Validate User Guide
The validate functionality checks your email message for common issues that could prevent your email from being sent. Run validate on your email and make corrections before starting any sending process.
Validate checks for the following required elements in an email message:
The presence of an unsubscribe link.
The presence of a physical mailing address.
Correct syntax for attributes.
Validate also checks each content area specified in any existing dynamic content rules.
If your email contains personalization strings, validate checks them against your subscriber attributes or data extension fields.
Use validate to improve your delivery rate and help ensure that the email message you send appears to the subscriber the way you intended it to.
