Why is DDL command not executing stored procedure

I'm trying to write a DDL trigger that will send an email if someone tries to a drop a database.  I have dropped my sample code below.  The trigger works in that the Rollback prevents the database from being dropped, but the stored procedure does not appear to run at all and so a message isn't sent.  The same store procedure does work on a similar DDL script for DROP TABLE.

USE [master]
GO

/****** Object:  DdlTrigger [ddl_trig_database]    Script Date: 10/29/2017 11:13:57 PM ******/
SET ANSI_NULLS OFF
GO

SET QUOTED_IDENTIFIER OFF
GO

alter TRIGGER [ddl_trig_database]  
ON ALL SERVER  
FOR Drop_DATABASE  
AS  
   DECLARE @eventData XML,
        @otext VARCHAR(MAX),
        @edate DATETIME,
            @Msg varchar(max)

set @edate=GETDATE()
SET @eventData = EVENTDATA()      
select  @otext=@eventData.value('data(/EVENT_INSTANCE/ObjectName)[1]', 'SYSNAME')      

set @msg = ' Delete attempt on database ' + convert(varchar(26),@edate,100) + '  ' + @otext

exec demo.dbo.SendInternetEmail 'RECIPIENT@gmail.com', 'Dropped database', @msg, 'SENDER@gmail.com'
rollback

GO

SET ANSI_NULLS OFF
GO

SET QUOTED_IDENTIFIER OFF
GO

ENABLE TRIGGER [ddl_trig_database] ON ALL SERVER
GO

Are you getting any error ? or your sp <demo.dbo.SendInternetEmail> is not getting called ?

Pls see if this works -

USE [master]
GO

/****** Object:  DdlTrigger [ddl_trig_database]    Script Date: 10/29/2017 11:13:57 PM ******/
SET ANSI_NULLS OFF
GO

SET QUOTED_IDENTIFIER OFF
GO

alter TRIGGER [ddl_trig_database]   
ON ALL SERVER   
FOR Drop_DATABASE   
AS   
BEGIN

   DECLARE @eventData XML,
        @otext VARCHAR(MAX),
        @edate DATETIME,
            @Msg varchar(max)

set @edate=GETDATE()
SET @eventData = EVENTDATA()       
select  @otext=@eventData.value('data(/EVENT_INSTANCE/ObjectName)[1]', 'SYSNAME')       

set @msg = ' Delete attempt on database ' + convert(varchar(26),@edate,100) + '  ' + @otext
rollback
exec demo.dbo.SendInternetEmail 'RECIPIENT@gmail.com', 'Dropped database', @msg, 'SENDER@gmail.com'

END

I had been trying to delete the test database from the management studio window and didn't get any errors.  I ran a Drop Database command from the query window and received an error about ANSI settings.  I removed the lines:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
 
I then started receiving blank email messages and was able to correct that by changing the @otext line to:

select   @otext=@eventData.value('data(/EVENT_INSTANCE/TSQLCommand/CommandText)[1]', 'VARCHAR(MAX)')
