Correct Answer: DSalesforce's mass e-mail functionality has a daily limit on the number of e-mails that can be sent, which cannot be sustainably increased for regular use. Developing custom Apex code and Visualforce pages would be complex and time-consuming, and downloading contacts to a CSV file bypasses the integrated functionalities of Salesforce, causing potential issues in tracking and personalization. Evaluating products on AppExchange is a pragmatic approach since it allows the use of specialized tools designed for mass e-mail communications, which can often handle larger volumes and offer features that align well with marketing needs.
