You're planning next month. There's a new product dropping on the 18th. There's also a sitewide promo running all month. And a flash sale you owe your retention team. Oh, and the regular weekly newsletter.
So you open Klaviyo, look at the calendar, and immediately start stacking sends on top of each other. By the second week, half your audience has gotten four emails about products and three about discounts. Engagement drops. Unsubscribes tick up. The launch underperforms.
Sound familiar? The issue isn't volume. It's that you're treating two very different types of emails like they're the same thing. Understanding the fundamental campaign types is critical before you start planning sends.
Launches and promos play by different rules. Once you separate them in your planning, the calendar gets a lot easier.
They serve different goals
A product launch is a story. You're introducing something new, building anticipation, and giving customers a reason to care. The whole point is that this thing didn't exist last week and now it does.
An ongoing promotion is a discount. The product is the same. The price is what changed. The job is to nudge people who were already considering it to act now.
These are not the same job. A launch email needs to teach. A promo email needs to convert. Mixing them dilutes both.
The classic mistake is using your launch like a promo. "New polo, 15% off this week only." Now you've made a story about a new product feel like every other discount email. And you've trained your list that launches always come with a code, which means next launch they'll wait for the discount instead of buying.
They need different audiences
Launches go wide. Promos go narrow.
For a launch, you want maximum awareness within your engaged audience. Almost everyone who's opened an email in the last 60 days should hear about it. That's the point. New thing exists, here it is, here's why you might care.
For a promo, you want the people most likely to actually buy at that discount level. That's usually your moderately engaged segment, your browse-but-didn't-buy folks, and people who've shown intent on the specific category. Sending a 20% off code to your VIP segment, who would have bought at full price anyway, is just margin you handed back.
The temptation is to send everything to everyone. It feels safer. But broad sends erode targeting muscle over time. You stop trusting your segments because you never use them.
They need different cadences
A launch needs a sequence. Three to five emails minimum, spread over seven to ten days. Teaser, announcement, story behind it, customer reaction, last call. Each one builds on the last.
A promo doesn't need a sequence. It needs a beginning and an end. Launch email, mid-promo reminder, last-day push. That's it. Three sends max, usually two is fine.
When you treat a promo like a launch and write five emails about it, two things happen. People stop opening because they get the message after email two. And your list gets fatigued faster, which makes the next real launch land softer.
When you treat a launch like a promo and send one email, you're leaving the whole story on the table. The product doesn't get the runway it deserves and you're back to begging for revenue with discounts a month later.
They need different metrics
A launch is measured on attach to story. How many people opened more than one email in the sequence. How many clicked through and browsed. How many bought at full price. New customer rate. Average order value.
Open rate on email three of a launch tells you whether the story is working. Click rate tells you whether the offer is clear. Revenue tells you whether you got the audience right.
A promo is measured on conversion velocity. Time to first sale after send. Total revenue divided by sends. Unsubscribe rate. Did the discount move enough volume to justify the margin hit?
These are different dashboards. If you're looking at the same numbers for both, you're missing what each one is actually telling you.
How to actually plan both at once
Here's the part that breaks for most brands. You're not running launches OR promos in a vacuum. You're running both, plus your regular newsletter, plus flows that are already firing in the background.
The planning question isn't "what should we send this week." It's "what story are we telling this week, and what gets in the way of telling it."
Try this. Before you plan any individual emails, lay out the month at the level of themes. This is exactly the approach behind planning 90 days ahead—theme-level thinking prevents week-by-week chaos.
- Week 1: Launch week for new polo. Story-driven sequence. No discounts.
- Week 2: Refresh the audience with a curated bestsellers email. Soft sell.
- Week 3: Sitewide 15% off promo for three days. Targeted to moderately engaged + recent browsers.
- Week 4: Editorial newsletter, no offer. Build trust back up before next launch cycle.
Now each individual send has a job. You're not deciding email-by-email whether to discount or not. The month already answered that.
The other thing this does is force you to space out the heavy moments. If a launch and a promo are crashing into each other in week 2, you can see it now and move one. If you don't plan at this level, you find out by watching unsubscribes climb.
Where Klaviyo's calendar falls short
Klaviyo's campaign calendar is fine for seeing what's scheduled. It's terrible for planning at the theme level.
You can't tag a week as "launch week." You can't see at a glance which sends are story versus offer. You can't visualize which segments are getting hit how many times across overlapping campaigns. So most teams just stack sends and hope. This is exactly why a visual calendar changes how you plan—you need to see themes, not just individual sends.
This is where having a layer above Klaviyo helps. Cadento was built around exactly this problem. You plan at the theme level, see how launches and promos overlap, check audience overlap before you send, and push the actual emails to Klaviyo when the plan is solid. The campaign calendar in Klaviyo becomes execution, not planning.
But you don't need any tool to start. A whiteboard with the next four weeks and one theme per week beats clicking around in the Klaviyo UI hoping the plan comes together.
The takeaway
Launches and promos are different jobs. Different goals, different audiences, different cadences, different metrics.
Stop planning them in the same calendar view. Map the month at the theme level first. Decide which weeks belong to story and which belong to offer. Then write the individual emails.
Your launches will land harder. Your promos will convert better. And your list will stop wondering why you sound confused.
