Do I need a custom domain and business email before I launch, or is a .netlify or Vercel URL fine for testing?

The short answer

For validation and sharing in your own circle, a free subdomain is completely fine and nobody serious will judge you for it. The moment you're cold-emailing strangers or running ads, buy the domain and set up a matching business email, because a Gmail address and a random URL quietly kill trust with people who don't know you. A domain costs less than a coffee run, so buy it early but don't wait on it to start.

Why we picked it This lays out plainly what a custom domain actually buys you (credibility, a name you own, and business email at your own name) versus a free subdomain like yourapp.vercel.app. Read it to understand why the domain matters, then trust your own judgment: for a landing page you are only sharing with a handful of test users, the free URL is genuinely fine, and buying a domain is a ten minute job you can do the day you go public.

Custom Domains: Why You Need One and How To Get Started

From HubSpot by Lauren Farrell About 8 to 10 minute read

  • A custom domain is the one asset you own outright, while a free subdomain lives on someone else's brand and can change under you.
  • A business email at your own domain ([email protected]) reads as more trustworthy than a Gmail address to customers and investors.
  • The one real reason to buy early is to lock in the exact name you want before someone else registers it, not because a test URL is somehow unsafe.

Why we picked it Most registrars hook you with a cheap first year and quietly triple the renewal, which is exactly the trap a bootstrapped founder does not need. Cloudflare Registrar sells domains at cost with zero markup, so what you pay is what the registry and ICANN charge, and the renewal price does not jump on you later. It bundles free WHOIS privacy and DNS, so there is nothing extra to buy on top.

Cloudflare Registrar

From Cloudflare by Cloudflare

  • At-cost pricing with no markup means the same low price at registration and at renewal, so no surprise year-two bill.
  • Free WHOIS privacy and DNS are included, so you are not upsold on the basics.
  • You must run your domain on Cloudflare's nameservers, which is fine for most founders but worth knowing before you commit.
