Email Suite

Because deliverability is a product, not a setting — and at the volumes the ZUI universe sends (millions a month), outsourced reputation is a single point of failure. Email Suite gives ZUI customers the same engine we use ourselves: tuned, monitored and improved every week.

ZUI Technology S.L., a Spanish technology holding of engineers, designers and operators. Every product in the ZUI universe runs in production with real customers and real revenue on the line — we don't ship demos, we ship systems we operate ourselves. Email Suite started as ZUI's internal infrastructure and was opened to selected customers once it proved itself in production.

Direct access to the team that built the product — not an outsourced call center. Each customer joins a shared channel with the product team. Custom SLA tiers negotiated by volume; named engineers accountable, not ticket queues.

ZUI doesn't sell hours — it sells systems that keep performing year after year. The relationship starts with one product and grows: clients add more pieces of the ZUI universe (CRM, automation, email, infra) as they scale, with one accountable partner across the whole stack.

Yes. EU-resident infrastructure, native consent receipts, suppression lists shared across the customer's full ZUI footprint, and a legal posture that treats GDPR as a baseline, not a feature.
