What Cyber Monday email frequency is too much?

Question

As an e-commerce marketer preparing for Cyber Monday, I'm struggling to determine the right number of promotional emails to send without annoying my subscribers or causing email fatigue. I want to maximize sales and engagement, but I'm worried about potential unsubscribes or decreased open rates if I send too many messages. How can I strike the perfect balance between being informative and not overwhelming my audience during this critical shopping period?

Cyber Monday Email Frequency: How Much Is Too Much?
Email fatigue is a real risk during BF-CM week. By Cyber Monday, your list has already received multiple Black Friday emails. The threshold for unsubscribes is lower than usual, so frequency decisions matter more than any other week of the year.

Smarter than Frequency: Segmentation
Instead of sending 3 emails to everyone, send targeted emails to smaller segments:

8 AM - Everyone: Cyber Monday launch email, full sale announcement
12 PM - Non-openers only: Resend with different subject line to those who didn't open the 8 AM email
9 PM - Cart abandoners only: Final urgent reminder to people who clicked but didn't buy

Signs You're Sending Too Many

- Unsubscribe rate above 0.3% on any single send
- Open rates below 15% on your second email of the day
- Spam complaint rate above 0.1%
- Replies with "please stop emailing me"

Let Growth Suite Handle the On-Site Follow-Up
Instead of a third Cyber Monday email, use Growth Suite Trigger Campaigns to catch visitors when they land on your store. You send fewer emails, reduce list fatigue, and still capture the conversion - just at the right moment on-site rather than in their already-crowded inbox.
