Anastasia Braitsik has built a career at the intersection of data science and consumer psychology, helping brands navigate the increasingly crowded digital landscape. As a global leader in SEO and data analytics, she understands that successful email marketing is no longer about just hitting “send,” but about mastering the invisible rhythms of the recipient’s day. In an era where attention is the most valuable currency, her insights provide a roadmap for marketers looking to cut through the noise with surgical precision.
This conversation explores the evolving science of email delivery, moving beyond simple scheduling to examine the deep metrics that drive genuine engagement. We delve into why the traditional morning window remains a powerhouse for visibility while uncovering the specific hours that actually trigger sales and conversions. Anastasia also addresses the critical impact of modern privacy features on data accuracy and provides a framework for rigorous testing that allows brands to build a strategy unique to their own audience’s behavior.
The 9 AM to 11 AM window has long been considered the “golden hour” for reaching subscribers. Based on the massive datasets we see today, does this timeframe still hold its crown for reliability?
When we look at the sheer scale of the data, specifically the Omnisend study covering about 26 billion emails, the 9 AM to 11 AM window remains incredibly resilient for sheer visibility. There is a psychological comfort in that morning slot; it’s when people are settling into their workspaces, perhaps sipping their first coffee, and clearing out the clutter. However, while it is the most reliable for opens, we have to treat it as a foundational starting point rather than a universal law. I always tell my clients that while you might get the “eyeballs” during this time, the actual “action” might be happening elsewhere depending on the specific nature of your offer. You have to balance that morning peak with the reality that every list has its own unique heartbeat that might defy these broader averages.
We often see a disconnect between when people open an email and when they actually click through. How should marketers navigate these different peaks to ensure they aren’t just being seen, but are being heard?
This is where the data gets truly fascinating because the peaks for opens and clicks rarely happen in the same breath. In recent findings, we’ve seen clicks hit their highest points quite early, around 7 AM to 8 AM, and then again during a late-afternoon surge near 4 PM. It’s almost as if subscribers are doing a quick triage in the morning and then returning to take action when they have more breathing room later in the day. The urgency is real, too, considering that 44.14% of all clicks happen within the very first hour of a message hitting the inbox. If you miss that initial window of intent, you’re relying on the remaining 15% of click activity that trickles in after the first 24 hours, which is a much harder hill to climb.
There is a lot of discussion regarding the reliability of open rates now that privacy features have become standard. How much weight should we still be giving to “open” data in 2026?
We have to be extremely cautious with open rates because features like Apple’s Mail Privacy Protection have fundamentally changed the landscape by triggering automated opens that don’t reflect actual human engagement. This creates a “phantom” open rate that can lead marketers to believe their content is performing better than it actually is. Because of this distortion, I’ve shifted my focus almost entirely toward clicks and conversion metrics as the surer signs of life. When you realize that about 70% of opens might be registered within the first day, but those numbers are inflated by background downloads, the click-through rate becomes your only true North Star. It’s the difference between someone glancing at a storefront and someone actually walking through the door and picking up a product.
When planning a weekly calendar, many teams default to a midweek schedule. Is there a genuine statistical advantage to Tuesday over the rest of the week?
Midweek is definitely the “power zone” for engagement, with Tuesday often leading the pack for both opens and clicks across various studies, including data from Sinch Mailgun. There’s a certain momentum that builds from Tuesday to Thursday once the “Monday rush” has subsided and people are fully immersed in their routines. That said, the gap between the best and worst days for opens can be surprisingly narrow—sometimes as small as 1.6 percentage points. What’s more interesting is how the goal changes by the end of the week; for instance, Friday often sees a major spike in sales. Friday at 7 AM has shown the highest conversion rates, suggesting that while people might be opening fewer emails as the weekend approaches, they are much more ready to spend money when they do.
Different types of content clearly serve different purposes. How do you adjust your timing strategy when switching between a regular newsletter and a high-stakes product launch?
The strategy has to be entirely goal-dependent because a newsletter is a marathon of brand-building, whereas a sales email is a sprint for revenue. For a newsletter, you want those Tuesday or Wednesday morning slots, specifically between 9 AM and 11 AM, to maximize the chances of being read during a calm moment. Sales emails, however, need to catch the subscriber when they are in a “buying” headspace, which often means testing early morning sends against late afternoon windows. I recommend running a direct comparison: send your launch announcement at 7 AM to catch the early risers and then try a different segment at 5 PM or 7 PM. By analyzing which slot earns more money rather than just more opens, you can tailor your next big campaign around actual profit rather than just digital “noise.”
Business-to-business marketing often feels like a different world compared to consumer-facing campaigns. What specific timing nuances should B2B professionals keep in mind?
In the B2B sector, you are essentially trying to catch a professional in the middle of their productivity flow, which makes the working day your primary theater of operations. We’ve found that the best window for cold B2B outreach is typically Tuesday through Thursday, specifically from 8 AM to 10 AM, right after they’ve cleared the initial hurdle of their morning meetings. You also have to be much more mindful of the regulatory environment, especially under UK rules and the updated ICO guidance following the Data Use and Access Act. For individuals and sole traders, you need specific consent, whereas for corporate entities, the rules are slightly different, but the principle of providing a clear opt-out remains universal. Timing your B2B sends separately from B2C is vital because a business subscriber’s inbox behavior is dictated by their professional obligations, not their personal whims.
For a brand that wants to move away from generic industry benchmarks, what is the most effective way to identify their own “perfect” send time?
The only way to find your “perfect” time is through rigorous, repeated split testing on your own list. I suggest taking your audience and splitting them into two random, equal groups to test two different hours—say, a 9 AM send versus a 4 PM send—while keeping the content identical. You can’t just do this once and call it a day; you need to repeat this over three to five different campaigns to ensure one anomalous day doesn’t skew your entire strategy. It is also essential to segment your subscribers by location because a 9 AM send time in New York is the middle of the night for a subscriber in London. Once you have those statistics, you can use scheduling tools like Ubivox to automate the process, but always keep an eye on those click-through patterns to see if your window of opportunity is shifting over time.
What is your forecast for the future of email marketing strategy?
I believe we are moving toward a “quality over frequency” era where technical authentication and brand recognition will matter far more than the exact minute an email is sent. As filters become more sophisticated, sending from your own authenticated domain isn’t just a recommendation anymore—it’s a requirement for survival. We will see a shift where the sender’s reputation and the recognizability of the brand become the primary drivers of the “open,” rather than the subject line or the timing. My forecast is that the most successful marketers will be those who stop trying to “hack” the clock and start focusing on building a domain reputation so strong that their subscribers will go looking for their emails, regardless of what time they arrive. Success will be defined by being a welcome guest in the inbox, not just a well-timed intruder.
