Why did my contact growth drop in Quentn?
The Quentn help pages give 3 common reasons. The first to rule out: Contact growth is new contacts minus those lost to unsubscribes and bounces, so a wave of bounces can pull growth down even when sign-ups hold steady.
What causes it?
Contact growth is new contacts minus those lost to unsubscribes and bounces, so a wave of bounces can pull growth down even when sign-ups hold steady.
In the Quentn help:
minus the contacts lost due to subscription cancellations or bounces
The Dashboard, read 2026-11-12.Contacts whose emails bounce are blocked automatically to protect deliverability, so they stop counting as reachable.
In the Quentn help:
Bounced contacts are automatically blocked by Quentn
The Dashboard, read 2026-11-12.An address that is blocked for a short time five times becomes blocked for good, so repeated soft bounces can remove a contact.
In the Quentn help:
After five temporary blocks, the email address will be permanently blocked.

How do I check it myself?
Filter contacts by when a tag was added to see whether new contacts are still arriving through a given form or source.
In the Quentn help:
Searches for all contacts who have been assigned a specific tag at a defined time or before or after.
Contact filter, read 2026-11-12.When filtering by activity in a period, remember that contacts created during that period are left out, so the result can look smaller than the list.
In the Quentn help:
Please note that only contacts that already existed in the entire period are taken into account!

How does Quentn work with Feder?
- Connect Quentn to Feder and it joins your Interest apps.
- When you connect Quentn, 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 Quentn, one of your Interest apps. Feder only reads. It never changes anything in Quentn.
