Hi Gert,

I have looked into this and found the bug. This particular email was not checking your preferences properly so it fell back to HTML email instead.

The fix is in the pipeline and will be deployed later this week, maybe even today already.

Apologies for the inconvenience,

Kind regards,
Johan ter Beest
RIPE Atlas team

Hi,
