Launching a SaaS product means you need a reliable domain, professional email, and DNS records that point visitors and services to the right place. Below is a practical dns setup checklist new saas product site can follow to get online without wasting time or money.

1. Pick the Right Hosting & Platform

Before you touch DNS, decide where the site will live. For most SaaS landing pages or demo sites, a shared or cloud plan is sufficient. Here’s a quick compare‑and‑choose:

For the front‑end, WordPress works well for marketing pages, while a static site generator (like Hugo or Next.js) is lighter and faster. Hostinger offers one‑click WordPress installs, free SSL, and easy scaling, making it a solid pick for beginners.

2. Register a Professional Domain & Business Email

Choose a domain that reflects your product name and is easy to spell. Keep it short, avoid hyphens, and consider a .com or relevant TLD (e.g., .io for tech). When you register through Hostinger, you get a free domain for the first year with most plans.

Next, set up a business email address (e.g., support@yourproduct.com). This boosts credibility and keeps communications separate from personal inboxes. Hostinger bundles email hosting or you can link to a third‑party provider like Google Workspace – both work with the same DNS records.

3. Understand the Core DNS Records You’ll Need

DNS is the phone book of the internet. For a SaaS product site, you’ll typically configure four record types:

  1. A record – Points your domain (or subdomain) to an IPv4 address of your server.
  2. AAAA record – Same as A but for IPv6 (optional).
  3. CNAME record – Aliases one name to another (useful for www or pointing a subdomain to a SaaS platform like app.yourproduct.com).
  4. MX records – Direct email to your mail server; required for business email.

Most of the time you’ll only need an A record for the root domain, a CNAME for www, and MX records for email.

4. DNS Setup Checklist New SaaS Product Site – Step by Step

Follow these actions in order to avoid missing a critical piece.

  1. Buy the domain. Register through Hostinger or another registrar. Note the registrar’s control panel where DNS will be managed.
  2. Choose your hosting plan. Activate the plan, note the server IP address (you’ll find it in the hosting dashboard).
  3. Point the domain to the host.
    • Log into the domain’s DNS manager.
    • Add an A record for @ (the root) pointing to the server IP.
    • Add a CNAME record for www pointing to @ or directly to your domain.
  4. Set up business email.
    • If using Hostinger’s email, create the mailbox (e.g., support@yourproduct.com).
    • Add the MX records that Hostinger provides – usually something like mx1.hostinger.com with priority 10.
    • Optionally add SPF, DKIM, and DMARC records to improve deliverability.
  5. Enable SSL. In Hostinger’s control panel, turn on the free Let’s Encrypt SSL. This adds a TXT record for verification and updates your site to HTTPS.
  6. Test everything. Use dig or an online DNS checker to verify A, CNAME, and MX records propagate (usually under 30 minutes). Browse to https://yourproduct.com and send a test email.

Once these steps are confirmed, your site is live, secure, and ready for visitors.

5. Speed, Security, and Ongoing Maintenance

Even a simple SaaS landing page benefits from a few extra tweaks:

Keeping WordPress or your static site generator up to date prevents security holes. A regular audit of DNS records (remove unused subdomains, verify MX settings) also helps maintain a clean, professional presence.

FAQ

Do I need a separate hosting account for my SaaS backend?

Not necessarily for a simple demo or marketing site. You can host the front‑end on shared/cloud hosting and point API calls to a separate service (e.g., AWS Lambda). Keep DNS records separate for clarity.

Can I transfer an existing domain to Hostinger without downtime?

Yes. Change the domain’s nameservers to Hostinger’s after the transfer. DNS propagation may take up to 48 hours, but the site stays reachable as long as the old records remain active during the switch.

What if I outgrow the shared plan?

Hostinger lets you upgrade to cloud or VPS with a few clicks. Your DNS settings stay the same; only the server IP changes, which you update in the A record.
