Adding a test influencer is easy. We will simply find an existing real influencer, add them to My Influencers and then set a unique contact email address to one we control (but not our main email address).
We must use a different email address because we can only log in to dyzio from one browser at a time.
Find an influencer. I will use Zoella.
Add the influencer to My Influencers, using your own email address.
You can now add this test influencer to your campaigns and send an invitation to them. Remember to use a different email address to your main one. Also remember YOU MUST log in using a different browser, i.e. one browser for your main login and one browser for your new test influencer.
