Dashes in email addresses can be a bit confusing, but don't worry, I've got the scoop. According to the rules set by the Internet Engineering Task Force (IETF), dashes are indeed allowed in email addresses, but they must be used in a specific way.
In fact, the IETF's specification for email addresses, RFC 5322, states that a hyphen (-) is a valid character in the local part of an email address. So, if you're thinking of using a dash in your email address, go for it.
However, it's worth noting that some email providers may have their own rules about dashes in email addresses. For example, some providers may not allow dashes in the username part of the address.

First Letter
Dashes in email addresses can be used, but there are some rules to follow when it comes to the first letter.

An email address is made up of two parts: the local part (before the @ symbol) and the domain part (the part after it). The local part can contain letters, numbers, and special characters like dashes or periods.
Email address format is pretty straightforward, but there are some rules to follow. The domain part, on the other hand, usually consists of letters and numbers, with periods separating the domain name levels.
You can use different characters in your email address, but make sure they don't harm it. For example, you need to pay attention to the hyphen placement. Dashes can be used in the middle of the username or domain part of the address.
Here are some specific rules to keep in mind:
- Dashes cannot appear at the beginning or end of the local part or the domain.
- Dashes can't be adjacent to each other in the local part.
