📉 Why Sending More Emails Can Hurt Your Brand
Sending more emails seems like the obvious move when you’re trying to push sales—but here’s the hard truth: more isn’t always better.
Email frequency is a balancing act. If you bombard your subscribers’ inboxes too often, especially with irrelevant content, they’ll do the one thing you really want to avoid: unsubscribe.
And once they’re gone, you lose the chance to reach them again. That’s future revenue off the table.
Common problems caused by over-emailing:
-
Higher unsubscribe rates
-
More spam complaints
-
Decreased open and click-through rates
-
Damaged sender reputation
-
Lower deliverability over time
You’re not just annoying people—you’re burning your list.
❌ How Over-Emailing Damages Your Engagement and Sales
Imagine being nudged by the same store every other day with emails saying “Buy now” or “Last chance”. It might work the first time. Maybe even the second. But by the fifth or sixth email in a week, your audience tunes out or marks you as spam.
What happens next?
-
Your emails land in Promotions or Spam folders
-
Your open rate drops
-
Your revenue per recipient plummets
If you’re running Klaviyo, you can track this inside your campaign performance dashboard. Look for declining trends in open and click rates—classic signs you’re over-sending.

📊 Ask Your Audience How Often They Want Emails
One of the easiest ways to fix over-sending? Just ask.
Set up a quick survey (use Google Forms, Typeform, or even a Klaviyo form) and ask your subscribers:
“How often would you like to hear from us?”
Offer them frequency options like:
-
Once a week
-
Twice a month
-
Only for sales/promotions
-
Once a month
📌 Bonus: Build segments based on their preferences using Klaviyo’s custom properties.
You’ll reduce unsubscribes and increase engagement—because now you’re meeting people where they are.
🧠 Personalisation vs Hyper-Segmentation: Find the Balance
Yes, personalisation works. Addressing people by name, mentioning past purchases, or sending product recommendations boosts conversion. But when you go too far down the hyper-segmentation rabbit hole, things break.
For most ecommerce brands, segmenting by gender, purchase behaviour, or engagement level is more than enough.
Why hyper-segmentation can backfire:
-
You limit your reach per campaign
-
Content creation becomes more complex and time-consuming
-
Your testing pool shrinks—making A/B tests statistically weak
-
You lose the chance to promote bestsellers across your full audience
👥 Simpler is smarter. Start broad, then refine based on results.
🔁 Better Strategies Than Just Sending More Emails
Instead of flooding inboxes, try:
1. Lifecycle Flows
Set up essential flows like:
-
Welcome series
-
Abandoned cart
-
Browse abandonment
-
Winback campaigns
These are triggered by behaviour, not bulk timing. So they hit when people actually care.
2. Segment by Engagement
Use Klaviyo’s “Engaged in last 30/60/90 days” metric. Only email active users during peak campaigns like BFCM. Suppress the rest.
3. Use Smart Send Times
Let Klaviyo or your ESP calculate optimal send times based on recipient behaviour. Better timing = higher open rates.
4. Test Before Scaling
A/B test subject lines, content, and frequency. Don’t just assume more emails = more sales.
