Where did Mail.app just put my email?

Solution 1:

Create a Smart Mailbox with "Message is Unread" and sort it by Date Received. I have this setup as my default mailbox for processing my email. I also have the Mail.app dock icon badge set to point to this Mailbox so I can see how much unread mail I have, though in your case this won't be an advantage.

Pro Tip. Just mark all those messages as unread read. You're never going to read them.

Solution 2:

When I used Mail, I had a lot of smart mailboxes, but one of the most used ones (and their main conditions) where:

UNREAD (message is unread)

TODAY (date received is TODAY)

YESTERDAY (date received is YESTERDAY)

WEEK (date received is within 7 days from now)

MONTH (date received is within 30 days from now).

FLAGGED (message is flagged)

And every year, I’d create a (new) one like this:

2010 (message is received between 1/1/2010 and 31 dec 2010).

2009 (like 2010, but with the correct dates)

etc.

Those ones were inside a folder. It allowed me to group messages by year, because sometimes I needed a message that I got in 2008…

Of course I’d add other conditions like not in spam/trash, etc. Sometimes you have to “nest” smartmailboxes. Like have one that is message is not in spam or thrash. And then a new smart mailbox that says: Message is not in + other conditions.

The reasoning behind all this smartmailboxing is that once you start getting thousands of emails, searching in mail is not fast. For that reason I switched to Gmail, but that’s just my personal preference.
