There is no best time to send

In today's Mailbites, we talk about send-time optimization, the endless hunt for the perfect moment to hit send, and why the famous "best time to email" is one of the most confidently repeated myths in marketing.

Now, onto today's story.

The Story

Search "best time to send email" and you'll get a tidy answer: Tuesday, 10am. Or Thursday, 8am. Or whenever the latest study of fourteen billion emails decided. These charts are everywhere, they look authoritative, and they're close to useless for you specifically.

Here's the problem. Those studies average across every industry, every audience, every time zone on earth. The result is a number that describes nobody. Your customers aren't the global average. They're new parents who check their phone at 5am, or office workers who triage email at lunch, or night-owl shoppers who buy at 11pm. The "best time" is a property of your list, not of the calendar, and no industry chart knows your list.

There's a deeper issue, too. Even your own data lies to you here, because of how opens are now counted. A big slice of "opens" are machines preloading your email at whatever time the mailbox provider feels like, not when a human read it. So when you optimize send time based on open timestamps, you're often tuning to a robot's schedule, not your customer's habits. You can chase that ghost for months and learn nothing.

So what actually matters? A few things, and none of them is a magic minute.

• Consistency beats precision. A predictable cadence, the same kind of email at roughly the same time, trains your audience to expect you and builds the sending reputation that gets you to the inbox in the first place. That's worth more than shaving an hour off your send.
• Relevance beats timing. A genuinely useful email opened at 4pm beats a dull one opened at the "optimal" 10am. People open things they want whenever they find them.
• Your own behaviour beats benchmarks. If you must optimize, test send times on your real list and judge by clicks and revenue, not opens. Let your customers, not a study, tell you when they buy.

Stop hunting for the universal perfect moment. It doesn't exist, and the search distracts from the things that genuinely move the needle: sending something worth opening, to people who want it, on a rhythm they can rely on.

Until next week,
