What is the maximum number of characters an email address can have?
The maximum number of characters for an email address is 320 characters. This includes both the local part (before the "@" symbol) and the domain part (after the "@" symbol). However, it's worth noting that many email providers have shorter limits for email addresses, so it's a good practice to keep email addresses reasonably short and within commonly accepted limits to ensure compatibility with most email systems.
The maximum number of characters for the local part (the part before the "@" symbol) of an email address is typically 64 characters. However, this limit can vary depending on the email provider or mail server configuration. It's important to note that while 64 characters is a common limit, not all email providers may support email addresses of this length, and shorter local parts are generally recommended for compatibility.
