How to add a custom domain with SSL
Custom domains are available on the Agency and Business plans. Please note, you must use a subdomain. You can’t add a custom domain on the root (example.com) or on www.example.com, so don’t include the ‘www’.
An example of the correct format would be: proposals.example.com
If you have trouble with any part of the process, be sure to contact us on support@nusii.com
Go to Settings and click Custom Domain. Type the address you want (for example proposals.yourwebsite.com) and click Add Custom Domain.
Then go to the DNS settings of https://yourwebsite.com and create a CNAME record pointing ‘proposals’ (or any other subdomain you want, e.g. quotes) to ‘secure.nusii.com.’ (For lots of providers you have to add a dot after .com)
Here is an example of the private DNS settings for michaelkoper.com

‘secure.nusii.com’ is the value and ‘proposals’ is my host/name.
After you have this configured, click the Verify button on the Custom Domain page. DNS changes can take up to 24 to 48 hours to come through, so if it won’t verify straight away, try again later. If it still won’t verify, drop us a line and we’ll make sure everything is as it should be.
Once it’s live, your proposals open at https://proposals.yourwebsite.com/p/…. Links you sent before keep working.
