In subject line of email I want @Subject to return "'Submission at 10/03/2019 22:46:34".
Concatenating with + and quotes isn't working. How is it done?
DECLARE @Recipients   varchar(max)    = 'polkadot@email.com',         @Subject   varchar(max)                   = 'Submission at ',         @Body    varchar(max)                      = null,         @ReportDate          varchar(50)        = FORMAT(GETDATE() , 'dd/MM/yyyy HH:mm:ss'),         @emailbody varchar(max)                = 'The attached excel contains stuff';

EXECUTE msdb.dbo.sp_send_dbmail
   @Recipients             = @Recipients,
   @Subject                 = @Subject + ' ' + FORMAT(GETDATE() , 'dd/MM/yyyy HH:mm:ss'),
   @Body                     = @emailbody,
   @file_attachments   = @FileShare2;

Odd. When I tried it without any of the SendMail part, it worked:
DECLARE @Recipients varchar(max) = 'polkadot@email.com', @Subject varchar(max) = 'Submission at ', @Body varchar(max) = null, @ReportDate varchar(50) = FORMAT(GETDATE() , 'dd/MM/yyyy HH:mm:ss'), @emailbody varchar(max) = 'The attached excel contains stuff';

SET @Subject = @Subject+ ' ' + FORMAT(GETDATE() , 'dd/MM/yyyy HH:mm:ss'); PRINT @Subject;
Result:
Submission at 11/03/2019 00:58:21

For SQL 2008 and above you can use +=
SET @Subject += ' ' + FORMAT(GETDATE() , 'dd/MM/yyyy HH:mm:ss');

I'd recommend that you get out of the habit/crutch of using FORMAT. Yeah... it's nice and easy but it's a bad habit until they fix the major performance issues it has. Justifying it's use for a one-off low-row-count is a poor justification for not practicing faster methods and just leads to a "Death of a Thousand Cuts" in the database over time.

The issue is that you're trying to do a calculation for a parameter and pass the parameter at the same time. You have to do the calculation first as a variable and then use the variable as a parameter. It's just the way procs work.
