Sending emails with Gmail or Hotmail using SQL Server Agent

Question

I've created an Operator with my personal gmail account and I've created an alert job to alert me whenever Tracked transactions/sec rises above 10.

I've ran this test query to test the emails system

USE AdventureWorks2012
Go

CREATE TABLE NuggetDemos.t1(c1 int)
GO

DECLARE @counter int
SET @counter = 1
WHILE (@counter <= 20000)
   BEGIN
	PRINT @counter

	INSERT NuggetDemos.t1
	   SELECT @counter

	SET @counter += 1
   END
GO

SELECT * FROM NuggetDemos.t1

But alas I'm not receiving any notifications. What am I doing wrong here?

Do I need to setup a profile using Database Mail? if so, what are the smtp details of either gmail or hotmail?
