Everything you need to secure your outbound email communications and build recipient trust
Mail clients, applications, ticketing systems, and invoicing platforms submit outbound email using authenticated SMTP on port 587 with STARTTLS encryption.
Each customer has isolated configuration, sender domain rules, and rate limits to prevent cross-tenant spoofing and abuse.
Every outbound email includes a unique “Verify this message” link, allowing recipients to confirm legitimacy instantly.
Recipients click the link to view a verification page showing sender, recipient, subject, timestamp, and verification status.
Supports modern MIME email structures, preserving PDFs, invoices, screenshots, and inline logos for real-world MSP communications.
Verification events and sending metadata are logged for compliance, investigation, and customer assurance.
No IP-allowlisting required. Supports customer environments where IP-based connectors are not permitted using modern authentication methods.
Compatible with Microsoft 365, Google Workspace, and on-premises Exchange/SMTP servers without migration.
Simple, secure, and seamless integration with your existing email infrastructure
Customer mail clients or systems submit email to the Xaccel Gateway using authenticated SMTP (587 + STARTTLS).
The gateway injects a unique verification code and verification link into the email automatically.
The message is relayed outbound through the customer’s existing email platform (Microsoft 365, Google Workspace, or on-prem SMTP).
The recipient can click the verification link to confirm authenticity on the Xaccel verification portal. Records expire automatically and lookups are logged.
