Ensure carrier-grade email with a private SMTP relay

Transactional emails need to reach the recipient straight away. Long waiting times for alerts, password recoveries, authentication codes, or appointment confirmations negatively impact your user’s experience.

At Alinto, we designed a private smtp relay with transactional and marketing messages in mind. Focusing on reliability, it guarantees your transactional emails will reach their destination promptly and every time. Delivering a more personalised customer experience with a transactional emails service is now easier than ever. And Alinto does all the hard work to ensure the emails are delivered on time.
