Application Mail Relay Service — Reliable Email Delivery for Business Software

Outbound mail relay for applications and systems — included in every managed service

Applications that send email — order confirmations, notifications, system alerts, backup reports — need a reliable outbound path. Sending directly from a server is unreliable: IP reputation, SPF records and blacklisting all affect deliverability. A properly configured mail relay ensures your application's email actually reaches recipients.

Cloud365 provides managed mail relay as part of every managed service — your hosted application sends through our relay infrastructure, which is properly configured with SPF, DKIM, DMARC authentication, IP reputation management and delivery monitoring. If your application's email isn't reaching recipients, we investigate it.
