How can I force new lines in alert emails?

We want to use Sumo Logic Alerts to send notifications and have the message easy to read. 
I have message nicely formatted in the log
      "@t":"2021-02-19T03:24:20.4443314Z",

• "@mt":"Sheet Records 5, Successful 0, Failed 5
  Failed Records:
  TSA 222 Galileo PNR0, ticket 1234Ticket0: ItineraryId: 222 not found
  TSA 224 Galileo PNR2, ticket 1234Ticket2: ItineraryId: 224 not found
  TSA 223 Galileo PNR1, ticket 1234Ticket1: ItineraryId: 223 not found
  TSA 226 Galileo PNR4, ticket 1234Ticket4: ItineraryId: 226 not found
  TSA 225 Galileo PNR3, ticket 1234Ticket3: ItineraryId: 225 not found
  ",
• "@l":"Error",
  

but in email they all are shown as one string 

• {​"timestamp":1613705060444,"log":{​"@t":"2021-02-19T03:24:20.4443314Z","@mt":"Sheet Records 5, Successful 0, Failed 5\nFailed Records:\nTSA 222 Galileo PNR0, ticket 1234Ticket0: ItineraryId: 222 not found\nTSA 224 Galileo PNR2, ticket 1234Ticket2: ItineraryId: 224 not found\nTSA 223 Galileo PNR1, ticket 1234Ticket1: ItineraryId: 223 not found\nTSA 226 Galileo PNR4, ticket 1234Ticket4: ItineraryId: 226 not found\nTSA 225 Galileo PNR3, ticket 1234Ticket3: ItineraryId: 225 not found\n","@l":"Error","SourceContext":"TsaNotesApi.ActualRefundsNotes.ActualRefundsNotesCreator","ActionId":"cf326e58-15c0-47c6-8bcc-02614320f97e","ActionName":"TsaNotesApi.Controllers.NotesController.LoadActualRefundsNotes
  

How can I create the email to be better formatted ?
