What is a critical step after constructing dynamic content in email but before sending it?

Previewing the email using samples is an essential step after constructing dynamic content. This allows you to see how the email will render for different segments of your audience, ensuring that the dynamic content appears correctly based on the recipient's profile. By using samples, you can test various scenarios to identify how each segment will experience the email, checking that personalized elements are functioning as intended.

This step helps mitigate risks of miscommunication or formatting issues, which can occur if the dynamic content does not display properly. By previewing, you can also assess the overall visual design and ensure that it aligns with your brand guidelines, ultimately contributing to a more effective email campaign.

The other choices, while important for different aspects of campaign management, do not specifically ensure that the dynamic content is appropriately configured before sending. Assigning unique identifiers is vital for tracking, verifying lead scoring parameters is crucial for managing leads, and obtaining approval ensures compliance with policies, but none of these steps directly address the need to ensure that dynamic content is displayed correctly for the intended recipients.
