Content blocker issue when opening "mandrill app" link

Trebso

Whenever I open a link in a newsletter from espc.com, eg:
https://mandrillapp.com/track/click/30476605/espc.com?p=eyJzIjoib1NWTDY0Y0lmNHMyd1dNZk5mQmFTRlhhM2tnIiwidiI6MiwicCI6IntcInVcIjozMDQ3NjYwNSxcInZcIjoyLFwidXJsXCI6XCJodHRwczpcXFwvXFxcL2VzcGMuY29tXFxcL3Byb3BlcnR5XFxcLzM2MzE0MDExP2NlPTEmdXRtX3NvdXJjZT1wcm9wZXJ0eS1hbGVydC1zZWFyY2gmdXRtX21lZGl1bT1lbWFpbFwiLFwiaWRcIjpcImI1ZGZkNGM0Y2RhNzQyODM5MTkwOTk2YzdlMTcxMmY3XCIsXCJ1cmxfaWRzXCI6W1wiZGEzMmFhNjZjZWE4OTQ2ODBhMjY1YWY2YTBlOTEzMGE5M2NiODcwN1wiXSxcIm1zZ190c1wiOjE3NDczMTAwOTF9In0

I get this error:

It only happens on iOS and iPadOS, not Mac.

If I go direct to espc.com I can open links without problem.

Links to open normally.

Yes, you are trying to open a commercial link, so the tracking blockers come into action.
You need to deactivate them.

A couple of questions:

Why is it happening on iOS and iPad but not Mac?
can I disable content blocker for specific domains? Ie just mandrillapp or does it apply to all sites?
