Best Time to Send Email on Thursday (2026 Data)

Every "best day to send email" article recycles the same Tuesday-morning advice and ignores the day you actually care about. Thursday-specific data is buried in generic guides - if it shows up at all. You need the best time to send email on Thursday, backed by real numbers. Here they are.

Quick Answer: Three Thursday Windows

If you need a number right now:

  • For clicks: 8 AM. A 2.1M-campaign study found Thursday clicks peak at 8 AM - a pattern unique among weekdays.
  • For opens: 8-11 AM, with 9-11 AM as the strongest sub-window. This lines up with peak-open patterns across most weekdays.
  • For B2C promos: 2-4 PM or 8 PM. Afternoon peaks and evening engagement both support this.

Thursday is the most popular send day among marketers, though, which means the most crowded inbox. Keep reading for the workaround.

The Thursday Paradox

Here's the thing: Thursday is the most favored send day across major ESP datasets. Friday and Wednesday trail behind. Every time you follow "send on Thursday" advice, you're competing with everyone else who read the same article.

EmailOpShop calls this the self-defeating best time. If everyone sends at the "optimal" window, inbox competition spikes and the advantage evaporates. This competition effect has been discussed for over a decade - a MarketingCharts summary of a MailerMailer report based on 1.4B emails found that while recipients were most likely to open around 10 AM, scheduled sends during business hours actually performed worse, consistent with heavier inbox competition when everyone piles in at the same time. Some practitioners deliberately avoid peak days entirely for this reason.

The workaround isn't to avoid Thursday. It's to be smarter about when on Thursday you hit send.

Hour-by-Hour Thursday Email Performance

Window Best For Source Tactic
8 AM Clicks 2.1M-campaign study Send a few minutes before or after the hour to dodge the biggest pileups
9-11 AM Opens MailerLite + Mailjet + practitioner examples Default B2B window
2-4 PM Opens + clicks Brevo afternoon peak around 3:30-4:00; Omnisend recommends 2 PM Post-lunch dip; newsletters
5-8 PM B2C engagement + conversions Omnisend recommends 5 PM or 8 PM Ecommerce promos

The 8 AM click anomaly is the lead insight. On most other weekdays, clicks peak in the evening around 8-9 PM. Thursday breaks the pattern - people who open at 8 AM act immediately instead of saving it for later. Unlike Friday, where opens and clicks conveniently peak together around 6 PM, Thursday forces you to pick your optimization goal.

Mailjet's data suggests emails sent between 6-8 AM are half as likely to be read immediately. Thursday is the exception.

We've tested scheduling sends at :07 or :53 instead of :00. Even without changing your content, sending slightly off the obvious top-of-the-hour slot helps you avoid the noisiest minute in the inbox. Zero-cost edge.

Brevo's data also shows that opens and clicks don't always align by hour, which is why optimizing for clicks matters more than chasing opens.

For timezone math: Sinch Mailgun's 15:00 UTC peak translates to 11 AM Eastern in summer and 8 AM Pacific. For coast-to-coast US coverage during work hours, 12 PM ET / 9 AM PT is a clean default.

If you’re applying this to outbound, the best time to send cold emails has a few extra constraints (reply windows, follow-ups, and deliverability).

Thursday Performance by Industry

Klaviyo's benchmark data breaks Thursday performance by vertical:

Thursday email performance comparison across industries
Thursday email performance comparison across industries
Industry Thu Open Rate Thu Click Rate Thu Order Rate Verdict
Food & beverage - - 0.61% (best day) Thursday is your day
Jewelry 11.20% (best) 1.92% (best) - Thursday wins engagement
General ecommerce 12.43% 2.13% 0.22% Competitive with Tue/Wed

Omnisend puts Thursday's overall open rate at 11.29% versus Tuesday's 11.36%. The gap is negligible. If you're in food & beverage or jewelry, Thursday isn't just competitive - it's your strongest send day by a meaningful margin.

B2B vs B2C: Different Thursdays

Thursday morning for B2B. The heuristic for coast-to-coast coverage is 12 PM ET / 9 AM PT to 5 PM ET / 2 PM PT. For single-timezone lists, 9-11 AM local time is the sweet spot. We've found this window consistently outperforms afternoon sends for decision-maker engagement in our own outbound campaigns. (If you’re building a repeatable outbound motion, pair timing with sales prospecting techniques that keep reply rates stable.)

Thursday evening for B2C. Omnisend's recommended send times include 5 PM and 8 PM, which lines up with after-work browsing on personal devices - a strong slot for ecommerce promos and flash sales.

One thing to watch: Apple Mail Privacy Protection inflates open rates. If a big chunk of your list uses Apple Mail, optimize for clicks and conversions instead. Opens aren't telling you the truth. To keep reporting honest, use a consistent click rate formula across campaigns.

Find Your Own Thursday Sweet Spot

Benchmarks give you a starting point. Your own data gives you the answer.

Check your ESP's historical Thursday data. Sort by click rate, not opens. Clicks reflect genuine engagement; opens are polluted by Apple MPP and prefetching. Most ESPs let you filter performance by day of week - if yours doesn't, export the last 90 days and run a quick pivot table.

Run one A/B test. Split your Thursday list between 9 AM and 2 PM for four consecutive weeks. That's enough signal to see a real pattern, and it costs you nothing beyond the setup time. If you want to push lift further, test email subject lines alongside send time.

Use send-time optimization if available. Mailchimp, Brevo, and Klaviyo all offer per-subscriber delivery timing. Let the algorithm do the work once you've exhausted manual testing.

Your website traffic data works as a proxy, too. If analytics show a Thursday traffic spike at 11 AM, that's when your audience is active and ready to click.

The Part Nobody Mentions: List Quality

Let's be honest - send timing matters, but list quality matters more. Teams obsess over whether to send at 9 AM or 2 PM on Thursday while a big chunk of their addresses bounce. That tanks sender reputation faster than any scheduling mistake ever will. (If you’re troubleshooting this, start with email bounce rate benchmarks and root causes.)

We've seen teams nail their Thursday timing, hit a 12% bounce rate because of stale data, and watch their domain reputation crater in a single campaign. All that optimization work, wasted. If you're running outbound at any real volume, verifying your list before every major send isn't optional - it's the baseline. A full email deliverability guide can help you fix the rest of the stack too (SPF/DKIM/DMARC, warming, and complaint rates).

Prospeo's free tier gives you 75 email verifications per month, enough to audit your next Thursday campaign before you hit send.

Prospeo

Thursday inbox competition is brutal - every marketer read the same "best day" advice. The edge isn't just timing at 8 AM or 2 PM. It's reaching verified, real inboxes while your competitors bounce off stale data. Prospeo's 7-day data refresh means you're never sending to addresses that went dead last month.

Stop optimizing send times on a dirty list. Fix the data first.

Frequently Asked Questions

Is Thursday better than Tuesday for email?

Nearly identical. Omnisend puts Tuesday at 11.36% opens versus Thursday at 11.29%. Klaviyo shows Thursday at 12.43% versus Tuesday at 12.52%. Pick based on your audience, but know Thursday has more inbox competition since it's the most popular send day among marketers.

Should I send Thursday morning or afternoon?

Morning (8-11 AM, especially 9-11 AM) wins for open rates. Afternoon (2-4 PM) is strong for newsletters and content-heavy sends. For clicks specifically, 8 AM on Thursdays outperforms every other hour - a pattern unique to that day.

Does Thursday email timing differ for B2B and B2C?

Yes. B2B emails perform best Thursday morning in the recipient's time zone, typically 9-11 AM local. B2C promos do well later - especially around 5 PM or 8 PM when people browse personal devices. Skip the evening window entirely if you're selling to enterprise buyers; they're not checking work email at 8 PM.

How do I make sure my Thursday emails actually get delivered?

Timing is irrelevant if your emails bounce. Verify your contact list before every major send - a single campaign with a high bounce rate can damage your sender reputation for weeks. Even a quick spot-check of 50-75 addresses catches the worst offenders before they hurt you.
