To export influencer you first need to create a list of the accounts you would like to export.
Next up, go to "Influencer lists" tab on the navigation bar on the left side of your screen and open your list.
Click "Export CSV" button on the right side of your screen. Clicking this opens a small popup that, if you're allowed to process details like contact information, allows you to export CSV with contact details included.
If it's appropriate for you to be exporting contact details for your campaigns or GDPR doesn't apply in your region or to your influencers, click "it's okay, I'm allowed to process details like contact info".
Now that you've exported your file, you will find influencer contact details in your file.
