What are the best practices for sending a COVID-19 email to a large, unengaged list while preserving deliverability?

Summary

Sending a COVID-19 email to a large, unengaged list is strongly discouraged by experts and marketers due to potential harm to deliverability, IP reputation, and overall sender reputation.

Implement proper authentication protocols (SPF, DKIM, DMARC), maintain a clean email list by removing invalid addresses, gradually warm up IP addresses, set expectations with subscribers, and monitor email metrics closely. Documenting decisions and advice is also recommended. Adhering to email provider guidelines (Google, Microsoft) and building a positive sender reputation are essential for preserving deliverability.
