With funnelizer, you can host (map) your own custom domain for your marketing funnels rather than use the system generated one that includes your username. This is highly recommended for branding purposes and with online marketing these days, some platforms are finicky with links that may be similar to others, marking them as spam.
The number of custom domains that you can host depends on your membership level. The Basic level can host 1 custom domain, Professional can host 2, and Premium can host up to 5 custom domains.
There is step by step instructions under your funnelizer settings as well as a video tutorial under your website tab > funnelizer.
You can also find this training as well as further training on the funnelizer under your training tab > my training library > membership courses > funnelizer
