Yes, you are able to view guest emails if you only have guest IDs but only in an indirect way as there is no specific function within Punchh to allow this.
- Head to Guests > Segments
- Create a new Custom List Segment
- Paste the guest IDs in the list
- Select Save and Show
- Select Edit
- The list will now have been converted to guest emails
NOTE: This method will have a cap of 2,000 guest IDs that can be entered. If there are more than 2,000, then you would need to create more than one. Please see Can I create a Segment with only guest IDs? if you do not need the guest email.
