clerk.io is the link/tracker domain of Clerk.io, a Copenhagen-based e-commerce personalization and email-recommendation platform used widely by Scandinavian webshops. Its URLs appear in legitimate transactional and newsletter mail from thousands of stores.

It is currently listed on uribl.rspamd.com (plaintext query returns 127.0.0.2), which makes RSPAMD_URIBL (+4.5 default) fire on legitimate retail newsletters. Observed at a Danish mail hosting provider: an entire campaign of legitimate pharmacy newsletters crossed the spam threshold primarily due to this listing.

If you consider tracker domains greylist material rather than whitelist (as with list-manage.com), a '# grey' entry would also resolve the FP pressure via delisting instead.
