Our Story


What Makes Transend Unique!

When selecting Transend to support your migration needs, you’re getting more than just a piece of software. Transend offers different engagement models that meet different customer needs. If you lack technical expertise or don’t have the time or resources to perform the project internally, you can simply offload all migration-related processes and efforts to Transend and let our services engineers do the heavy lifting for you. Or, you can migrate your email data yourself with Transend software and the support package that comes with it.

Transend offers multiple offerings focused on industry needs:

Software Offering:

With technology specifically designed for rapid throughput, maintenance of data fidelity, adaptability, scalability and ease-of-use, Transend’s software solutions are used by enterprise organizations migrating thousands of mailboxes, small to medium businesses, and individuals converting their personal mailbox.

Transend Migrator — Migrates email email data from one email system or file type to another (i.e.: G Suite > Office 365, Domino > Exchange, .nsf > .pst, etc).

Transend Migrator Forensic Edition — Converts email data to formats suitable for eDiscovery or compliance needs, rather than into a live email server/platform.

Services Offering:

Regardless of your specific needs, Transend engineers can perform all email migration related services from beginning-to-end. From Assessment, Discovery & Architecture of a project plan, to Implementation & Deployment of infrastructure, to performing Benchmark & Validation Testing, Pilot and the Production migration processing…Transend can architect and execute the entire project with its own US-based migration experts. When leaning on Transend to perform your migration, you’re relying on a team of professionals who have performed thousands of migrations and have experienced all associated issues, hurdles and pain points that must be overcome to ensure a successful migration.

A unique aspect of Transend’s professional services offering is that we’re not only the migration service provider, but also the software developer! All services will be performed by Transend personnel – US based migration experts who understand the necessary nuances and architecture of our software better than anyone. Unlike most consultants who rely on 3rd party software, we don’t need to rely on anyone else’s email migration technology, experience or technical support. When an issue does arise, we won’t be sending support tickets to an international queue resulting in unnecessary delays or IT purgatory. Our engineers simply pick up the phone or walk into an office to communicate with our senior developers to ensure troubleshooting is performed at the highest level, yielding hot fixes that are prepared real-time. This direct line of communication between Transend’s engineers, project managers and senior development team represents an efficiency that is truly unique and positions migration projects for unparalleled success.

Transend’s History

Transend Corporation has a long heritage in the email market dated back to the birth of email. Transend invented the concept of specialized PC-based email clients in 1983 with a product called PC COMplete™, the first “universal” email client — a concept now incorporated in Microsoft Outlook. Private label versions of PC COMplete were marketed by GE Information Services, AT&T, Pacific Bell, HP, CSC Infonet, BT Tymnet, DEC, BIMCOM Ltd., Teleo S.p.A. and others. In 1993, PC COMplete was nominated by EMMS, a leading email industry publication at the time, for Product of the Decade because of its contribution to the growth of email.

In the early 1990’s Transend began working directly with Microsoft to develop a MAPI-based driver for DEC MAILworks. This project led Transend and Microsoft to work together to develop an email driver for Lotus cc:Mail that would plug into the precursor of Microsoft Outlook. When Microsoft Outlook was released, the Transend cc:Mail driver was bundled and distributed by Microsoft in Microsoft Office and Outlook. Transend later released a portion of that technology as a stand-alone email conversion utility, ConnectorWare Import for cc:Mail, for importing cc:Mail messages and address books into Microsoft Outlook/Exchange.

Transend has unparalleled experience in the development and commercialization of solutions for messaging systems providers worldwide. Perhaps the best indication of Transend’s qualifications is the breadth and quality of its customers. In addition to its current email migration and conversion solutions, Transend has developed custom email software solutions under direct contracts with Microsoft, Digital Equipment, IBM, Apple, Hewlett-Packard, AT&T, Pacific Bell, British Telecom, Kokusai Electric, SARITEL S.p.A, Hong Kong Telecom, Infonet and others. Transend’s extensive experience with email conversion technology and a wide variety of email systems and clients, led to its current industry leading, award winning, email migration and conversion solutions.

Transend has current partnerships with Microsoft, IBM, Amazon, Micro Focus, Google, Barracuda and other leading edge collaboration providers.
