Do you want to learn how to add contacts to your Mailchimp Audience? In this tutorial I describe the three ways of adding contacts to an Audience (add one-by-one, integrate with external tools and import from Microsoft Excel, Google Sheets or CSV files). In addition I show how to copy-and-paste into your Audience from Google Sheets and Microsoft Excel.
These instructions have been designed to be of benefit to beginners as well as those that are familiar with Mailchimp.
Once your contacts are in Mailchimp then get your contacts to keep their own details up-to-date.
