How often should you actually email your list?

Search this question and you get the same answer everywhere: email two to three times a week. It's not wrong exactly. Most stores land somewhere in that range. But it's a starting guess dressed up as a rule, and treating it like a rule is how you end up either too quiet to matter or so loud you train people to tune you out.

Here's what the generic advice misses. The real cost of getting frequency wrong runs in both directions. Email too little and you're invisible. The list goes cold, people forget they signed up, and when you finally do send something they mark it as spam because they don't recognize you. Email too much with nothing to say and you exhaust the list, unsubscribes climb, and your deliverability starts to slip for everyone.

So the honest answer isn't a number. It's a question you ask of your own data.

Why more is usually the answer, up to a point

Most owners email less than they should, out of a fear of being annoying. The data rarely backs the fear. Industry studies have found that lists moved from two sends a week to three saw roughly 43% more opens in aggregate, with a similar bump in revenue. Not because each email got better. Because more at-bats means more chances to catch someone at the moment they're ready.

That's the mental shift. An email isn't an interruption you're rationing. It's a chance for the right person to buy at the right time. You don't know which send lands for which subscriber, so within reason, more sends means more of those moments captured. The store emailing three times a week almost always beats the identical store emailing twice, and they're often shocked the extra send didn't cost them anything.

The signals that tell you you've gone too far

There is a ceiling, and your list will tell you where it is. Watch three things, not the calendar.

Revenue per email. This is the one that matters most. Total email revenue divided by emails sent. If you add a send and total revenue goes up, keep it, even if each individual email earns a little less. If adding sends actually drops your total, you've passed the point of more.

Unsubscribes and spam complaints. A small, steady unsubscribe rate is healthy list hygiene. A spike right after you increase frequency is the list telling you to ease off. Complaints are the louder version of the same message and they hurt deliverability, so weight them heavily.

Engagement trend, not any single open. If opens and clicks are sliding week over week as you send more, you're wearing the list out. If they hold steady while you send more, you have room to keep going.

The part nobody tells you: it depends on what you sell

Frequency isn't one-size. A fashion or food brand with something new to say constantly can email most days and stay welcome. A considered, once-a-year purchase should send far less or it feels like nagging about a decision the customer already made. Higher purchase frequency and lower price usually means you can email more. The opposite means email less and make each one count.

And it's not just campaigns. Your automated flows, the welcome, the cart reminder, the post-purchase, are also "emails your subscriber gets from you." A well-built set of flows does a lot of the talking, which means your broadcast frequency can be lower and still keep the relationship warm.

How I'd actually set it

Start where the list is. If you email once a month, don't jump to daily. Ramp gradually, a send at a time, and watch the three signals for a couple of weeks before adding another. Segment out the people who never engage so you're not counting them, they drag your averages down and your deliverability with them. Then push frequency up until revenue per email or complaints tell you to stop. That number, the one your own list gives you, is worth more than any benchmark.

The goal was never to hit a magic cadence. It's to send as often as the list will happily pay for, and no more.

Frequency is one piece of a system that includes your flows, your segments, and your deliverability. If your email is underperforming and you're not sure whether it's frequency, targeting, or the offer, that's exactly what I diagnose. See why follow-up beats chasing new leads, or book a call and I'll tell you where your email is leaking.

Common questions

How many marketing emails per week is too many?

There's no universal number. You've sent too many when your revenue per email drops, or when unsubscribes and spam complaints spike after you increase frequency. Until those turn, more sends usually means more revenue, not less.

Will emailing more often hurt my deliverability?

Only if you're emailing people who don't engage. Blasting inactive subscribers hurts inbox placement for everyone on your list. Email your engaged segment more often and prune the dead weight, and higher frequency is safe. That's the trap I break down in why batch-and-blast is killing your list.

How often should a small or service business email its list?

Less often than a high-frequency ecommerce store, but at least once a month so the list doesn't forget you. Consistency matters more than volume, and a good set of automated flows keeps the relationship warm between your broadcasts. If you're wondering whether it's even worth the effort, see whether email marketing is still worth it.
