How would I know the day it starts?
- Feder reads your email clicks and your emails delivered from Mailgun each day and compares each day with your own history.
- It tells you when clicks go quiet or move outside their 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 Mailgun, which feeds Interest. Feder only reads. It never changes anything in Mailgun.
