Why did my Instantly campaign stop sending emails?
The Instantly help pages give 5 common reasons. The first to rule out: A campaign only sends during the hours and days you set. Outside that window, nothing goes out, so sends can look stopped.
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 Instantly help pages give, and how to check each one yourself.
What causes it?
A campaign only sends during the hours and days you set. Outside that window, nothing goes out, so sends can look stopped.
In the Instantly help:
Your campaign is configured to send emails only during specific hours or days, and it's currently outside that window.

In the Instantly help:
Each email account has its own daily limit on the total number of campaign emails it can send across all campaigns.

How would I know the day it starts?
- Feder reads your emails sent and your replies from Instantly each day and compares each day with your own history.
- It tells you when sending goes quiet or either number moves outside its usual range.
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 Instantly, which feeds Reach. Feder only reads. It never changes anything in Instantly.
