Transactional email service

I recently integrated a new transactional email service https://unione.io/en/transactional-email-service into our platform, and it’s truly strengthened our user experience. What impressed me most was how reliably messages like password resets, OTPs, and confirmations are delivered — rarely a bounce or delay in sight. The API documentation is clean and developer-friendly, making setup seamless even for non-engineers.

Monitoring tools give real-time visibility into delivery rates, bounce alerts, and spam filtering issues — an absolute must when your emails affect user trust and security. The interface also allows fine-grained control over sender addresses, domains, and templates. Whether I’m sending account notifications or billing statements, the formatting stays consistent and on-brand.

Overall, customer support was responsive whenever I had questions about DKIM setup or IP warm-up. This transactional email service has become an essential backbone for our operations — reliable, scalable, and easy to maintain over time.
