Why are fewer of my contacts getting my Brevo campaigns?
The Brevo help pages give 5 common reasons. The first to rule out: Contacts on the email blocklist no longer get any of your campaigns, so a growing blocklist means fewer campaign emails sent.
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 Brevo help pages give, and how to check each one yourself.

How would I know the day it starts?
- Feder reads the campaign emails Brevo sent each day and compares each day with your own history.
- If sends go quiet or move outside your usual range, Feder tells you.
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 what Feder reads from Brevo, which feeds Reach. Feder only reads. It never changes anything in Brevo.
