Your first step will be to pick a plan. You can pick between personal and business plans, as well as terms (month to month and annual terms.) From there, you will need to complete a change of address with the USPS, so that they can forward all your mail to the virtual address you will be given, when signing up with US Global Mail.
From there, all mail that you receive will generate an e-mail notification with a scanned image of your envelope or package. If you need to have the interior documents of your envelope scanned, you can request that from within your virtual mailbox account as well. For packages, you can have them shipped to your location, and if you are overseas, get them with up to 80% off retail shipping rates.
Finally, you can have mail items that you do not want, shredded and all junk mail gets shredded before it even enters your account.
