Universal Containers (UC) is using Sales Cloud and Service Cloud. UC wants a solution that can tend scheduled emails on a dairy, weekly, or monthly basis to existing customers and prospects. UC also wants to track if customers have opened the emails. There can be as little as 1,000 emails in a week or as many as 100,000 emails in a month, depending on the season.
Based on that criteria, which solution should the Solution Architect recommend to UC?
