Mail from INIS - can you easily spot it?

Hi All,

I've asked my neighbor to look after my mail, as I'm constantly travelling for work, sometimes for few weeks.
I'm worried that I won't be able to see the updates and act quickly, so I asked her to tell me if there is something for me from inis.

My question is - does the envelopes form inis are easy to spot? I get so much junk mail from the bank ect. so just want to make sure they are easy to spot

Thank you!
