MailSync integration: NetSuite with Outlook Mail
Unlock the full potential of your business communications with our seamless MailSync and NetSuite integration.
This backend integration ensures every email is automatically captured and synced into NetSuite according to custom rules and logic—providing a consistent, reliable system of record without relying on manual entry.

What is a MailSync - NetSuite integration?
A MailSync–NetSuite integration connects email inboxes directly with NetSuite, automatically logging communications without requiring user action.
SuperSync MailSync runs in the background, applying predefined rules to determine how emails from each enrolled address should be treated. Messages can be routed to the correct customer, contact, opportunity, or case in NetSuite—ensuring accuracy, consistency, and real-time visibility across your organization.
