How do Klaviyo integrations benefit merchants?

• Triggering email and SMS flows and personalizing content with purchase data, shipping data, support tickets, and more.
• Adding custom profile properties, such as loyalty program points or tiers, for better segmentation.
• Creating email templates and images.
• Orchestrating message sending through campaigns.
• Pulling analytical data from Klaviyo to display customer engagement with a brand.

We are dedicated to our developer community and offer a range of resources, including:

• A dedicated Developer Group in the Klaviyo Community for connecting with Klaviyo developers (there are over 1200), receiving troubleshooting support, and accessing inspiring use cases.

FAQ

How do I chat with someone on the partnership team and get support?

As much as we’d like to, we are unable to work directly with every platform that integrates with Klaviyo, so we do not offer a way to contact the partnership team directly. That being said, our team is committed to adding value for partners by making integration more accessible, expanding our developer ecosystem, and building a more engaging partner program.
