What is one outcome when "Multipart MIME" is selected during an email send?

When "Multipart MIME" is selected during an email send, one key outcome is that an auto-generated text version will be sent along with the HTML email.

Multipart MIME is a standard that allows emails to be sent in multiple formats. By creating both an HTML version and a plain text version of the email, it ensures compatibility with different email clients and user preferences. Some recipients may prefer to view emails in plain text due to accessibility reasons or personal settings, while others may enjoy the formatted style of HTML emails. By providing both formats, the sender enhances the likelihood that the message will be correctly displayed and engaged with, regardless of the recipient's email client capabilities.

This approach not only improves the recipient's experience but also increases the chances of the email being read and acted upon. The other options relate to different aspects of email sending or tracking but do not represent the specific outcome linked to the selection of Multipart MIME.
