Follow these steps to add contacts to the subscribers area of your Email Marketing account.
If you would like to add just a single contact, you can use either tab. In the One by one tab you can add the email and name details into special fields for that data. And in the Many at a time tab, you can simply paste the details into the Paste contacts field.
If you are on the One by one tab, the window doesn't close automatically. This is so you can easily add another contact. To close the window, just click the X.
