UniOne

UniOne runs high-deliverability transactional and bulk email through a REST API and SMTP with a documented 99.88% delivery rate and send times measured in seconds. Product, growth, and engineering teams use UniOne for receipts, password resets, notifications, and newsletter sends without the per-email markup of US-based providers.

The platform pairs a drag-and-drop template builder and AI-powered HTML editor with webhook event notifications, visual dashboards, and 100-day CSV-exportable logs. Dedicated IPs, branded tracking domains, and a built-in email validation API protect sender reputation, while a four-layer security architecture encrypts data in transit and at rest.

Key benefits:

• REST API and SMTP covers transactional and bulk sending
• 99.88% delivery rate with several-second send times
• Drag-and-drop and AI editor builds 40+ ready-made templates fast
• Webhooks and dashboards stream delivery events into your stack
• Email validation API cleans lists and protects sender reputation
• White-label tracking domains keep links and clicks on your brand
