Why isn't my MailerLite subscriber count going up?
The MailerLite help pages give 4 common reasons. The first to rule out: With double opt-in, new sign-ups are unconfirmed until they confirm, so they do not add to your active count until then.
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?
With double opt-in, new sign-ups are unconfirmed until they confirm, so they do not add to your active count until then.
In the MailerLite help:
Until the subscription is confirmed, these emails are considered unconfirmed subscribers.
What are unconfirmed subscribers?, read 2026-11-12.MailerLite gives an address that already unsubscribed as a reason an import row was not added, so re-importing past subscribers does not grow the active count.
In the MailerLite help:
The email address is already unsubscribed from your list.

In the MailerLite help:
The email address is already labeled as Bounced, Unconfirmed, or Spam complaint in your account.

In the MailerLite help:
We'll automatically clean duplicate instances of email addresses from your list.

How do I check it myself?
After an import, compare how many subscribers MailerLite says it added with how many failed.
In the MailerLite help:
you’ll be notified how many subscribers were added successfully and how many failed (if any).
How to import subscribers, read 2026-11-12.If many sign-ups are stuck as unconfirmed, the fix is getting them to confirm, since MailerLite allows setting them active only with their permission.
In the MailerLite help:
It is possible to set unconfirmed subscribers as active only if you have their permission to do so.

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.
