SeatLessMail — Email infrastructure for your application
Email infrastructure you own

Run your email in-house — not on someone else's subscription.

SeatLessMail is a streamlined email platform for managing contacts, sending broadcasts, and automating lifecycle messages — built to live inside your own application and infrastructure.

This service is available to clients of SeatLess Software and is not available for direct sign-up.

Everything you need to send email well

The tools to run a reliable, compliant email operation — without paying per-seat SaaS fees.

Contacts & audiences

Manage contacts, segments, and subscription preferences in one place, with consent and unsubscribe handling built in.

Broadcasts

Compose and send broadcast emails to your audiences using a visual editor, with reliable cross-client rendering.

Automated sequences

Build onboarding and lifecycle emails that send based on a contact's activity — no manual triggering required.

Reporting & deliverability

Track delivery, opens, clicks, bounces, and complaints. Authentication (SPF, DKIM, DMARC) and suppression are handled for you.

Who it's for

For teams that want to own their email stack and avoid escalating per-seat SaaS fees — a custom email capability embedded in their own product, not another platform subscription. SeatLessMail is provisioned for clients of SeatLess Software; it is not available for independent sign-up or self-service access.
