Why does an email address have small letters only?
Suppose my mail ID is ashwani@google.com (it's not mine by the way) Now there are two parts domain name 'google.com' and your user name 'ashwani' Domain name is case insensitive, while your user name is case sensitive. When you send an email, firstly it is delivered to domain address. From there is is delivered to your username. This case sensitivity may create confusion (it means ashwani@google.com and Ashwani@google.com are two different mail addresses) To avoid this confusion mail IDs are generally in small case. But in case of providers like Gmail, yahoo, hotmail; they consider everything in small case. For them Ashwani@gmail.com is equivalent of ashwani@gmail.com
Can an email address have capital letters?
An email address is made of very two different parts. Basically, the part after the AT sign tells the Internet which email server contains your mailbox and thus should receive the email. The part before tells that server whose mailbox is addressed — which user is supposed to get the message.The the part after the AT sign, called the domain name, is case insensitive everywhere on the Internet. That is, on the web there can be no difference between http://www.google.com/whatever and http://WWW.GOOGLE.COM/whatever; in FTP, there can be no difference between ftp://ftp.somerepository.com and ftp://FTP.SOMEREPOSITORY.COM; and thus with emails there can be no difference whatsoever between myaddress@mydomain.com and myaddress@MYDOMAIN.COM.For this reason, the first part of the answer is straightforward: an email address can have uppercase letters in its domain part and they do not count.For the first part of the address the questions is slightly more complicated. There have been many revisions over the decades to the specific protocol (called an RFC in Internet-speak; basically, a set of rules which everybody must respect for interoperability). The latest core version is RFC 5322 but that is supplemented by many other protocols such as RFC 6854. There is a protocol which explains how email is forwarded (thats the SMTP pane in the preferences of your email software). The latest version, RFC 5336, says that the first part of the address may be case sensitive, but the previous version of the same, Simple Mail Transfer Protocol, said that it better not.exploiting the case sensitivity of mailbox local-parts impedes interoperability and is discouragedSo, there might exist on the Internet some mail server which contains two different mailboxes, one called myaddress@mydomain.com and the other called MyAddress@mydomain.com. Such cases, if they exist, are rare. I checked, and Google’s Gmail is case insensitive in addresses. Postfix, which is the most used such software under Linux, is case insensitive. Et cetera. As others have said, thus, email addresses are best considered case insensitive.So, the fast and easy answer to your question is: you can use uppercase letters but there’s a 99.99% chance that they make no difference whatsoever.[Edited Jan 10th 2018; thanks to Philip Newton for pointing out that my first answer was way too simplified].

When mailing a parcel, what happens if I use a return address different from the one I'm mailing from?
Nothing happens.The Postal Service is only concerned with the fact that correct postage has been paid, that the package doesn’t contain flammable or explosive items and that there is no intent on the sender’s part to defraud or extort any possible recipient. They don’t care if the sender’s current address is the return as the sender will have to explain if the package itself is lost why they chose to use a different return address.I have personally sent many packages using my home as a return address even when I wasn’t at home. This was to ensure that if the package couldn’t be delivered, it would be returned to my home and then I could ship it again.
Can an email address include Arabic letters, i.e., وحيد@hotmail.com?
The format of Internet e-mail addresses is defined in RFC 2822, which permits them to consist of only a subset of ASCII characters. As defined in RFC 2821, the local-part of an e-mail address has a maximum of 64 characters (although servers are encouraged to not limit themselves to accepting only 64 characters) and the domain name a maximum of 255 characters. Unlike everything else in the header, the local-part "MUST BE treated as case sensitive. [...] However, exploiting the case sensitivity of mailbox local-parts impedes interoperability and is discouraged." Local part is the portion of a mail address before the @ character. This normally identifies a particular mailbox within a site mail system so is not usually of interest to other mail systems. According to RFC 2822, the local-part of the address may use any of these ASCII characters: * Uppercase and lowercase letters (case sensitive) * The digits 0 through 9 * The characters ! # $ % & ' * + - / = ? ^ _ ` { | } ~ * The character . provided that it is not the first or last character in the local-part. Additionally, RFC 2821 and RFC 2822 allow the local-part to be a quoted-string, as in "John Doe"@example.com, thus allowing characters in the local-part that would otherwise be prohibited. However, RFC 2821 warns: "a host that expects to receive mail SHOULD avoid defining mailboxes where the Local-part requires (or uses) the Quoted-string form". Notwithstanding the addresses permitted by these standards, some systems impose more restrictions on email addresses, both in email addresses created on the system and in email addresses to which messages can be sent. Hotmail, for example, only allows creation of email addresses using alphanumerics and . _ - and will not allow sending mail to any email address containing ! # $ % * + / ? | ^ { } ` ~.

What happens if I made a mistake when writing the address on an envelope, and crossed it out?
I was writing the address on an envelope for a letter I'm mailing, and I made a mistake . I don't have white out, so I crossed it out and wrote the correction under it . It's only a small mistake, just 4 letters. Will the letter still send??
Does it matter if I used a different name then on my Credit Card?
Yes is will probably be rejected. But maybe not. I assume your brother has the same last name... and all the other info, including the card security code is correct... I have left out my middle initial and not had the transaction rejected... first name? Anyway, you can go back into Amazon and edit the order. Or wait until they send you the rejection and than edit it.
