Is there a way to check if a mail is received bij zoho?

I've been using zoho for a long time and very pleased. But I have the following issue:

we use a group because we have a group of editors who need to receive press releases sent to one mailadres. This works.
But on occasion we miss e-mails sent to us. Is there a way to check if these mails even reach the zoho servers and get marked as spam, I can't seem to find a 'spam folder' for a group.

Please help me out!
