Why did FullEnrich find fewer work emails than usual?

What causes it?

1. Contacts sent without a LinkedIn profile URL can be matched less accurately, since including one improves matching.

2. FullEnrich checks the emails its data providers return and removes bad ones, so not every email a provider offers reaches your results.

3. A contact shows an invalid email only when no valid one was found for it, so more invalid results mean more contacts where nothing valid turned up.

How does FullEnrich work with Feder?

• Connect FullEnrich to Feder and it joins your Interest apps.
• When you connect FullEnrich, 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 FullEnrich, one of your Interest apps. Feder only reads. It never changes anything in FullEnrich.
