Final answer:
The solution for sending subscription renewal reminders should include using a Data Filter to identify expiring subscriptions, Template Based Emails for creating user-friendly email designs, and Automation Studio to automate the sending process without technical intervention.
Step-by-step explanation:
In order to send renewal reminders to customers whose subscriptions are about to expire, the customer's solution should include the following three components: Data Filter, Template Based Emails, and Automation Studio.
The Data Filter will be utilized to segment the subscribers based on the expiration data within the system, identifying customers whose subscriptions expire in 7 days and 15 days. Next, Template Based Emails will allow the marketing user to create professional emails without needing advanced technical skills. These templates can be reused for both sets of reminders.
Finally, Automation Studio will be used to automate the process of sending out the emails according to the segmented lists curated by the Data Filter. This ensures that the reminders are sent out on time, without manual intervention from a user who might not have technical expertise.
A Suppression List might be useful in other contexts to exclude certain subscribers from receiving communications, but it is not specified as necessary in the given scenario. Similarly, while a Triggered Send can send emails based on specific actions or events, it is not specifically required when the reminder dates are based on a set time frame in advance.
