Emails are electronic messages that you can send to prospects and customers to communicate with them and engage them with your marketing content. You can create and send emails using Marketing Cloud Account Engagement. However, some emails may get stuck in spam, which means that they are filtered out by the recipient's email provider or client and marked as unsolicited or unwanted messages. To avoid this, you can create a text version of the email, which is a plain text alternative to the HTML version of the email. A text version of the email helps with email deliverability and accessibility, as some email clients or devices may not support HTML or images. Creating clear calls-to-action, mobile-friendly versions, or domain keys and SPF may also help with email deliverability, but they are not as essential as creating a text version of the email. Removing the unsubscribe link from the email is not a good practice, as it may violate the email regulations and preferences of the recipients. Reference: Emails, [Create a Text Version of an Email]
