ Upload List?

Our import subscriber lists feature allows you to add a list of contacts to Mail250. You can also use this feature to auto-update multiple existing contacts at once.

To get started, you’ll need a blank sheet in a spreadsheet program like Microsoft Excel or Google Sheets, saved or exported as a comma separated value (CSV) file.

Import New Contacts / Upload List

There are a few different ways to import contacts to Mail250, but a file upload is the most common method. The file import process has two parts: First, you’ll prepare your spreadsheet of contacts outside of Mail250, and save it as a CSV file. Next, you’ll use our import tool to add your contacts to Mai250.

  1. In a spreadsheet program like Excel or Google Sheets, open your blank worksheet.
  2. Create and label a column for EMAILEmail upload
