Holiday email marketing best practices for 2026 (and beyond)

Summary

Holiday email marketing carries higher volume and stakes during the seasonal shopping period, making planning, deliverability, personalization, and post-holiday retention central concerns. The guide recommends warming sending volume before Black Friday and Cyber Monday, increasing it by only 25–40% at a time to avoid sudden mailbox-provider signals. It also calls for a calendar with one or two lower-volume days each week, list hygiene, segmentation, testing, and journey-driven campaigns that account for shipping and fulfillment constraints. For holiday-season signups, the post-holiday process uses sign-up date or source cohorts, monitors open and click rates, and can reduce frequency, run re-engagement campaigns, or suppress addresses after 30–60 days without engagement. Examples and templates emphasize concise, value-driven content, specific offers, and personalization such as location or past purchases.

Takeaways

1. 1

   The guide suggests sending only to addresses that opened or clicked within the past six months, and preferably prioritizing recipients with positive engagement in the past three months.

2. 2

   Less-engaged recipients can be mailed at reduced frequency and segmented to a different IP group and subdomain or domain combination.

3. 3

   Holiday subject lines should lead with a specific offer, such as “Boots up to 60% off,” rather than relying on a generic Black Friday announcement.
