Why did my Wiza valid email count jump?

What causes it?

1. Refreshing a list has Wiza look up its contacts again for the latest data, so an older list can gain emails on the day it is refreshed.

   In the Wiza help: Refreshing a list will have Wiza head to the profiles of your contacts, and find the freshest data possible. How do I refresh my list? | Wiza Help Center, read 2026-11-12.

2. A refresh can be aimed at just the contacts whose emails were risky or not found, so it looks again where no valid email was found before.

   In the Wiza help: Refresh all contacts, or choose specific contacts with risky or unfound emails, missing phone numbers, or missing personal emails. How do I refresh my list? | Wiza Help Center, read 2026-11-12.

3. Wiza verifies emails in real time, so whether an address counts as valid reflects its state when Wiza checks it.

How do I check it myself?

1. If you are the admin of a team account, look at each user's activity over the days around the jump to see whose work drove it.

   In the Wiza help: You also have the flexibility to examine a user's activity over different time frames, up to a maximum of 90 days. How do I keep track of how my team is using Wiza? | Wiza Help Center, read 2026-11-12.

2. Filter your contacts by list to see which list the new valid emails belong to.

How does Wiza work with Feder?

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