In this guide we'll show you how to import contacts & contact lists. Understanding standard & custom fields is an essential part of this process, so if you're unfamiliar with how to manage your fields, please also view this tutorial: custom fields.
We highly recommend that you start every import by just importing a single contact out of the batch. This way, if there are any issues with your import, it's a tiny cleanup, rather than hundreds or thousands of contacts.
As always, we are happy to help - so don't hesitate to reach out to our support team with any questions.
