An Email Address is the address of the account that you use to send and receive emails. It is displayed to the recipients of your emails so that they know who sent the email.
Each email address can only be assigned once worldwide and is therefore exclusively available to you. You cannot change email addresses, but you can delete them at any time.
There are certain requirements for spellings with special characters as these are not always used internationally in every country.
An email address consists of an @ sign, a local part in front of it and a domain part behind it, as in our example firstname.lastname@example.org:
The domain part depends on the domain under which the email address is created - in our example this is example.com. This varies from provider to provider, so a domain part can also be gmail.com or outlook.com if you use an email address of these providers.
If you have registered your own domain, such as www.yourbusinessname.com, your email addresses that you set up for the domain have it as a domain part.
The local part - which is account in our example email@example.com - the part of an email address before the @ symbol and can be nearly anything you want with exception to the use of certain special characters. Here you can, for example, use your own name or the name or department of a company.
If you use an email address with a mail provider such as gmail.com or outlook.com, it is possible that the combination with the desired domain part is already registered. In this case, you will need to consider alternatives for the local part of your email address.
If you use your own domain instead, these restrictions do not apply because it is only you who can create email addresses that match your own domain.
