Automatic emails not received from @kraken.com and @teamviewer.com

Simple !

for Kraken
when i log on their website, they send email with an authentification code inside.

for Teamviewer
when i log on their website, they send an email with an URL to confirm Browser/device is trusted

as i’m not able to see their email neither in mailbox neither spam folder, for both of them i cannot use those platforms with my mailbox managed on MIAB.
