Klaviyo's multiproduct capture and retention
Klaviyo: the $665M/year HubSpot for ecommerce
Klaviyo’s multiproduct push is really about turning one successful email tool into the system a merchant runs more of its customer lifecycle through. If a brand already stores shopper profiles in Klaviyo, sends email there, then adds SMS, chat, and CDP style data syncing, each new workflow raises spend without forcing a new vendor search, and it gets harder to rip out Klaviyo because more campaigns, data flows, and teams depend on the same customer record.

The adjacent revenue piece is concrete. Klaviyo expanded from email into SMS, which had already reached about 10% of revenue in the period covered here, and then into enterprise CDP and in app messaging. That lets it sell more products to the same merchant instead of waiting for email volume alone to grow.
-
The retention piece comes from owning the data model. Klaviyo’s early strength was giving merchants a live customer profile they could segment without spreadsheets. Once order history, subscription status, app events, and support or messaging triggers all sit in one system, replacing that system means rebuilding the logic behind campaigns, segments, and automations, not just swapping an inbox tool.

This was also a defensive move against Segment and channel specialists. Segment lowered switching costs by acting as a neutral router for customer data, and Twilio bought it for about $3.2B. At the same time, specialists like Attentive and Postscript pulled SMS budget away from email platforms. Building more products around the customer profile let Klaviyo recapture both data control and wallet share.
The next step is broader workflow capture around the merchant’s customer record. The more Klaviyo can make email, SMS, service, and shopper data feel like one operating surface, the more it starts to look less like a campaign app and more like the default operating system for ecommerce brands, which is where the biggest expansion and retention gains sit.
