The problem it solves

SMTP relays are increasingly restricted by Microsoft 365 tenants. Modern integrations need OAuth, MFA-compatible auth, and the Graph API — not username/password SMTP.

Target market

Organizations on Microsoft 365 needing automated mail (transactional notifications, helpdesk ingestion, document delivery) from line-of-business systems.

Key modules & features

  • Module 01

    OAuth via Microsoft Identity

    Application and delegated permissions — no plaintext mailbox credentials.

  • Module 02

    Send with Attachments

    Multi-recipient send with file and inline attachments.

  • Module 03

    Inbox Processing

    Read, classify, and act on incoming mail for helpdesk and automation flows.

  • Module 04

    Tenant-Scoped Configuration

    Per-tenant client IDs, secrets, and target mailboxes.

Benefits

  • Stay aligned with Microsoft's deprecation of basic-auth SMTP
  • Audit-friendly via Microsoft 365 admin logs
  • Foundation for helpdesk and document workflow automation
