Eine flexible Integration für alle Fälle

Server-side integration


Every email sent by your employees - regardless of which device - is routed to your Exchange Online (1). From your Exchange Online, the email is routed to one of our european Azure servers, which is also hosted within the Microsoft Office 365 Data Center. At this point (2), the appropriate employee's signature is added before the email is delivered to the recipient as usual via your own Exchange Online (3).

Client-side integration

Rerouting Mailtastic Office 365

Our desktop application EasySync is installed on the workstations. This can easily be done centrally for all employees via GPO. EasySync ensures that your employees always have the latest Mailtastic signature available (1). The employee always sees the most current signature when writing the mail in Outlook and can choose between several signatures if desired (2) before sending the email with the desired signature to the recipient (3).

Combined Integration

Rerouting Mailtastic Office 365

You can easily combine server-side and client-side integration to combine the advantages of both methods. Through our desktop application EasySync, the employee can choose between different email signatures and see the signature when writing the email (1). After sending - regardless of which device - the email is forwarded to your Exchange Online (2). From your Exchange Online, the email is routed to one of our european Azure servers, which is also hosted within the Microsoft Office 365 Data Center. At this point (3), the appropriate signature will be added, if not already available, before the email is delivered to the recipient as usual via your own Exchange Online (4).
