8BITMIME allows transmitting 8-bit data without Base64. Learn how it works and why it matters.
8BITMIME is an SMTP extension that allows sending message bodies containing 8-bit characters without requiring Base64 encoding. It can reduce overhead for certain content.
Support varies, and systems may still convert encoding depending on routing and gateways. For most senders, it’s handled automatically by modern MTAs.
