Transactional email sending domain

A sending domain.
Nothing more.

sentemail.co is a private domain used to send transactional and operational email on behalf of a small portfolio of internal projects — authenticated end‑to‑end and routed through reputable infrastructure providers.

About the domain

What is sentemail.co?

sentemail.co is a private sending domain. It exists to deliver transactional and operational email — receipts, confirmations, password resets, account notifications, and product updates — on behalf of a small portfolio of internal projects.

It is not a service for sale. Every message includes a no-reply-to address on a non-monitored inbox, every marketing message includes a one-click unsubscribe, and abuse reports are reviewed.

Authentication

Authenticated end‑to‑end.

Mail from sentemail.co is signed and verifiable. The three pillars of modern email authentication are all in place and continuously monitored.

TLS is required for transport. Sending IPs are warmed and segregated by traffic type. Suppression lists and bounce handling are honoured across every provider.

Infrastructure

Routed through trusted providers.

Outbound mail flows through established email infrastructure providers — chosen per project for the workload. Each is authenticated against the sentemail.co domain.
