In order to whitelabel your Fiitfu messages we would need to know who hosts your domain presently.
Once we know this, we will send your DNS settings and then you would need to add these fields as NEW DNS records.
The types of these 3 records are all CNAME.
We would then "validate" your email as a whitelabel.
If we know your host, we can instruct you on how to do the above.
The cost to do this is a one time fee of $50.00 USD. Please click on the following link to make the purchase: http://fiitfu.com/product/whitelabel/
Please Note: the login at checkout is separate from your Fiitfu login and can be bypassed by purchasing as a guest
