How are my contact databases matched to establish the sync?
- To establish a sync, we match contacts between two apps based on the email address field:
The sync or 'binding' we establish between two apps during the initial sync, will stay in place once the sync is active, regardless of the changes you make to the contact after, even on the email address level.
- What to do when you have contacts without an email address?
Have a look here to see how you best move forward, in particular with our Avoid Duplicates feature.
- In the Default Field Mapping, you can see how the email address field is mapped.
