About Zembula

Zembula adds verifiable incremental revenue to baseline email performance through measurable image personalization.
For performance marketers, email has been a black box: campaign-level revenue, no creative-level attribution, no incremental lift testing.
Zembula gives email the measurement fidelity the rest of the performance stack already has: block-level attribution, longitudinal holdout testing, and personalization that's provable at the asset level.
For the email and CRM teams who run the channel, that means designing once and personalizing endlessly: on-brand, at scale, without additional creative work or html updates. One image url. Any content. Any moment. Measured.
Trusted by leading retail brands like j.crew, madewell, spanx, and nobull, zembula turns email from a black box into a measurable performance channel.
