You know that voice in your head that says you’ll annoy people if you email them again this week? That one quiet worry is costing you more than any unsubscribe ever will.
Most product founders I meet are sending too few emails, not too many. They’ve been told sending more is spammy, so they sit on a list of thousands and send once a fortnight, if that. Then they wonder why email barely shows up in the revenue report.
Here’s the thing. When you send with intent, more emails make more money. I watched it happen in real time on an account this month, and the number on the screen was hard to argue with.
Quick answer: how often should you send marketing emails?
For most established ecommerce brands, two to four campaigns a week is the right starting range, not one a fortnight. The brands that send more (with a real reason behind each send) consistently pull more revenue from email. One brand we manage increased its sending cadence and email jumped to 32% of attributed revenue. The cap is relevance, not a magic number.
Does sending more emails actually make more money?
Short version: yes, when each email earns its spot in the inbox.
I pulled a 30-day report for one brand recently and kept refreshing it because the trend would not quit. Email attributed revenue (the sales Klaviyo can directly tie back to an email) had climbed to 32% of the brand’s total. The single biggest lever? We were simply sending more campaigns.
Email should be doing 25 to 40% of your revenue. Most brands I see are sitting around 12%, and almost always the gap is frequency. They have the list. They have the products. They’re just not showing up in the inbox often enough to be remembered.
This is the part that trips people up. Every campaign you don’t send is a sale you quietly hand to whoever did email that day. Your list doesn’t sit in suspended animation waiting for you. It moves on.
Won’t I annoy my list if I email more often?
You will annoy your list if you email them without a reason. That’s different from emailing them often.
The fear of being annoying usually comes from picturing the same tired “10% off, shop now” email landing every second day. Of course that gets old. Nobody wants that.
The fix isn’t fewer emails. It’s giving every email a theme. When each send has a genuine hook, a reason to exist, frequency stops feeling like noise and starts feeling like a brand that has something going on.
Think about the brands you actually open. They’re not quiet. They’re just interesting.
How do you give every email a reason to exist?
This is where a campaign calendar earns its keep. Instead of sitting down each week thinking “ugh, what do I send now,” you map the month around real moments and let each one carry an email.
Look at any single month and you’ll find more hooks than you think. A cultural moment. A seasonal event. A brand birthday or milestone. A new range. A behind-the-scenes story about how a product is made or who designs it. Each of those is a themed email, and not one of them is “buy my stuff for no reason.”
When I plan a month for a brand, I’m not asking “what are we writing next.” I’m asking “what’s worth talking about,” then matching a send to each answer. The writing gets easier and the results get better, because intent does the heavy lifting.
A quick gut check for any send: if you can’t say in one line why this email is landing today, it’s not ready. Give it a reason or move it.

How do you run a sale that rewards your list instead of training discounts?
More sending only works if you’re not torching your margin every time. The trick is making your email list feel like the place to be, without giving the whole world your best offer.
Here’s a structure that works well for a birthday, an anniversary or any list-only moment. Tier the offer so loyalty is actually rewarded:
- Everyone on the list gets the entry-level perk (free shipping is a strong one, because it feels generous without gutting margin).
- Repeat buyers and VIPs get the real prize on top (a deeper discount on the products they’ve been waiting for).
- Keep your loss-leader items VIP-only so the products with thin margins aren’t handed to one-time bargain hunters.
Then run it as a short window. A 24-hour sale creates real urgency because it’s true, not because you invented a fake countdown. If a 24-hour birthday sale worked last time, you already have your answer for next time. If it isn’t broke, don’t fix it.
The bonus play: announce the sale a week out and use it to grow the list. A simple “get on the list by [date] to access this” campaign, organic or paid, turns your sale into a list-building moment as well as a revenue one. New subscribers come in warm, right before you make an offer.
Should you put a delivery cutoff date in your emails?
Only if you can actually honour it. This one matters more than founders realise.
It’s tempting to slap “order by the 11th to get it in time” on a holiday campaign. It creates urgency, sure. But if your shipping times are unpredictable (and for a lot of brands shipping internationally, they are), a hard date you can’t guarantee sets you up for refund requests, angry replies and a customer who doesn’t trust you next time.
The better move is honest urgency. Swap the fake-precise date for “order now for your best chance to receive by [event],” and add a quiet line that delivery times aren’t guaranteed. You still get the nudge to buy now. You just don’t promise something the courier might not deliver.
Fake urgency is a short-term win and a long-term trust leak. We don’t do it, and neither should you.
How does sending more help your automated flows too?
Here’s a bonus that surprises people. The insights you get from sending more campaigns make your automated flows (the abandoned cart, browse abandonment and welcome series that run in the background) smarter too.
One example. A founder told me a huge chunk of her customers couldn’t find products they actually wanted because they didn’t know how to use the site filters. People literally asked for things she already sold.
That’s a campaign idea (a “how to find your perfect [product]” email), and it’s also a flow upgrade. Drop that same “here’s how to search our range” content into the welcome series, the browse abandonment flow and the win-back flow, and you’re rescuing sales on autopilot from people who were ready to buy but got stuck.
Campaigns teach you what your customers are confused about. Flows let you fix it once and benefit forever.
Key takeaways
- More emails make more money when each one has a real reason to exist. One brand reached 32% of attributed revenue mainly by sending more.
- Two to four campaigns a week is a healthier starting range than once a fortnight for most established brands.
- Frequency isn’t the thing that annoys people. Pointless emails are. Give every send a theme.
- Plan the month around real moments so writing gets easier and every email carries intent.
- Tier your sales so your list and your VIPs feel rewarded and your margin survives.
- Skip cutoff dates you can’t honour. Use honest urgency instead.
- Campaign insights upgrade your flows, so the lessons keep paying off in the background.
FAQ
How often should an ecommerce brand send marketing emails?
For most established brands with a list of 3,000 or more, two to four campaigns a week is a solid range. The right number is set by how much you genuinely have to say, not by a fixed rule. If every send has a clear theme, you can send more without wearing out your list.
What percentage of revenue should email drive?
Email should be doing 25 to 40% of your total revenue. Most brands sit closer to 12%, and the gap is almost always too few campaigns plus under-built automated flows.
Will sending more emails increase unsubscribes?
A few more unsubscribes can happen, and that’s fine. People who were never going to buy leaving your list is healthy. What matters is revenue per send and total revenue, both of which usually climb when you send relevant campaigns more often.
How do I come up with enough email topics to send more often?
Build a monthly calendar around real moments: seasonal events, cultural dates, brand milestones, new ranges, customer questions and behind-the-scenes stories. Map a theme to each, and the “what do I send” problem disappears.
Should I use a delivery cutoff date for holiday sales?
Only if you can reliably meet it. If shipping times are unpredictable, use “order now for your best chance to receive by [date]” with a note that delivery isn’t guaranteed. It keeps the urgency without the broken promise.
The simplest way to send more without it eating your week
If you read all that and thought “great, but I do not have time to plan and write two to four themed emails a week,” that’s the honest catch. Sending more only works when it’s done well, and done well takes time you probably don’t have.
That’s exactly what we take off your plate. In Flow Marketing runs done-for-you Klaviyo email for established product brands, the strategy, the calendar, the copy, the design and the optimisation, so the right emails go out at the right cadence and you just watch the report. In 2025 the brands we manage made $2.5 million from email.
