Compiling condition across multiple worksheets to output 1 "solution". Also call out which worksheets(s) fit the condition

I am new to vba and struggling with trying to accomplish having a single overall email send out if any worksheet column L/M have a value below 1 and want it to call out which sheet (or sheets) had the value <1 in the email body or subject line. I have spent countless hours searching the web, but nothing so far has really worked for me. The MsgBox function is working fine, just having issues with compiling the results to 1 email naming which worksheet had the <1 value and 1 "solution" for the whole workbook, instead of having an email sent for every single worksheet that the conditions fit. Thank you in advance.

   Option Explicit
   Sub Main()
   Dim sh As Worksheet, i As Long

  For Each sh In ActiveWorkbook.Worksheets
   With WorksheetFunction
    If .CountIf(sh.Range("L3:L26"), "<1") > 0 Then
        Call SendReminderMail1
    Else
        MsgBox "Rotations NOT needed for """ & sh.Name & """."
    End If
    If .CountIf(sh.Range("M3:M20"), "<1") > 0 Then
        Call SendReminderMail2
    Else
        MsgBox "Functions are NOT needed for """ & sh.Name & """."
    End If
End With
  Next
  End Sub
  Sub SendReminderMail1()
