The impact of mentioning COVID-19 in emails on deliverability is nuanced and has evolved. Early in the pandemic, some ISPs temporarily blocked emails containing COVID-19 related terms due to a surge in scams. While direct filtering based solely on these keywords is now less common, the topic can still indirectly influence deliverability due to heightened scrutiny and the potential for negative user engagement. Experts emphasize the importance of a good sending reputation, engaged subscriber lists, clear and vetted information, and adherence to email authentication protocols like DKIM, SPF, and DMARC. Maintaining consistent sending practices and avoiding sensationalized content are also crucial.
