Sure:
1. There is a big drop. The developer had to remove one of his apps due to issues that are not connected to us (or advertising). That's the reason for the drop. Just to remind anyone's who's reading this, cause it became such an important issue lately -
appnext is 100% Google complient.
2. US traffic made about 70%-75% of the revenue.
3. The send by email function is very simple - it's just another option to engage with the ad, but later. User doesn't have to fill out his email - it's already there.
See example attachd.
