Are email addresses case sensitive?
  • No. Case does not matter in email addresses. Although having all lowercase letters makes the email address simpler to read, the error will not prevent your messages from being delivered.
  • An old server or application may not read capitalization appropriately on rare circumstances. Even yet, the vast majority of today's email servers are capable of handling uppercase letters in an email address.
  • Combining caps and lowercase letters in your email address can make it tough to understand.
