Recovering deleted messages
If you've deleted a message permanently, by clicking Delete Forever in
your Spam or Trash, you won’t be able to recover the message using the
Gmail interface.
In the past, users have reported that they are missing all of their
messages as a result of unauthorized access. If your account was
compromised and you would like us to investigate whether recovery is
possible, please first complete this process to secure your account
and then file a report.
If you've moved a message to Trash, by clicking Delete, but it's been
fewer than 30 days and you haven't permanently deleted it, follow
these steps to put it back in your inbox:
- Sign in to Gmail.
- Click Trash along the left side of any Gmail page. (If you don't see Trash along the left side of your Gmail page, go to the Labels tab
in Settings, then click the show link next to the Trash label.)
- Locate the message you'd like to move to your inbox, and check the box next to the sender's name.
- Click Move to Inbox.
I'm guessing from the way you worded your question that you access your emails using the Gmail site (Ie, not using Outlook, Thunderbird etc)? If you do use one of these apps there may be ways, otherwise I think your out of luck pal.
