To secure a CloudPage and its elements (such as images) using SSL, a single SSL certificate can be used if both the CloudPage and the images are hosted under the same domain. This SSL certificate ensures that all content served from that domain is encrypted and secure.

TheFormatCurrencyAMPscript function is used to format a numeric value as a currency. To return a value of
$6.96, the function would correctly format inputs like:
* 6.96 (B)- This is a direct numeric value that will be formatted to $6.96.
* 6.96 (D)- Same as above, the numeric value is directly formatted to $6.96.
UsingFormatCurrency(6.96)in AMPscript will result in$6.96.

To create a Call-To-Action (CTA) link in an email that will display personal information about the subscriber on a landing page, the developer should use theAMPscript CloudPagesURL function (A). This function generates a URL for a CloudPage and can include parameters such as SubscriberKey or EmailAddress, which will be passed to the landing page securely.
Example usage:
rectTo(@url)=%%">View Your Information</a>
This ensures that the SubscriberKey is securely passed to the CloudPage without exposing it directly in the URL.
