Final answer:
When "Send as Multipart MIME" is selected, it enables tracking of open and click activity in both HTML and text email versions, and automatically creates a text version to accompany the HTML email.
Step-by-step explanation:
When "Send as Multipart MIME" is selected during the email send process, there are several possible outcomes. However, two potential outcomes stand out:
- Open and click activity are tracked in either the HTML or the text version of the email, ensuring that interactions by recipients with either format are monitored for analytics purposes.
- An auto-generated text version will be sent with your HTML email. This ensures that if the recipient's email client cannot display HTML emails or they prefer text, they will still receive the message content in a readable format.
The options mentioned do not guarantee that the email will avoid detection by various SPAM filters, nor do they ensure that a custom text version will be sent with your HTML email, this would need to be set up separately.
