The best time to send an email on Friday is usually between 9:00 a.m. and 11:00 a.m. in the recipient’s local time zone, with 10:00 a.m. being the safest starting point. If your audience is B2B, aim earlier in that window. If your list is consumer focused, lunchtime can still work, especially for retail, events, restaurants, and weekend offers. Between Mailchimp and HubSpot, Mailchimp is easier for quick send time testing, while HubSpot is stronger when timing is tied to CRM data, buyer behavior, and segmented journeys.
TLDR: For most Friday campaigns, start with 10:00 a.m. local time, then let your email platform refine the timing. For example, a SaaS newsletter sent at 10:00 a.m. on Friday may see a 22% open rate, while the same email at 3:30 p.m. may drop to 15% because people are wrapping up the week. Mailchimp is better if you want a simple recommendation fast. HubSpot is better if you want send timing connected to lifecycle stage, sales activity, and past engagement.
Why Friday Email Timing Is Tricky
Friday is not a bad email day. It is just less forgiving.
People check their inbox in the morning, clear urgent items, and then mentally shift toward the weekend. By mid afternoon, attention drops. That makes timing matter more than usual. A strong subject line sent at 10:00 a.m. can win attention. The same message at 4:15 p.m. may sit unread until Monday, buried under newer mail.
For Friday, the goal is simple: arrive after the first coffee, but before the weekend brain takes over.
Best Friday Send Times by Audience Type
There is no magic hour for every list. Still, these windows are a smart baseline:
- B2B newsletters: 9:00 a.m. to 10:30 a.m.
- Sales follow ups: 8:30 a.m. to 10:00 a.m.
- Ecommerce promotions: 10:00 a.m. to 1:00 p.m.
- Restaurant, entertainment, and local events: 11:00 a.m. to 2:00 p.m.
- Weekend flash sales: 12:00 p.m. to 3:00 p.m., but test carefully
Late Friday can work for urgent consumer offers, but it is risky. If the email needs thought, approval, or a business decision, avoid the end of the day. Honestly, it feels like sending a proposal at 4:45 p.m. on Friday is just asking it to be forgotten.
Mailchimp Send Time Optimization on Friday
Mailchimp is popular because it keeps email scheduling simple. Its send time optimization feature uses subscriber engagement data to suggest a better send time. For teams that do not want to study dashboards for an hour, this is useful.
You choose your campaign, pick send time optimization if it is available on your plan, and Mailchimp recommends a time based on previous activity. For a Friday campaign, that can save you from guessing between 9:00 a.m., 10:00 a.m., or noon.
Where Mailchimp Works Well
- Simple newsletters: Great for weekly updates and content roundups.
- Small teams: Less setup and fewer technical steps.
- General list behavior: Useful when you have enough past engagement data.
- Fast testing: Easy to compare Friday morning against another weekday.
The annoying part is that Mailchimp’s recommendation can feel a little too broad. If your list includes CEOs, students, retail shoppers, and inactive subscribers, one suggested time may not mean much. You still need segmentation. Otherwise, you are averaging people who behave nothing alike.
HubSpot Send Time Optimization on Friday
HubSpot is better when email timing is part of a wider marketing and sales system. It connects email performance with contact records, lifecycle stages, deal activity, website behavior, and workflow history. That gives you more context than a basic campaign report.
Depending on your HubSpot tier and available features, you can use tools such as time zone sending, workflow timing, A/B testing, engagement reporting, and predictive or AI assisted recommendations where available. The real strength is not just picking “Friday at 10.” It is deciding who should get the email, why they should get it, and when it fits their buyer stage.
Where HubSpot Works Well
- B2B nurturing: Strong for leads moving through a sales funnel.
- Segmented timing: Send based on persona, region, activity, or lifecycle stage.
- Sales alignment: Avoid sending campaigns right after a rep logs a sensitive call.
- Workflow control: Better for automated sequences than one off blasts.
The frustration? HubSpot can take longer to set up. A basic timing test that takes a few minutes in Mailchimp may take more planning in HubSpot if you are building lists, rules, and workflow branches. The payoff is better control, but you need clean data.
Mailchimp vs HubSpot: Which Is Better for Friday?
The answer depends on your campaign type.
| Use Case | Better Choice | Why |
|---|---|---|
| Weekly newsletter | Mailchimp | Fast setup and simple send time guidance. |
| B2B lead nurturing | HubSpot | Better contact data and workflow timing. |
| Small ecommerce promo | Mailchimp | Easy testing and quick scheduling. |
| Sales cycle emails | HubSpot | CRM activity helps prevent awkward timing. |
| Global audience | HubSpot | Stronger segmentation if your data is organized. |
If you just need to send a Friday newsletter, Mailchimp is usually enough. If your Friday email is tied to revenue, sales calls, demos, renewals, or account status, HubSpot gives you more room to be precise.
A Practical Friday Testing Plan
Do not trust general benchmarks forever. Use them as a starting point, then test your own list. A clean four week test can teach you more than a dozen generic reports.
- Week 1: Send Friday at 9:00 a.m.
- Week 2: Send Friday at 10:00 a.m.
- Week 3: Send Friday at 12:00 p.m.
- Week 4: Send Friday at 2:00 p.m.
Track more than opens. Apple Mail Privacy Protection and similar features can blur open rate data. Watch click rate, reply rate, conversion rate, unsubscribe rate, and revenue per recipient. A send time with fewer opens but more purchases may be the better time.
Example: Friday Timing in Action
Say a software company sends a Friday email to 18,000 trial users. It tests three send times over several campaigns:
- 9:00 a.m.: 24% open rate, 3.8% click rate
- 11:30 a.m.: 21% open rate, 4.4% click rate
- 3:00 p.m.: 16% open rate, 2.1% click rate
The 11:30 a.m. send wins on clicks, even though opens are lower. That suggests users may be checking email near lunch and taking more time to act. If that company used Mailchimp, it might set Friday late morning as the preferred window. If it used HubSpot, it could split users by trial stage and send upgrade nudges to highly active users earlier.
Common Friday Email Mistakes
- Sending too late: After 3:00 p.m., attention often fades.
- Ignoring time zones: 10:00 a.m. in New York is not 10:00 a.m. in Los Angeles.
- Using one time for every segment: Buyers, readers, and trial users behave differently.
- Judging only by opens: Clicks and sales matter more.
- Testing during holidays: Friday before a long weekend can distort results.
Final Recommendation
For most brands, send Friday emails between 9:00 a.m. and 11:00 a.m. local time. Start at 10:00 a.m. if you have no data. Move earlier for B2B decision makers. Try lunch for ecommerce, food, events, and weekend promotions.
Choose Mailchimp if you want quick scheduling, simple testing, and easy recommendations. Choose HubSpot if email timing needs to connect with CRM data, sales activity, and segmented automation. The best tool is the one that helps you stop guessing and start matching send time to real subscriber behavior.
