But wouldnt the user face this issue all the time if they have a case sensitive mailbox but type their own address in the wrong case? So the assumption may be that a user with a case sensitive mail box is used to typing in the correct address?

No — many accounts aren’t created by the people that use them, and in any case we shouldn’t be relying on correct repeated string input and then blaming the user for a fulfilment process failure due to a typo from hours ago that we silently accepted at the time, and (worse) we can’t even distinguish between a capitalisation error and a discontinued recipient, even if it was previously verified. As designers/developers, it’s our problem to solve.

  > No — many accounts aren’t created by the people that use them Can you elaborate on this? I can only think of 2 examples, but neither seem like good ones: 1- someone holds power of attorney over someone else, and register an account (email account?) in their name. But if there's PoA involved, the 2nd person isn't (probably ?) able to manage an email account on their own, so this doesn't seem a meaningful distinction to worry about. (though if it's not an untreatable condition, it's possible that they might resume using their email account themselves, I guess) 2- the account is created by your ISP when you register, and they "helpfully" choose a username for you. So from this point of view, you didn't truly "create the account"

    3- Work e-mail is usually created by IT and users have no influence over it.

      4 - school and academic emails are also often created the same for as work emails; following a Policy without any user involvement.

        5- parental/grandparental accounts. What’s more, speaking from our own support mailbox, these are the folks most likely to miscapitalize their email address.

  Wait a second. Back up. Let's be clear here: the case you are talking about is the user entering their own email address incorrectly, and you're saying we as designers/developers should make a system that knows this and sends it to the correct email? What? Huh? If Person@place.com and person@place.com are two different recipients, how the hell is my application supposed to know which one you actually mean!?

    The same way we deal with all email validation. Verify it once at application signup, then rely on the precise verified form. It is unrealistic to expect end users to get the capitalisation of their email address consistently right. It is realistic to expect it to be done right at signup, since in the best practice case this’ll include a verification loop.

  Okay... so how is this issue currently handled? Say I create a new email account: lAsZlO@inopinatus.com and the mailbox is case sensitive. Next I create a youtube account but as E-Mail address I enter laszlo@inopinatus.com and I am told to click the link in the confirmation E-Mail... that I never receive. Well I do not like youtube anyway so I head over to hackernews and create an account to write this comment. Oh no I can not because I typed my E-Mail address in lowercase again. So now I am wondering if there is some error so I open your homepage, search for the support page and file a bug report, typing my E-Mail address in lowercase into the E-Mail field. I never receive your response telling me to write my E-Mail address in the correct casing. I come to the conclusion that my E-Mail account just does not work and create another one at a provider that is case insensitive. OR I figure out/am told that the case is important and will never forget it again. So where exactly are services like youtube or hn that ask me for my E-Mail responsible for handling upper/lower case correctly? The solution could still be: store both the hash for the canonicalized address and the hash of the exact address of which you know that it worked at some point in time. If the user enters the address later the matches the one but not the other issue a warning that should they not receive the E-Mail to double check their spelling.

    I suspect you'll have difficulty creating a case sensitive email address on any public email service.

      Actually I do perform case routing & delivery in one of my Fastmail accounts. It’s not the default, but it is possible, if you’re willing to write or generate Sieve, which I am.

        What is your use case for case sensitivity? Just curious.

  If the email provider says that email addresses are case sensitive, then that's the truth you live with, it's not your system, not your design and you can't dictate other systems how they should work.
