Free Business Email for Your Hostinger Domain

Mail records go wherever the domain's DNS is managed. Hostinger shows the domain's nameservers at the top of the DNS records tab, so check there first:

Hostinger lets you edit its DNS zone even when the nameservers point elsewhere, but its help center says those changes only take effect once you switch the nameservers back to Hostinger. So if you edit in the wrong place, nothing happens. Just bought the domain? I bought a domain, how do I get email on it? covers the first hour.

Set up the mail side first, so the mailboxes exist before the first message arrives and you have the exact values to copy.

Hostinger's help center says a Business Email free trial is included with its web, cloud and agency hosting plans, with 1 GB of storage per mailbox. The trial runs 1 month on monthly billing, 3 months on quarterly billing and 1 year on yearly or longer billing, and renewing the hosting plan does not extend it. When it ends, Hostinger says it renews automatically as a paid Business Starter plan if you have a saved payment method. We found no mention of a mailbox bundled with a domain-only purchase (checked 12 November 2026).

If you already use a Hostinger mailbox:

• Copy the mail you want to keep first. The Mailbux migration tool copies existing email from any IMAP provider into Mailbux, and it works on every plan, Free included.
• Check the trial's renewal in your Hostinger account so it does not turn into a paid plan you no longer use.
• Note what else sends mail for the domain, such as a newsletter tool or a contact form that sends through a Hostinger mailbox. You need it for the SPF step.

Hostinger's DNS editor has a Manage DNS records card at the top and the list of existing records below it. Add the new MX first, then delete the old ones.

SPF tells receiving servers that Mailbux may send mail for your domain. Hostinger's own help page says a domain must have only one SPF record. Look in the records list for a TXT record that starts with v=spf1. Hostinger Email uses v=spf1 include:_spf.mail.hostinger.com ~all.

• Nothing sends through Hostinger mail any more: edit that record with the pencil icon and replace its value with v=spf1 include:msg25.com ~all.
• Something still sends through a Hostinger mailbox: keep both in one line, v=spf1 include:_spf.mail.hostinger.com include:msg25.com ~all.
• No SPF record yet: add one with the steps below.

DKIM is optional and improves deliverability. In Mailbux open Domains, then Open DNS setup, copy the DKIM TXT record and add it in Hostinger as a TXT record with the Name Mailbux shows. If it does not resolve after a few hours, check that your domain was not typed twice in the Name field.

DMARC is optional too. Add a TXT record with Name _dmarc, start with a monitoring policy and read the reports before tightening it. Reading DMARC reports in plain English explains what you will receive.

• The leftover priority 5 record. Hostinger Email's mx1.hostinger.com has priority 5, and a lower number wins. If you add my.mailbux.com at 10 and forget to delete mx1, mail keeps going to Hostinger.
• Quick setup. The Quick setup box connects Shopify, Google Workspace and Google site verification in one click. It does not cover other email hosts, so add the records by hand, and do not run the Google Workspace option unless you want Google's MX records.
• Import with Replace. Importing a zone file in Replace mode removes every existing record, website and email included. Use Export first as a backup, and Append if you import at all.
• Restoring DNS history. The DNS history tab restores an older version of the whole zone. Restoring a snapshot from before your change brings back the old mail records.
• Waiting time. Hostinger says DNS changes can take up to 24 hours, and in rare cases up to 72. Most show sooner; wait before redoing anything.
• Website records. Leave the A and CNAME records that run your site alone. Email without changing nameservers explains why mail records do not affect the site.

1. Run nslookup -type=MX yourdomain.com and nslookup -type=TXT yourdomain.com (or dig). You should see only my.mailbux.com for MX and one v=spf1 line that includes msg25.com.
2. In Mailbux, Domains, then Open DNS setup checks the records for you; choose Re-check now after editing.
3. Send a test from a personal address to your new mailbox and reply from Mailbux webmail. In the reply's headers you should see spf=pass.
