Cyber Monday email calendar.
Cyber Monday is the Monday after US Thanksgiving and works best as a distinct second act to Black Friday. Offer something different, such as bundles, tech or late arrivals, and use it to reach people who watched but did not buy over the weekend.
Key dates

Why it matters.
By Monday, subscribers have seen a stack of offers, so repeating the Friday email wastes an opportunity. The segment that matters most is the one that clicked, browsed or carted but has not purchased.
It is also the moment when list fatigue shows. Send less to people who ignored the weekend, and give your engaged subscribers a reason to open one more time.
Send plan.
1. The Sunday before
Send a short preview to clickers, saying what makes Monday different.
2. Monday morning
Send the main email to those who engaged over the weekend.
3. Monday midday
Send a reminder to carts and viewers with the items they looked at.
4. Monday evening
Send a last call to openers who did not click.
5. Tuesday
Suppress sale emails to everyone who bought and let post purchase flows take over.
Before you send.
- Build a segment of weekend clickers who have not bought.
- Exclude anyone who bought in the last 48 hours from sale reminders.
- Prepare a different offer or angle from Friday's email.
- Check that stock levels in the feed match your actual inventory.
- Schedule the evening last call with the end time in the subject line.
Segments to use.
- Weekend clickers who did not buy
- Cart abandoners from the last four days
- Customers who bought in the last week, who should be excluded from sale reminders
Subject line ideas.
- One more day, a different offer
- Still deciding? Here is what is left
- The items you looked at, still here
- Ends tonight, this is the last email

Common mistakes.
- Repeating Friday's email unchanged
- Emailing recent buyers a sale reminder for what they just bought
- Ignoring non openers and driving up complaints
This is a planning structure, not a promise of results. Your offer, stock, list and shipping options decide what is right, so test and adjust.
