sent invoice Draft order not working

[knightyokohama]

Hi dears,

my clients do not get emails every times i create a draft order and i send invoice to them. I receive the notification but the client does not get any email. I added a couple of  hours ago also the TXT file to my domain. What else do i need to do?

Thank you so much

Just un update. If a client has a gmail, it goes to SPAM or to normal folder. In case a client email is @icloud, or　@Me, or i.softbank, he does not get any email.
