Email Marketing Best Practices for Seasonal Campaigns
Plan 4-6 Weeks Ahead
Major holidays require early planning. Start campaigns 4-6 weeks before for optimal results.
Segment Your Audience
Not every holiday resonates with everyone. Segment by geography, interests, and past behavior.
Be Authentic
Only engage with holidays that align with your brand. Forced participation feels inauthentic.
Test and Iterate
A/B test subject lines and send times. What worked last year might not work this year.
