BFCM stands for Black Friday Cyber Monday, the four-day stretch from the Friday after Thanksgiving through the following Monday that represents the highest-volume sales period of the year for most ecommerce stores.
The Problem That Defines the Weekend
What is BFCM, from an inbox’s perspective, is the one weekend a year when every competing store sends email at the same time, to the same shoppers, chasing the same limited attention. The challenge isn’t really getting a sale ready, most stores manage that. It’s standing out inside an inbox that’s receiving a dozen other nearly identical “biggest sale of the year” emails within the same 48 hours. A Black Friday Cyber Monday email calendar that looks like everyone else’s is competing on discount depth alone, which is rarely a winning position.
Why the Real Work Happens Weeks Earlier
A well-planned BFCM campaign is decided long before the actual weekend, not during it. List growth, segmentation, and abandoned cart automation all need to already be in place, since there’s no time to build any of that once the weekend starts and volume spikes. Stores that try to improve their setup mid-weekend are usually reacting to a problem, a low open rate, a broken automation, rather than executing a plan, which tends to show in the results.
What Changes About Send Strategy This One Weekend
BFCM email marketing departs from a normal calendar in a few specific ways. Send frequency goes up, since a single teaser-and-launch pair isn’t enough coverage across four days of shifting urgency. Abandoned cart recovery delays typically get shortened, since inventory can genuinely sell out mid-weekend in a way it rarely does the rest of the year, and a standard hour-long delay before the first reminder can cost a sale that would have converted with a faster follow-up. A BFCM campaign that treats this weekend like any other send cadence is usually leaving revenue on the table.
The upside of getting the BFCM email strategy right is disproportionate to the effort. For most ecommerce stores, this single weekend has more influence on quarterly revenue than any other individual campaign runs the rest of the year, which is exactly why serious BFCM email marketing planning starts well before November.
A Counterintuitive Number Worth Knowing in Advance
Klaviyo’s 2025 BFCM data revealed something that surprises a lot of marketers:
- Open rate: around 18 percent during BFCM, compared to a roughly 21.5 percent annual baseline, purely because inbox competition is so much fiercer than any other time of year.
- Conversion rate: roughly doubled the annual average, reaching 6.4 percent versus 3.2 percent, despite the dip in opens.
- Revenue per email: climbed to about 0.38 dollars, compared to 0.12 dollars on a normal send.
The lesson in that gap: a lower open rate during BFCM doesn’t signal a weaker campaign, it reflects a genuinely more competitive inbox, and the real performance story shows up further down the funnel in conversion and revenue, not in the open rate alone.
