What's something you'd tell someone who wants to get more out of Klaviyo integrations and APIs?

Something great happened with my freelancing business that I wanted to share.

About a year ago, I helped a client in the T-shirt printing business integrate their ecommerce store with Klaviyo. The catch: their store is built on Deco, which isn't a supported Klaviyo integration.

The solution had two parts: injecting custom JS on the storefront, plus a server-side piece built in Make.com that calls Deco's APIs to retrieve orders and pushes them into Klaviyo as custom events.

After finishing the project, I wrote it up as a case study on my website. I didn't think much of it at the time.

Fast forward a year, and I just got an inquiry purely through organic search from someone in the exact same situation: running Deco and trying to connect it to Klaviyo. They found my case study, realized I'd already solved their problem, and reached out.

The lesson for me: document your niche work publicly. The more specific the problem you solve, the more likely the right person finds you when they search for that exact thing later.

One of the biggest time savers in my workflow has been Cadence Campaigns. It automates campaign scheduling and configures a webfeed for content publishing, so I update a Google Sheet and the content flows straight into a pre-formatted Klaviyo template on schedule.

For agencies managing multiple accounts: once it's set up, I'm not logging into Klaviyo to build and schedule each campaign. I'm just filling in a spreadsheet.

For individual accounts: it removes the repetitive campaign setup work.

Flexibility: content updates are just spreadsheet edits, no need to open the template editor.

Safety: content populates into a template you've already built, optimized, and tested, so there's no risk of breaking. Easy to delegate to a team member without giving them full Klaviyo access.

Time saved: I use AI to preformat campaign content directly into the spreadsheet, which cuts down the time to fill the spreadsheet. 

Better optimization: Klaviyo's campaign analytics don’t see what's actually in the body of the email. Pairing that analytics data with the spreadsheet's content history gives AI the full picture, so you get sharper insight into what's actually resonating with your audience.

This system frees up energy to focus on what actually moves the needle: the content itself.

If manual campaign setup is eating your time, worth a look.

My #1 tip: don’t send data into Klaviyo just because it exists. Send the data that creates a clear next action.

The layer that usually makes integrations and APIs more valuable is not “more data,” it’s better-planned data.

Before adding a new event or property, I’d ask:

• What flow could this trigger?
• What segment could this improve?
• What message would this personalize?
• What decision would this help us make?

One example I see a lot is quizzes or recommendation tools. Instead of passing every answer into Klaviyo, send the outcome, recommended product/category, and a few key preference properties. That gives you enough to trigger a personalized follow-up flow, build useful segments, and tailor future campaigns without cluttering the profile.

Same goes for custom events. A well-named event like Completed Quiz, Reached Loyalty Tier, Subscription Skipped, or Booked Appointment can be much more useful than syncing every small interaction.

So my contribution to the list would be: map the customer journey first, then only pass the events and properties that help you act on that journey. Clean, intentional data almost always beats “send everything and sort it out later.”

Hope this helps!
