How to Connect a Custom Domain to Your SaaS App Landing Page
Updated 2026-06-23 · Hosting Reviews
Getting a SaaS landing page live means you need three things: a domain name, a hosting plan that can serve your page fast, and a platform to build the page. In this guide we’ll walk you through how to connect custom domain to saas landing page using cost‑effective tools and why Hostinger is a solid choice for beginners and small startups.
What You Need Before You Start
Before you dive into the technical steps, gather these basics:
- A domain name you own (or a new one you plan to buy).
- A hosting account that supports SSL and can run your chosen site builder or CMS.
- The landing‑page builder or framework you’ll use – WordPress with a landing‑page theme, a static‑site generator, or a drag‑and‑drop builder.
All three can be obtained from a single provider, which simplifies billing and support. Hostinger offers bundled domain + hosting packages that start in the low‑cost range.
Choosing the Right Hosting Type
For a startup or SaaS landing page you don’t need massive resources, but you do need reliability and speed. Here’s a quick comparison:
| Option | Typical Cost | When It Fits |
|---|---|---|
| Shared Hosting | $3‑$10/month | Small budgets, low traffic, beginner-friendly. |
| Cloud Hosting | $10‑$20/month | Scalable traffic, better isolation, slightly higher performance. |
| VPS | $15‑$30/month | More control, custom server configs, predictable performance. |
If you’re launching a single‑page site with a signup form, shared hosting is usually sufficient. As traffic grows, you can upgrade to cloud or VPS without moving the domain.
Picking a Platform for Your Landing Page
Two common routes are:
- WordPress + a conversion‑focused theme. One‑click installs are offered by most hosts, including Hostinger. You get plugins for forms, analytics, and SEO without coding.
- Website Builder (e.g., Hostinger’s Zyro or Wix). Drag‑and‑drop editors let you craft a page in minutes, ideal for non‑technical founders.
Both options work with a custom domain, but WordPress gives you more flexibility for future growth (blog, docs, support portal). A builder is quicker to launch if you just need a clean sign‑up page.
Step‑By‑Step: Connect Custom Domain to SaaS Landing Page
Follow these steps to get your domain pointing at your new landing page.
- Buy or transfer a domain. If you don’t have one, register it through Hostinger or another registrar. Keep note of the domain’s DNS management console.
- Set up hosting. Choose a shared plan from Hostinger if you’re on a tight budget. During signup, you’ll be prompted to link a domain – select the one you just registered.
- Install your platform. In Hostinger’s control panel, click “One‑Click Install” and pick WordPress, or launch the Zyro builder. The installer will automatically configure the web root.
- Configure DNS. If you bought the domain elsewhere, log into that registrar and add two records:
- A record pointing to the IP address provided by Hostinger (usually found in the hosting dashboard).
- Alternatively, use Hostinger’s nameservers (ns1.hostinger.com, ns2.hostinger.com) and let them manage the records.
- Enable SSL. Hostinger provides a free SSL certificate that you can activate with one click. This secures the connection and boosts conversions.
- Build the landing page. Use a conversion‑optimized theme (e.g., Astra, Elementor) or the builder’s templates. Include a clear headline, benefit bullets, and a sign‑up form (Mailchimp, HubSpot, or a simple email capture).
- Test and publish. Open your domain in a private browser window, verify the page loads over HTTPS, and test the form submission. Once happy, publish the page.
That’s it—your custom domain now points to a live SaaS landing page.
Speed, Security, and Ongoing Costs
Even a simple landing page benefits from basic performance tweaks:
- Enable caching (Hostinger includes LiteSpeed cache on most plans).
- Compress images and serve them in WebP format.
- Use a CDN – Hostinger offers a free CDN on many plans.
Security basics include keeping WordPress/plugins updated, using a strong admin password, and enabling two‑factor authentication. Because renewal rates can be higher than introductory offers, budget for $5‑$15 per month after the first year.
FAQ
Do I need a separate email service for my domain?
Hostinger includes custom email accounts (e.g., hello@yourdomain.com) on most plans. For higher volume or advanced features, you can connect Google Workspace or Microsoft 365.
Can I switch from shared to cloud hosting without moving the domain?
Yes. Most hosts, including Hostinger, let you upgrade the plan while keeping the same domain and DNS settings. The IP address may change, but the transition is seamless.
What if I want to add a blog later?
Starting with WordPress makes it easy to add a blog under the same installation. You can create a new “Posts” section and keep the landing page as the homepage.
