How to avoid base64 in smtp email?

There is no way to completely avoid using base64 encoding in SMTP emails, as it is a standard method for encoding binary data into a plain text format that can be transmitted over email systems. However, there are some tips to minimize the use of base64 encoding in SMTP emails:

1. Minimize the size of attachments: Try to keep the size of attachments as small as possible to reduce the need for base64 encoding. Consider compressing files before attaching them to emails.
2. Use plaintext instead of HTML: Plain text emails are usually smaller in size compared to HTML emails, which can help reduce the amount of base64 encoding required.
3. Avoid embedding images: Instead of embedding images directly into the email body, consider including a link to the image hosted on a website. This will reduce the size of the email and minimize the need for base64 encoding.
4. Use a more efficient encoding method: Some email clients and servers support other encoding methods, such as quoted-printable, which may be more efficient than base64 encoding for certain types of data.

Overall, while it may not be possible to completely avoid base64 encoding in SMTP emails, following these tips can help minimize its use and improve the efficiency of email communication.
