Best Way to Sync Bulk Uploads of Electrical & Home Appliances?

Question

Hey Klaviyo Experts,I’m Mark Pousee, managing marketing for Power House Express (an online store specializing in electrical accessories, smart home solutions, kitchen appliances, and more). We're looking to ramp up our email campaign strategy, especially ahead of our upcoming sales.Right now, we use CSV imports to add new subscribers, but it’s becoming a pain—lots of data cleaning, inconsistent tags, and frequent duplicates. We're also planning to introduce product-specific sign-ups (like "kitchen deals" or "smart home alerts").Here’s what I’ve tried so far:Uploaded CSV files for different product categories using Klaviyo signup forms.	Tagged new subscribers manually based on their interests (e.g., "Air Purifier Updates").	Tested Klaviyo’s segmentation for “interested in discounts”, but it's not granular enough.I'm wondering:Is there a smoother way via integration—maybe via Shopify or Zapier—that prevents duplicates and automates tagging by product category?	Should we explore Klaviyo’s API for real-time signups from the site?	Anyone else managing a diversified product catalog like ours—what’s your go-to method for keeping email lists tidy and targeted?Would love to hear any workflow examples, integration tips, or Zapier recipes that have worked well for others.Thanks a ton in advance!Mark Pousee

Hey ​@mark.pousee,Welcome to the community! There’s definitely a quicker way to accomplish your goals here - looks like you’re putting a lot of work into your store and segmenting your subscribers, but we can make things a bit easier!What platform do you use to run your online store? Shopify, Magento, BigCommerce, something else? We have integrations with most major Ecommerce platforms, and if you use one of those, I’d strongly recommend using one of our pre-built integrations to integrate with Klaviyo. This will allow you to automatically sync your product catalog over to Klaviyo, along with tracking purchasers, people who view products/add to cart, add sign-up forms to your store, and much more. If you’re on a custom setup, then you can still integrate with Klaviyo via API - it’ll take more work, and the help of a developer, if you’re not a developer yourself, but we have some great resources on how to accomplish this:This article in our developer portal explains the basics on how to integrate with Klaviyo without a pre-built integration.The whole dev portal is a great resource in general, and has lots of articles you can explore regarding sending data to and from Klaviyo.Connect.Klaviyo.comis where you can link up with hundreds of our partners, who can work with you to help set up a custom integrationOur API Reference contains details on all the API endpoints you need to set up a custom integration.Regarding your issue with uploading profiles who are interested in certain products - from what you described, I’m thinking that the easiest fix to this granular process would be to integrate your site with Klaviyo and add sign up forms to your product pages where people can fill them out to show interest in products. You can edit your forms’ targeting settings, so certain forms can only show on certain pages, or pages with certain words in their URL. From there, you can edit the form so submitting it adds a unique custom property to a person’s profile. You’d want each form to add a different property to profiles (Not just a different property value), so the property doesn’t get overwritten when somebody submits another form. Have each form submit to its own list, so profiles enter the list corresponding to the product they want.Let me know if this solution would make sense, or if I missed anything! Happy to help brainstorm a bit more if needed.
