Omnichannel marketing FAQs
What is omnichannel marketing?
Omnichannel marketing is a strategy that connects all customer touchpoints—such as email, SMS and others—into a seamless, real-time journey. It uses a unified customer profile and AI-driven insights to deliver personalised messages across every active channel.
How is omnichannel different from multichannel marketing?
‘Multi’ means ‘multiple’, so a multichannel marketing strategy uses more than one channel to reach customers—often independently. ‘Omni’ means ‘all’, and in omnichannel marketing, the focus is on integrating all active channels to create a seamless and co-ordinated customer experience across them.
Which marketing channels does Klaviyo Omnichannel support?
Klaviyo supports omnichannel marketing across:
- Email messaging
- Text messaging (SMS, MMS, RCS)
- Mobile push notifications and in-app messaging
- Product reviews
- In-store activity (via POS integrations)
All channels are connected through a single B2C CRM for consistent messaging and improved results.
What is the process for building omnichannel marketing campaigns?
To create a successful Klaviyo omnichannel campaign, start by:
- Building a unified customer profile from data across touchpoints
- Defining customer journeys that span multiple channels
- Using Klaviyo’s automation tools to trigger timely, personalised messages based on real-time behaviours
- Testing and refining based on omnichannel performance metrics
Can I automate omnichannel campaigns?
Yes. With Klaviyo’s marketing automation, you can automatically trigger emails, texts and other messages based on real-time customer activity – such as purchases, site visits and engagement across channels. This ensures timely, relevant communication that adapts as your customers interact.
How do I measure omnichannel marketing performance?
Klaviyo offers cross-channel analytics and attribution, giving you a complete view of how each marketing channel contributes to customer engagement and conversions. Monitor performance across campaigns and flows to see what’s working—and where to optimise for a higher ROI.
