We are investigating an issue with regards to group aliases failing for StreetData when customers send Email to SMS. This affects all Email to SMS directed in the format of: @streetdata.com.au. This affects group sending functions only at this time (ie @streetdata.com.au).
Email to SMS to a single number(s) is unaffected: @streetdata.com.au
NOTE: If you send via @e2s.streetdata.com.au then you are unaffected by this issue.
API, and web portal sending are unaffected by this issue.
This has been escalated as critical internally and we are investigating a fix.
