Zembula internal data shows that switching from SparkPost resulted in a 37% lower latency switching from SparkPost before full warm-up.

Most personalization solutions can't tell you what it earned. That's the problem we exist to fix. Zembula is built on one conviction: images in email are the most valuable real estate a brand owns in its email program, and it should be personalized, on-brand, and accountable. We built one intelligent layer that sits above your customer data layer. Any image in email, infinitely personalized. The difference is proof. Every image is measured on email last-click against real transactions, so you see the exact revenue each image block and block-variant drove. Once performance is proven in your email program, centralize personalization orchestration: use the same Zembula image tags across other surfaces, including web, mobile, push and RCS. Personalization stops being a story you tell and becomes a number you can stand behind. One image tag, infinite personalization, measurable creativity.
