Do Capitals Matter in Email Addresses and What You Need to Know

Capitals can make a big difference in email addresses, but it's not as simple as just using them or not using them. In fact, the rules around capitalization in email addresses are quite specific.

In most cases, the email address is case-insensitive, which means that it doesn't matter whether you use uppercase or lowercase letters. For example, "[email protected]" and "[email protected]" are treated the same.

However, there are some exceptions to this rule. Some email providers, like Gmail, are more strict about capitalization and may not recognize email addresses with mixed case. This means that if you're using a Gmail account, it's best to stick with all lowercase letters.

While capitalization doesn't affect email delivery, maintaining consistency in letter case can make email addresses easier to read for both humans and email servers.

An email address is composed of two main components: the local part and the domain part, which are separated by the “@” symbol.

The local part, or username, can contain up to 64 Latin characters and numbers, and periods are also allowed within it.
