You don’t have to transfer your domain name to use it with another server/web hosting – just connect the nameservers to the web hosting you want to use. Or, alternatively, if you like their web hosting, you can get a website builder to install there, depending on the server specifications. Check out UltimateWB – the promo version would work great for you; if you want a mailing list app, use the lite version. You can also get web hosting at UltimateWB too for under $5/month, and get free SSL and software installation service, so that is also a good option – you can use it with your Namecheap domain without transferring it out by just updating the nameservers.
When registering a new domain name, or making registration changes to a domain, your domain name is locked to that registrar for 60 days – after that you are free to transfer your domain to another company if you’d like, per ICANN rules.
