Why did my Cyberimpact contact count drop?
The Cyberimpact help pages give 4 common reasons. The first to rule out: Deleting contacts while working in one group removes them from every other group they were in too.
Is it broken, or just quiet?
A number can fall because fewer people came, or because something stopped counting them. Below are the causes the Cyberimpact help pages give, and how to check each one yourself.
What causes it?

How does Cyberimpact work with Feder?
- Connect Cyberimpact to Feder and it joins your Reach apps.
- When you connect Cyberimpact, Feder checks the connection straight away and shows Connected only when that check passes. If a reading cannot be taken later, Feder shows it as not read, never as zero.
Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.
See whether you can trust the numbers in Cyberimpact, one of your Reach apps. Feder only reads. It never changes anything in Cyberimpact.
