Implementing set expiry dates can be done in various ways:
Dynamic Content: Use dynamic content blocks that change based on the date. For instance, a promotional banner can automatically update to a default image once the offer expires. Expiration Scripts: Employ JavaScript or other scripting languages to hide or change content after a specific date. Automated Campaigns: Utilize automation tools to send follow-up emails that either remind subscribers of the expiring offer or notify them that the offer has ended.
