Klaviyo development services
Whether you are new to Klaviyo or want more from the account you already have, our developers cover the full setup.
Setup and migration
A clean Klaviyo account from day one, or a move from Mailchimp or another platform with your lists, consent and history intact.
Flows and automations
Welcome, browse and cart abandonment, post-purchase, replenishment and win-back flows that run on their own.
Email templates
Branded, mobile-friendly templates your team can reuse, including coded templates when the drag-and-drop editor is not enough.
Sign-up forms and SMS
Pop-ups, embedded forms and SMS programs that grow your list while staying within consent rules.
Integrations
Klaviyo connected to Shopify, BigCommerce, SuiteCommerce, NetSuite, reviews, loyalty and support tools.
Segmentation and reporting
Segments built on purchase behavior and predicted value, and reporting that shows which flows and campaigns earn the most.
Technical depth where it matters
APIs and custom events
Custom events and profile properties sent through Klaviyo’s API, so flows can trigger on anything your business tracks.
Product catalogs
Catalog feeds that keep product recommendations, prices and stock levels in your emails accurate.
NetSuite data
Orders, customers and items from NetSuite, including phone, wholesale and in-store orders that never touch the storefront.
Deliverability
Domain authentication, list hygiene and sending practices that keep your emails out of the spam folder.
Why brands choose SCG’s Klaviyo developers
We build the stores too
SCG builds Shopify Plus, BigCommerce and SuiteCommerce stores, so we know where the data comes from and how to get it into Klaviyo cleanly.
Commerce and ERP together
Most email agencies only see the storefront. We also implement NetSuite, so your flows can use every order and customer, wherever they came from.
One accountable team
Strategy, development, design and support come from the same team, with clear timelines and regular reporting.

Frequently asked questions
What does a Klaviyo developer do?
A Klaviyo developer sets up and connects your account, builds flows, templates and sign-up forms, sends custom data through the API, and makes sure your segments and reports use accurate store data.
Can you move us to Klaviyo from another email platform?
Yes. We move your lists, consent status, templates and key automations from Mailchimp or another platform, and rebuild flows so they take advantage of Klaviyo’s ecommerce data.
Can you connect Klaviyo to NetSuite?
Yes. We connect NetSuite through Klaviyo’s API or a proven connector, so orders, customers and products from every channel are available in Klaviyo. See our Shopify NetSuite integration service for how we connect the store and ERP.
Which ecommerce platforms do you connect to Klaviyo?
We work with Shopify and Shopify Plus, BigCommerce and SuiteCommerce, along with the reviews, loyalty, subscription and support tools that run alongside them.
Do you build SMS programs in Klaviyo?
Yes. We set up SMS sign-up, consent, flows and campaigns, and coordinate them with email so customers are not over-messaged.
Can you fix flows that are not performing?
Yes. We review your flows, segments and deliverability, find where customers drop off, and rebuild or test the parts that are underperforming.
