What is the maximum number of recipients that can be specified in a single workflow email alert?

Correct answer: 25

Option D, 25, is correct because Salesforce enforces a hard limit of 25 recipients per single workflow email alert; this includes any combination of users, roles, public groups, and email addresses specified on the alert. Option A stating unlimited recipients is incorrect, as Salesforce imposes this cap to prevent mass-mailing misuse through workflow automation. Option B, 5000, refers to daily email limits that apply to an entire org, not to the recipient count on a single alert definition. Option C, 5, significantly understates the actual limit and would be too restrictive for most common notification workflows involving teams.
