How to Secure Your Business Email from Common Spam Filters

Updated 2026-07-01 · Hosting Reviews

Getting your business email to secure business email from spam starts with a solid foundation: a proper domain name, reliable hosting, and correctly configured DNS records. Below is a no‑fluff guide that walks you through picking a host, registering a domain, and setting up a professional email that stays out of the junk folder.

1. Pick the Right Hosting Plan for Email and Websites

For a small business, shared hosting is usually enough. It costs roughly $3‑$10 per month and includes the tools you need for both a website and email. If you expect rapid growth or need more resources, a cloud or VPS plan (around $10‑$30 per month) gives you extra CPU and RAM.

Key features to look for:

• Built‑in email accounts (POP/IMAP)
• Spam‑filtering tools (e.g., SpamAssassin, DKIM)
• Free SSL for the website and mail subdomains
• One‑click WordPress or site‑builder installation

Hostinger offers a beginner‑friendly package that includes all of the above, plus an intuitive control panel that makes DNS tweaks painless.

2. Register a Professional Domain Name

Your domain is the first impression. Choose a short, brand‑relevant name ending in .com or another familiar TLD. When you register through Hostinger, you often get a free domain for the first year, which keeps initial costs low.

Steps:

1. Search for an available domain that matches your business name.
2. Add it to the cart and select the registration period (1‑5 years).
3. Complete checkout; the domain will appear in your Hostinger dashboard.

Remember that renewal rates are higher than the introductory price, so budget for the long‑term cost.

3. Set Up DNS Records for Email Deliverability

Proper DNS configuration is the backbone of keeping your messages out of spam folders. You need three main records:

• MX (Mail Exchange) – Directs incoming mail to your host’s mail server.
• SPF (Sender Policy Framework) – Lists the servers authorized to send mail on your domain’s behalf.
• DKIM (DomainKeys Identified Mail) – Adds a cryptographic signature to outgoing messages.

In Hostinger’s control panel:

1. Go to DNS Zone for your domain.
2. Add the MX record provided by your hosting plan (usually something like mail.yourdomain.com).
3. Insert the SPF TXT record – a common format is v=spf1 a mx ip4:YOUR.SERVER.IP ~all.
4. Enable DKIM from the email settings; Hostinger will generate the TXT record for you.

After propagation (usually under an hour), test your setup with tools like MXToolbox.

4. Create and Secure Your Business Email Account

Now that DNS is ready, create the actual mailbox:

1. Log into Hostinger’s Email Accounts section.
2. Click “Create New Account”, choose a username (e.g., info@yourdomain.com), and set a strong password.
3. Enable the built‑in spam filter and, if available, add a custom whitelist for important contacts.

To further reduce spam chances:

• Use two‑factor authentication (2FA) on the email web client.
• Regularly update passwords and avoid reusing them elsewhere.
• Consider a third‑party spam‑filter service if you handle large volumes.

5. Connect Your Email to a Mail Client or Webmail

Most businesses prefer a familiar client like Outlook, Gmail, or Apple Mail. Configure the client with the following settings:

• Incoming server: mail.yourdomain.com (IMAP, SSL, port 993)
• Outgoing server: mail.yourdomain.com (SMTP, SSL, port 465)
• Username: full email address
• Password: the one you set earlier

Hostinger’s control panel provides a quick “Configure Email Client” button that fills in these details automatically.

6. Test and Maintain Deliverability

Send a test message to a personal Gmail or Outlook account and check the inbox vs. spam folder. If it lands in spam, double‑check your SPF/DKIM records and make sure your sending IP isn’t on any blacklists.

Monthly maintenance tasks:

• Review spam filter logs for false positives.
• Renew your domain before it expires to avoid email disruption.
• Update passwords and 2FA settings.

By keeping DNS records tidy and using Hostinger’s built‑in tools, you’ll keep your business email reliably delivered.

FAQ

Do I need a separate hosting plan just for email?

No. Most shared and cloud hosting packages include email accounts. Choose a plan that offers spam‑filtering and enough mailbox storage for your needs.

Can I use a free email service like Gmail with my domain?

Yes, you can forward mail to Gmail, but you lose full control over SPF/DKIM and may increase spam risk. Hosting the mailbox on your domain (via Hostinger) gives you better deliverability.

What if my emails still end up in spam after setting SPF and DKIM?

Check the sending IP reputation, avoid using URL shorteners, and ensure the email content isn’t overly promotional. Adding a DMARC record adds another layer of authentication that many receivers respect.
