Send specific message if no results available using sp_send_dbmail - sql

Question

I would like to have a specific message sent if no results are available. Right now if my job executes and there is nothing to report the email just show up blank.
SP is below
EXEC msdb.dbo.sp_send_dbmail
#profile_name = 'Mail_profile',
#recipients = 'myemail#somename.com',
#subject = 'Weekly',
#query = N'EXEC PTW.dbo.SP_Weekly',
#attach_query_result_as_file = 1,
#query_result_width = 150,
#query_result_header= 1,
#query_attachment_filename = 'Weekly.txt',
#importance = 'High',
#query_result_no_padding = 1,
#query_result_separator = ' ';
If there are no records available when this is ran, I would like to show No records available at this time
I have tried to insert an ISNULL before #query but this is something I'm stumped on. Any suggestions?
Would also like the message always show No records found for 'Yesterdays date'
Thinking id have to add dateadd(day, datediff(day, 0, getdate()), -1) somewhere in there but where?

declare #subject1 varchar(max)
declare #body1 varchar(max)
EXEC PTW.dbo.SP_Weekly
if ##rowcount=0
begin
set #subject1='No data or any message that suits you'
set #body1='some message'
EXEC msdb.dbo.sp_send_dbmail
#profile_name = 'Mail_profile',
#recipients = 'myemail#somename.com',
#subject = #subject1,
#importance = 'High',
#body=#body1,
#query_result_separator = ' ';
return
end
else
begin
EXEC msdb.dbo.sp_send_dbmail
#profile_name = 'Mail_profile',
#recipients = 'myemail#somename.com',
#subject = 'Weekly,
#query = N'EXEC PTW.dbo.SP_Weekly',
#attach_query_result_as_file = 1,
#query_result_width = 150,
#query_result_header= 1,
#query_attachment_filename = 'Weekly.txt',
#importance = 'High',
#query_result_no_padding = 1,
#query_result_separator = ' ';
end
