  4. Finally, the connection must be configured. You select in which direction the synchronization should be carried out and how often this should happen.


  • Multi-Way Sync:

Connections can sync one-way or both-ways between two apps.

  • Avoiding duplicates:

Before each synchronization process, the contacts of the applications are examined to determine, based on e-mail addresses and names, whether newly created contacts already exist in the other application, thus avoiding duplicates.

  • Synchronization intervals:

When configuring a connection, you can select the interval at which synchronization should be carried out. You can select manual, hourly, daily, weekly or monthly.

  • Simultaneous synchronization:

You can create any number of connections in your account and choose from all available apps at no extra charge.
