I recently come acrossthis ribbon on StackOverflowthat dialogue about whetheremailsaddresses are case sore or not .
Say , you send an electronic mail to – contact@example.com , Contact@example.com , and CONTACT@EXAMPLE.COM . As you could see , all three of these emails have the same spelling but the first one is all low vitrine while the other two are a mix of both upper and lowly case . So , what happens when you station an email to all three of these ? Do they all go in the same mailbox or a different one ? Or in other Word of God – are e-mail addresses case sensitive ?
brusque answer , no . Inmostcases , Email address are not case sensitive . All three of them will arrive in the same mailbox i.e contact@example.com .
ProtonMail
Long answer , it bet . There are 2 parting to this question – the username before @ , and the domain name after it .
domain name ( i.e. @gmail.com or @techwiser.com ) arenot suit sensible , so example.com is same as EXAMPLE.COM .
Now , we are left with the username part ( the one that comes before @ ) . And technically , it ’s up to the server or the email providers to decided if they require to keep the username case sensitive or not .
Outlook
Most big electronic mail providers like Gmail , Outlook and even company email destination host on Google Suite are not eccentric sensitive . Just to avoid any unnecessary confusion . However , in extreme cases , some large companies , implement pillowcase sensitivity on their waiter as some people can often have the same first and last name . But in general , this produce more discombobulation , than the usability , which is why most standard email providers avoid case predisposition .
To test this theory , I did a quick experimentation .
Since we are already using contact@techwiser.com , I tried to create another email account with the first letter in upper case i.e. Contact@techwiser.com . And I instantly got an erroneousness on saying the username is not useable . I got the same error on Gmail , Apple ID , Outlook , ProtonMail – which allot to mostonline sourcesaccounts for more than 90 % of entire email by market place plowshare .
Apple ID
In unretentive , while it ’s technically possible to make the part before @ case sensitive , most pop electronic mail servers do not allow that .
It ’s safe to bear , your subject matter will be delivered to same email address , irrespective of upper or down pillowcase , as long as the username ’s spelling is right .
