Redirect www link to specific page/post

We sent out a marketing email with a bad link:
http://www.newbirthoffreedom.org/cookout
It should have been:
http://newbirthoffreedom.org/giving/campfire-cookout/
or just
http://newbirthoffreedom.org/cookout
The www. is creating the problem.
How can I fix this to redirect the bad link to the right link?

I’ve tried Redirect 301 www.newbirthoffreedom.org/cookout /cookout
and several variations, including the entire url, restarting apache, etc, with no luck.

My htaccess looks like this:

RewriteEngine On
RewriteBase /

#uploaded files
RewriteRule ^(.*/)?files/$ index.php [L]
RewriteCond %{REQUEST_URI} !.*wp-content/plugins.*
RewriteRule ^(.*/)?files/(.*) wp-includes/ms-files.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteCond %{REQUEST_URI} ^.*/wp-admin$
RewriteRule ^(.+)$ $1/ [R=301,L]

<IfModule mod_security.c>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>

# BEGIN WordPress
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule . - [L]
RewriteRule  ^([_0-9a-zA-Z-]+/)?(wp-.*) $2 [L]
RewriteRule  ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

# END WordPress

Any help is much appreciated.
