A designer can control the CSS styling for two assets in Marketing Cloud Account Engagement: landing pages and forms. Landing pages are web pages that capture visitor information and generate leads. Forms are web forms that collect visitor information and convert them to prospects. Both landing pages and forms can be customized with CSS to match the branding and design of LenoxSoft. Form handlers and social posts are not assets that can be controlled by CSS in Marketing Cloud Account Engagement. Form handlers are connectors that allow Marketing Cloud Account Engagement to use external forms on your website. Social posts are messages that can be sent to your social media accounts from Marketing Cloud Account Engagement.ReferenceCustomize Landing Pages with CSSCustomize Forms with CSS

Marketing Cloud Account Engagement uses a tracking pixel to track HTML email opens. A tracking pixel is a small image that is embedded in an HTML email, and it loads when the recipient opens the email and downloads the images. Marketing Cloud Account Engagement uses the tracking pixel to record the email open activity and associate it with the prospect record. Marketing Cloud Account Engagement does not use a tracking link to track HTML email opens, because a tracking link is a link that is modified by Marketing Cloud Account Engagement to track the click activity and redirect the recipient to the original URL. Marketing Cloud Account Engagement does not track email opens only if a link is clicked, because email opens and link clicks are different activities that are tracked separately. Marketing Cloud Account Engagement does not use a tracking pixel to track text email opens, because text emails do not support images or HTML.

According to theSalesforce documentation, an automation rule is an automation tool that can be used to send an email to a prospect when a form is submitted and a specific field value is selected on that form. An automation rule can be configured to trigger an action (such as sending an email) when a prospect meets certain criteria (such as submitting a form and having a specific field value). The criteria can be set to Match All or Match Any, depending on the logic required. In this case, the Match All option should be used, as the prospect needs to meet both conditions (form submission and field value) to receive the email. A completion action is another automation tool that can be used to perform an action after a prospect successfully completes a form, but it cannot be used to check for a specific field value. A dynamic list is a list of prospects that is updated automatically based on certain criteria, but it cannot be used to send an email directly. A list email is an email that is sent to a specific list of prospects, but it cannot be triggered by a form submission or a field value. Reference:Salesforce documentation
