Best period to dispatch Black Friday emails in 2026

With 78% of marketers using email as part of their multichannel strategy, it’s no astonishment that inboxes are crowded alongside competing promotions during Cyber Week. Getting your dispatch timing correct can assistance your communication get seen and acted on.

That’s why there’s no deficit of direction on whenever to send.

Send at 6 a.m. Send at 9 a.m. Send on Tuesday. Send before everyone alternatively does.

But much of that direction is according to person else’s data, and sometimes, it contradicts itself.

So we looked into our own data – Hostinger Reach’s sender basis during Black Friday 2025 – to detect the dispatch and involvement patterns throughout the BFCM (Black Friday and Cyber Monday) week.

One of the most striking findings is additionally the most counterintuitive: the busiest sending hours were never the best-performing ones, during moderate-traffic windows consistently performed better.

Here’s a nearer appearance at what the data showed and how you can use it to decide whenever to dispatch your own Black Friday emails.

How we measured the Hostinger Reach data

We analyzed email quantity and involvement data from Hostinger Reach during the BFCM week in 2025, examining whenever emails were delivered and whenever recipients opened or clicked them. 

This let us nexus all involvement event to the hr the email was initially delivered, fairly than the hr whenever the open or click happened.

To see how patterns shifted as Cyber Week approached, we compared three periods: a baseline week (November 3–9), a ramp-up period (November 17–23), and Cyber Week itself (November 27–December 1). 

All times are recorded in UTC.

Best day to send: Black Friday wasn’t the busiest day

Despite being the day the entire week is named after, Black Friday classified fourth by dispatch quantity in Reach’s data. 

Cyber Monday accounted for the largest portion of the week’s email quantity at 26.6%, followed by Thanksgiving at 23.4% and Sunday at 21.2%. 

Black Friday came in fourth at 17.3%, during Small Business Saturday was the quietest day at 11.5%.

The allocation suggests that many senders dispersed their campaigns throughout the week fairly than concentrating quantity on Black Friday itself. And the inbox was really additional crowded on Cyber Monday.

Best hr to send: The busiest windows were never the finest ones

The data shows that the hours whenever the most emails were sent tended to have the lowest open rates.

The four busiest shipment hours, classified by quantity – 12:00, 07:00, 13:00, and 21:00 UTC – accounted for concerning 31% of the week’s emails, but none had an open charge complete 22%.

The better-performing hours came exterior this group. 08:00 UTC had the highest open charge at 32.0%, during 15:00 UTC stood out for the two opens and clicks, alongside a 31.1% open charge and a 2.9% click-through rate. 

Additionally, open rates topped 25% at 10:00, 16:00, and 20:00 UTC.

Lower quantity wasn’t a justify of powerful achievement – a few quiescent hours underperformed, too. But throughout the busiest hours specifically, none exceeded 22%, which was the clearer and additional accordant signal.

The data doesn’t inform us exactly why this form occurs. One imaginable clarification is inbox competition: whenever small senders are sending at the identical time, idiosyncratic emails may have additional area to get noticed.

How the finest sending hr shifts by day

The strongest sending opening didn’t remain fixed throughout the week. There’s a apparent split: midday to mid-afternoon on operating days, and dawn on weekends.

On weekdays, the form was fairly consistent. 

Thursday performed finest at  12:00 UTC, alongside a 28.3% open charge and 2.9% CTR, although this particular hr motionless averaged below 22% for the week overall. 

Friday and Cyber Monday the two peaked at 15:00 UTC, alongside a 30.6% open charge on Friday and a 28.1% open charge and 3.4% CTR on Cyber Monday.

The weekend shifted the opening earlier. Saturday’s finest hr was 09:00 UTC; Sunday’s was 08:00 UTC, alongside a 27.8% open charge and 3.1% CTR.

Saturday is value noting in isolation. It was the lowest-sending day of the week, and equal its finest hr saw fair a 15.5% open charge and 0.9% CTR – approximately fractional the open charge of the weekday peaks. The data doesn’t propose that sending additional on Saturday would guide to stronger results – it was a quieter day in the two quantity and performance.

Opens and clicks don’t continually highest at the identical time

Our data shows that the hr whenever group are most apt to open the Black Friday emails isn’t necessarily the hr whenever they’re most apt to take action.

On Black Friday, 15:00 UTC had the highest open charge at 30.6%, but its CTR was fair 1.5%. Clicks peaked at 22:00 UTC, alongside a 4.0% CTR. 

In another words, the hr that drove the most opens wasn’t the hr that drove the most clicks.

Attentive’s 2025 BFCM inspection of 2.07 milliard email sends from 217 US retailing brands established a akin form at scale. Its strongest involvement and conversion windows occurred at distinct times, and the two varied from day to day.

That difference matters whenever deciding what you desire your dispatch to achieve. 

If opens are the priority, dawn windows may be value testing. If clicks or conversions matter more, the optimal opening may change – and can change by day.

How Hostinger Reach’s data findings difference to another sources

Reach’s findings sit inside a broader landscape of BFCM timing research, and the assortment throughout sources helps explain why there’s no sole worldwide answer.

Klaviyo’s data from Black Friday 2024 identified 9–10 a.m. ET is the busiest sending hour, alongside additional than 420 myriad messages sent in that window. Peak command quantity followed at noon–1 pm ET.

Do note that Klaviyo’s sender basis skews additional toward the US, during Reach’s skews additional toward Europe, so the two indicate distinct audiences fairly than contradicting all other.

Omnisend’s Black Friday-specific guide recommends 6–9 a.m. or 8–10 p.m., noting that these windows lean to outperform midday sends. 

SiteGround Academy names Friday mornings before 8 a.m. as the sole finest time, without citing supporting data. And the acquainted direction to dispatch on Tuesday comes from broad email promotion benchmarks, not item particular to Cyber Week.

The assortment isn’t surprising, as each dataset reflects a distinct sender population, period period, and measure method. 

That’s why the most helpful understanding from these articles isn’t a worldwide “best time.” Instead, you need to appearance at how distinct audiences behave, afterward use the data closest to your own spectators as a starting point.

How to use these insights to your Black Friday campaign

None of these datasets, Reach’s included, have to be treated as a fixed agenda to copy. The additional helpful method is to treat the findings as hypotheses to test against your own audience.

Here’s what Hostinger Reach’s data suggests as a starting example to decide on your finest period to dispatch Black Friday emails:

• Skip the crowded hours. The data consistently showed that the busiest sending windows had the weakest engagement. If you’re choosing between a highest hr and one slightly before or later, the small crowded choice is value evaluation first.
• Adjust by day. Reach saw stronger involvement about midday to mid-afternoon on weekdays, and in the dawn on weekends. Map that form to your audience’s local period area fairly than copying the UTC hours directly.
• Separate your goals. If email open charge matters most to you, the data mostly points to dawn windows. If clicks and conversions are the priority, appearance at what happened afterward in the day – and test accordingly.
• Don’t equate dispatch quantity alongside acquisition intent. Cyber Monday led in the two email dispatch quantity and revenue during Cyber Week 2025 – accounting for 32.2% of Cyber Week revenue compared to Black Friday’s 26.7% – but the gap is decision year-on-year, according to latest Black Friday statistics. So, spreading your run throughout the week is a safer bet than concentrating everything on one day.
• Use your own data to calibrate. Audience, geography, industry, and run category all power whenever group engage. Reach’s findings provision you a starting assumption – your own catalog gives you the answer.

Ultimately, dispatch timing is one of multiple inputs. List quality, recommendation strength, and deliverability all perform important roles in determining whether an email performs, despite of whenever it lands.
