In order to publish a website or newsletter, we may request access to your Domain Name Service provider, or "DNS". There are many DNS providers, and they all do mostly the same thing.
For new domains
We recommend purchasing your domain through Namecheap. It has pretty good pricing, great delegation features (for granting Snapmarket access), and while there are myriad "add-ons" when buying your domain, you likely won't need any of them if you're a Snapmarket Project Pro or Partner subscriber.
For existing domains
If you already have a domain purchased and ready for use, you'll need to grant access to the Snapmarket team. Unless there is an overt problem with your DNS provider, there shouldn't be any need to switch.
