MNTN (NYSE: MNTN) and Klaviyo (NYSE: KVYO) have announced a two-way integration that connects MNTN's Performance TV platform with Klaviyo's email and SMS marketing tools, according to a press release from the companies.

The integration allows marketers to use Klaviyo audience segments — including repeat buyers, cart abandoners, and lapsed customers — to target Connected TV advertising on MNTN. After a viewer is exposed to a TV ad, the integration can automatically trigger personalized email and SMS flows within Klaviyo.

Audience data syncs daily between the two platforms, removing the need for manual exports. The integration is available to advertisers who hold an active Klaviyo account with at least one audience list or segment.

"TV has always been great at starting conversations. It just wasn't invited to the follow-up," said Mark Douglas, CEO of MNTN. "Integrations like this unlock the credibility and scale that TV can deliver for brands of any size."

"Marketing automation shouldn't stop short of TV," said Eddie O'Brien, SVP of Global Partnerships and Alliances at Klaviyo. "By bringing Performance TV into those same workflows, marketers can reach their most valuable audiences on the biggest screen in the home and continue the conversation across all of the biggest channels."

The companies noted an existing overlap in their customer bases, particularly among retail and e-commerce brands. Klaviyo is described as one of MNTN's largest technology partners.
