Yes! You can upload your own .CSV file, which should at least contain the following fields: affiliate first name, affiliate last name, affiliate email, and (optionally) affiliate password. You can also import additional fields such as address or company details (more options will follow).
First go to your affiliates overview page. Click on "New Affiliate".
This will generate a pop-up where you can choose between two options: Either manually add your affiliates through a form, or import a .CSV document. Click on "Add through .CSV".
On the next page you can upload your actual affiliate .CSV file. A thumbs up will appear if you've successfully uploaded your file.
The next page shows how your document is set up. Remember to check the "First row contains column headers" box, if that applies. You can also make alterations to the headers by clicking on the down-pointing arrow.
After you've set your columns and rows you'll have to choose to which program you want to add these affiliates. If you want to send your new affiliates a welcome email containing their temporary password, toggle on the box.
If you're all set, the last step is to confirm your upload. Your affiliates will appear within approximately 5 min.
