For what is a private 'Homepage-Mail-Account' useful?

Imagine you are somewhere far away from home. Your smart-phone has no reception, the battery is squeezed down and at the airport or at your hotel there is a computer with an internet connection but to all annoyance you have forgotten the access data to your e-mail portal. This page might help you. For sending an e-mail to any address, you need only the 'unlock code' of this page. Certainly, you also need the correct e-mail address of the recipient and of course the first name or surname of the person you are going to write. The message can have a length of a fully written page of a business letter. Exactly speaking, you can type 3800 characters and space marks. Down at the left side of the e-mail-form, a counter will inform you about the number of characters which still can be placed. This mail account should not be used for messages which infringe law. Please confirm your legal use of this account and mark the corresponding checkbox otherwise no mail can be sent. Be aware that the recipient can't answer your e-mail over this account directly! If this note sounds reasonable for you, please send me your full address and your telephone number via the form of registration, I will send you the 'unlock code'.
