HTML Comment Removal Use Case
An email marketer wants to send a promotional email campaign to his subscribers. He create an HTML email template with some comments in the code to remind yourself of certain elements or to leave notes for other developers.
When he send the email campaign, some subscribers report that they are not receiving your emails, while others report that the emails are taking a long time to load or appearing broken in their email clients.
Upon investigating the issue, he realize that the excessive HTML comments in the email’s code are causing the email file size to be much larger than necessary, which is causing the email to load slowly and inconsistently across different email clients. Additionally, some email spam filters may be flagging the emails as spammy due to some of the wording in the HTML comments.
