The Implementation Consultant will assist you in the following taks. The Implementation Consultant will set up:

1. Channel-specific fields in the contact database (e.g. sinch_engage_wb, sinch_engage_wb_opt_in and other custom fields),
2. Contact import and update processes to populate Channel-specific identifier fields in Emarsys, 
3. Channel-specific contact acquisition journeys,
4. Contact database cleanup processes.

Once the Implementation Consultant has confirmed completion of this task, the Contact Synchronization feature is activated in the add-on (it is grayed out to prevent accidental import of contacts without a matching identifier available).
