One of them I did it on the wrong way (I picked random e-mail addresses from the csv-list and not the first mailaddress).

1. I did not see a way to delete a test.
2. I did it 2 days ago, but still the dashboard shows: your remaininging email tests: 8.
When it is renewed every day it should show 10 (I have tier 1 - 10 test every day)
Now it looks I have 10 test a week or month or....
3. To see the total results of a test, there is a small button at the right of an email test 'View'. It took me some time to find this. This important button may be more vissible.
