A splendid campaign is wasted in the spam folder. Validity has spent its acquisition budget assembling the less glamorous machinery that gets customer data clean and email seen.

The French sales platform has spent eight years turning a personalization trick into an outbound control room. Here is who should use it, what the credits really buy, and where the charm meets the spreadsheet.

Maverick is a San Francisco AI startup that generates personalized videos at scale for ecommerce brands. A merchant records one short base video, and Maverick's generative AI clones the voice and reshapes it to greet each customer by name across email flows - welcome, post-purchase, abandoned cart and more. The platform layers on inbox-placement optimization and automatic subject-line A/B testing, and plugs natively into Klaviyo. Founded in 2021 by Eitan Winer and Debarshi Chaudhuri, Maverick sells the idea that online shopping should feel a little more like being recognized by name at your neighborhood store.
