There is not an email notification but you can do two things to check the bulk mapping status:
- Go to Sync Products to check the sync status of the products. A 'Synced' status means that it has successfully mapped.
- Check for mapping failures through the activities log.
Syncio will identify which products couldn't be mapped due to duplicate SKUs, mismatch of SKUs and/or variants.
The log can be found in your destination store to the top right side - its an icon that looks like a bell.
