Tips for holiday subject lines
- Deadlines work. “Order by Dec 18” gives readers a real reason to act, without hype.
- Be inclusive when unsure. “Happy holidays” and “season’s greetings” work for mixed audiences. Use “Merry Christmas” if you know your readers celebrate it.
- Emojis: 🎄 🎁 ❄️ are well supported. Use one per subject line.
- Christmas Day: a short, warm greeting with no sales message builds goodwill.
Questions
When should I send Christmas marketing emails?
Gift guides do well from late November to mid-December. Shipping-deadline reminders work best in the week before your carriers’ cut-off dates.
Is Boxing Day a holiday in the US?
No. Boxing Day (December 26) is a public holiday in the UK, Ireland (St. Stephen’s Day), Canada, Australia and New Zealand, and it is a big sale day there.
What emojis work best in Christmas subject lines?
🎄 Christmas tree, 🎁 gift, ❄️ snowflake and 🎅 Santa are popular and display well. One is enough.
What day is Christmas 2026?
Christmas Day 2026 is on a Friday. Boxing Day is Saturday, December 26, so the public holiday moves to Monday, December 28 in the UK.
