Table structure is 

EmployeeId, EmployeeName, Employee email address

Data is like this:

FOR XML PATH() is good solution for SQL Server:

WITH x AS (
    SELECT '[email protected]' AS mail
    UNION
    SELECT '[email protected]'
    UNION
    SELECT '[email protected]'
)
SELECT
    STUFF((SELECT
        mail + ','
    FROM
        x
    FOR XML PATH(''), TYPE, ROOT).value('root[1]', 'nvarchar(max)'), 1, 1, '')

Query above returns @example.com,[email protected],[email protected],.

In your case query would look like (could contain errors):

SELECT
  EmployeeId, 
  EmployeeName, 
  (SELECT
        STUFF((SELECT
            [e.email address] + ','
        FROM
            employees e
        WHERE
                e.EmployeeId = EmployeeId
        FOR XML PATH(''), TYPE, ROOT).value('root[1]', 'nvarchar(max)'), 1, 1, '')) AS mails
   FROM
     employees

You can try with COALESCE

DECLARE @listStr VARCHAR(MAX)

select @listStr = COALESCE(@listStr+',','') + Employee_email_address from table1 where EmployeeId = @EmployeeId
select @listStr

Query above will return @example.com,[email protected],[email protected],

You can try this: SQL Fiddle

SELECT SUBSTRING(
(SELECT ';' + e.EmailAddress
FROM Employee e
FOR XML PATH('')),2,8000) AS CSV

From SQL Server 2005 upward. See more here

You can use cursor for that.

DECLARE @email VARCHAR(256) 
DECLARE @EmailCollection VARCHAR(MAX)

DECLARE db_cursor CURSOR FOR  
SELECT Email 
FROM tableName

OPEN db_cursor   
FETCH NEXT FROM db_cursor INTO @email   

WHILE @@FETCH_STATUS = 0   
BEGIN   

       SET  @EmailCollection = @EmailCollection + @email + ';'
       FETCH NEXT FROM db_cursor INTO @email   
END   

CLOSE db_cursor   
DEALLOCATE db_cursor

And at the end you can return @EmailCollection
