A practical checklist for Shopify store owners using Klaviyo
Checkout bots don’t just create “fake” abandoned checkouts they distort your data and damage your email deliverability.
Why this matters
When checkout bots in Shopify trigger Klaviyo abandoned checkout emails, they can:
- Inflate Checkout Started numbers
- Create emails sent to fake or invalid addresses
- Increase bounce rates in Klaviyo
- Negatively impact your deliverability score
- Make future campaigns more likely to land in spam
- Skew funnel and conversion reporting
This is a data quality and deliverability issue, not just a reporting problem.
Start here: practical steps you can take
If abandoned checkouts are creating higher-than-normal bounces in Klaviyo, here's what you can do.
1) Block bots in Shopify
Example: Blockify (or similar bot-blocking apps)
What this does:
Helps block suspicious traffic before bots move through your store and reach checkout.
Why this matters:
Stopping bots early reduces fake checkout starts, decreases invalid email addresses being synced to Klaviyo, and lowers the risk of bounce-related deliverability damage.
Important note:
Shopify apps don’t run inside checkout itself, so some bots will still slip through. That’s why storefront blocking works best alongside Klaviyo-side filtering.
2) Filter bot profiles inside Klaviyo
Example: Mail Ward (or similar Klaviyo apps)
What this does:
Identifies likely bot or low-quality profiles and keeps them out of key flows such as Abandoned Checkout and Welcome.
Why this matters:
This reduces bounces, protects your sender reputation, and keeps Klaviyo analytics cleaner and more accurate.
Important note:
This doesn’t stop bots from being synced to Klaviyo from Shopify, but it does prevent them from triggering flows that negatively impact your deliverability.
What doesn’t work (and why)
Some store owners try to manage checkout bots by:
- Creating Klaviyo segments to identify and suppress bot profiles
- Adding flow filters to suppress suspected bots
- Using a webhook to automatically suppress bots
Why this falls short:
These steps only act after the damage is already done.
By the time a bot can be identified in Klaviyo with these methods:
- The profile has already been created
- One or more emails may have already been sent
- A bounce may have already occurred
- Your deliverability has already taken a hit
Segments and flow filters can reduce ongoing noise, but they don’t prevent the initial bounce or protect your sending reputation.
That’s why storefront bot blocking and Klaviyo-side filtering work best together. They stop damage before it starts.
How to think about all of this together
- Shopify bot-blocking apps stop bad data at the source
- Klaviyo filtering tools protect deliverability and reporting
Takeaway
Take control of your store data and email deliverability by stopping bot damage before it impacts your sending reputation.
