Why do my Mailchimp Transactional (Mandrill) unique clicks look wrong?
The Mailchimp Transactional (Mandrill) help pages give 4 common reasons. The first to rule out: Clicks are only recorded when click tracking is on. If it was turned off, clicks stop being counted.

How do I check it myself?
Compare unique clicks with total clicks. Total clicks counts every tracked click, so it is usually higher than unique clicks.
In the Mailchimp Transactional (Mandrill) help:

Activity and Reports, read 2026-11-12.If you set up your own tracking domain, it changes the link address people see, not whether clicks are counted.

How would I know the day it starts?
- Feder reads your unique clicks and your emails sent from Mailchimp Transactional (Mandrill) each day and compares each day with your own history.
- It does not sort real clicks from link scanners. 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 Mandrill, which feeds Interest. Feder only reads. It never changes anything in Mandrill.
