Why did my MailerLite subscriber count suddenly jump?
The MailerLite help pages give 3 common reasons. The first to rule out: Every form or landing page adds the people who sign up through it, so a busy form or a new landing page can lift the count quickly.
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 MailerLite help pages give, and how to check each one yourself.
What causes it?

How do I check it myself?

In the MailerLite help:
you can identify subscribers who signed up via each form by checking its analytics.

How would I know the day it starts?
- Feder reads your active MailerLite subscriber count each day and compares each day with your own history.
- If the count moves outside its 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 MailerLite, which feeds Reach. Feder only reads. It never changes anything in MailerLite.
