How the Integration Works
Once your accounts are linked, MailBoost acts as the ultimate safety net for your checkout process:
Visitor triggers on-site event on the shop → The MailBoost pixel instantly captures it.
MailBoost identifies the user → We recognize the customer, even if they have slipped off Klaviyo's radar.
Data syncs to Klaviyo → The triggered event is pushed to Klaviyo, enriched with the referenced email by MailBoost.
Klaviyo Flow gets triggered → Customer receives email based on your flow.
How to Activate MailBoost
In MailBoost, we made the integration and activation as easy as possible.
Step 1: Navigate to Connections
Navigate to the Connections tab in the left-hand menu (or click here).
Click on the button "Connect with Klaviyo".
Step 2: Grant Klaviyo Authorization
From there you will be securely routed to Klaviyo's authorization page.
Click Allow to give MailBoost the permissions it needs to sync your events.
Step 3: Boost Your Flows
After authorizing the connection, navigate to the Flows tab in the left-hand menu (or click here).
Browse the list of your active Klaviyo flows.
Boost a flow by clicking on the "Boost" button.
From there MailBoost will automatically handle the heavy lifting:
Cloning the selected flows.
Inject the required MailBoost event triggers.
Configure smart timing delays so customers never receive duplicate messages.
Important Note: Due to Klaviyo's API limitations, flows containing active A/B tests cannot be cloned automatically. You will need to set these up manually.
Step 4: Transfer Re-Entry Criteria
Take a quick look at your newly duplicated MailBoost flows in Klaviyo. If your original flows relied on specific re-entry criteria (rules dictating how often someone can enter a flow), you will need to manually copy those settings over to your new MailBoost flows to keep your marketing logic intact.
Common Question: Should I pause the original flows?
No. MailBoost flows will only be sent, if the original flow wasn't triggered.
