Unable to receive emails from Instagram

Good morning

I am not receiving emails from Instagram to confirm the security of my account or to recover my account. I tried several “bluewin.ch” email addresses and it’s always the same. Is the domain “instagram.com” blocked by Swisscom because I don’t see any other explanation

Who has already encountered this problem and has a solution?

Thanks in advance

That’s the first thing I did… there’s nothing in spam.

If the messages do not arrive in my inbox even though they were sent to the correct address by Instagram, it is because the problem is between departure and arrival… but where???
