Count statistics in sql

Hi,

I have this table looking like this:
User generated image
I would like to count the how many times each event occurs based on each newsletter. So that I get a result like this:
Processed Delivered   Open  Click  Deferred newsletterID
25                22              15       3         3               9

How can I achieve that with an sql query?

I can only assume that the data shown above is not the complete set to produce the results you are looking for since there are are fewer processed and delivered events, only 2 open and click events shown, no deferred events and the number of newsletter ids shown are six and not nine. If so, can you produce the entire set of data in a format that can be used to re-create the table so we can test(i.e. not a picture) such as a text or excel file. Even better would be to show the table create with the insert statements that populated that data.

Yes, the image shows only a fraction of the data. Here is the insert query for the table:

INSERT INTO [dbo].[customerGroupMailStatistics]
           ([customerID]
           ,[newsLetterID]
           ,[event]
           ,[url]
           ,[response]
           ,[timestamp]
           ,[tID]
           ,[email])
     VALUES
           (<customerID, int,>
           ,<newsLetterID, int,>
           ,<event, nvarchar(50),>
           ,<url, nvarchar(300),>
           ,<response, nvarchar(500),>
           ,<timestamp, nvarchar(50),>
           ,<tID, int,>
           ,<email, nvarchar(200),>)
GO

Thanks for help!

Here is a create by the way so it gets faster with testing:
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[customerGroupMailStatistics](
	[id] [int] IDENTITY(1,1) NOT NULL,
	[customerID] [int] NULL,
	[newsLetterID] [int] NULL,
	[event] [nvarchar](50) NULL,
	[url] [nvarchar](300) NULL,
	[response] [nvarchar](500) NULL,
	[timestamp] [nvarchar](50) NULL,
	[tID] [int] NULL,
	[email] [nvarchar](200) NULL,
 CONSTRAINT [PK_customerGroupMailStatistics] PRIMARY KEY CLUSTERED 
(
	[id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

What really is needed is to see all of the actual data. Can you just post the results of this query (in a text file will do)?
select id, customerid, newsletterid, event from [dbo.customerGroupMailStatistics] order by 1;
Here you go!
groupmail.csv
With some 35,000 records, I am assuming there will be many more than 25 processed events (the same being true for the other event values). Are the results you initially showed as wanting to get just an example or based on some filter applied to limit the number of rows?
SELECT    
           SUM(CASE WHEN event = 'Processed' THEN 1 ELSE END) AS Processed
           ,SUM(CASE WHEN event = 'Delivered' THEN 1 ELSE END) AS Delivered
           ,SUM(CASE WHEN event = 'Open' THEN 1 ELSE END) AS Open
           ,SUM(CASE WHEN event = 'Click' THEN 1 ELSE END) AS Click
           ,SUM(CASE WHEN event = 'Deferred' THEN 1 ELSE END) AS Deferred
           ,[newsLetterID]
GROUP BY
           [newsLetterID]
