What is the maximum number of recipients for a test send?

The maximum number of recipients for a test send in Salesforce Marketing Cloud is typically set to five. This limitation is in place to help users efficiently preview and test their email content without sending it to a larger audience prior to the full campaign deployment. Test sends allow marketers to verify the appearance, formatting, and functionality of their emails in a controlled environment, ensuring that everything appears as intended before it reaches a broader audience.

While the other options present different numbers, choosing a number greater than five is not consistent with the platform's guidelines for test sends, as such larger numbers could complicate the testing process and lead to unintended engagement with more users than necessary at the testing stage. Choosing fewer than five recipients could restrict the diversity of testing scenarios needed to fully evaluate how the email renders across different devices and email clients.
