I travel a lot and always had problems following up on the postal arriving home. As a result I missed a few payments or notices and it took me much more effort to get these things right afterwards.
With the Internet being everywhere I now found companies (e.g. private box) that provide a PO box as a service. For any incoming letter you will receive a notification by email. When you follow their link and log into their website you will be able to get more details such as the sender and size of the letter. At this stage the letter has not been opened so that you don’t receive information on its content.
You can then chose if you want them to open and scan the letter for you, forward it or throw it away.
Since I am using this service I never missed any mail again and I significantly improved my scanned document filing on my Internet server. This is the right thing for everyone who travels a lot.
