Avoid These 5 Klaviyo Email Marketing Mistakes

I’ve audited over 100 7-figure ecommerce Klaviyo accounts.

These 5 common mistakes are costing brands money daily. Fixing them often leads to thousands in extra revenue within a month.

Let’s break them down:

Mistake #1: Smart Sending Turned On

Smart sending skips flow emails if someone received another email within 16 hours.

While the idea is good, it hurts conversion opportunities—like skipping a cart abandon email for someone who clicked a campaign earlier.

To fix:

• Go to a Flow email → Settings → Turn Smart Sending OFF.

Mistake #2: No Real Cart Abandon Flow

Many brands confuse the Checkout Abandon Flow (default in Klaviyo) with a Cart Abandon Flow.

The difference? Cart Abandon captures users who added an item to their cart but didn’t proceed to checkout.

If you’re missing this trigger, you’re losing revenue.

• Check for the Abandoned Cart metric under Metrics in Klaviyo.

• If it’s not there, follow this Shopify guide.

Mistake #3: Sending To Your Whole List

Blasting your entire email list = spam folder disaster.

Inactive profiles and dead emails drag your open rates below 35%, hurting your sender reputation.

Instead:

• Create an Engaged List (contacts active in the last 60–90 days).

• Send campaigns only to those who want to hear from you.

Mistake #4: Weak or Missing Pop-Up Forms

Pop-up forms are your email marketing foundation.

Most brands convert just 3–4% of site visitors into subscribers. Our clients? 10%. That’s 3x more list growth = 3x more revenue.

Focus on clear designs, strong offers, and mobile optimization to improve conversions.

Mistake #5: Only Sending Sales Emails

Constantly sending sales emails will bore your audience.

Mix it up with content like:

• Behind-the-scenes

• Fun facts or myth-busting

• Funny reviews

It builds brand loyalty, boosts engagement, and drives long-term sales growth.

Fix these mistakes, and you’ll stop leaving money on the table.
