I haven't received anything. Sometimes, emails are deleted directly by my provider, especially if they contain attachments, sorry for the inconvenience. Try to write again a short email, I'll send you another address where anti-spam is less aggressive.
I received your email, now!
It seems that the issue mainly comes from attached files. There is no option for this, unfortunately. On the other hand, it's an old email address I mainly use for my website, so it is quite exposed to spam nonetheless.
Thank you again for your review, I will put you on the hall of fame today.
