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

Lauren Farrell · HubSpot Free Beginner

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.

• 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.
