SPF, DKIM and DMARC for Hostinger Email

Short answer: Hostinger Email mail passes Gmail, Yahoo and Microsoft checks when you turn on DKIM with your own domain, add include:_spf.mail.hostinger.com to your one SPF record and publish a DMARC record at _dmarc (start with p=none). The exact records and clicks are below.

SPF	TXT at `@`	v=spf1 include:_spf.mail.hostinger.com ~all This include covers Hostinger's own mail relay and the MailChannels relay it sends through. Combine with your other senders →
DKIM	CNAME / TXT	Three CNAME records: `hostingermail-a._domainkey` → `hostingermail-a.dkim.mail.hostinger.com`, and the same for `hostingermail-b` and `hostingermail-c`.
DMARC	TXT at `_dmarc`	v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com Start with `p=none` and a mailbox you read, or a free report address that turns the reports into a dashboard; build your own.

Step by step

Domain on Hostinger nameservers? In hPanel → Emails pick the domain and use the automatic setup: Hostinger adds MX, SPF and DKIM for you. Then go straight to the DMARC step.
DNS somewhere else (Cloudflare, GoDaddy, your registrar)? Add two MX records at @: mx1.hostinger.com (priority 5) and mx2.hostinger.com (priority 10), and delete the old MX records.
Add the SPF include below to your one SPF record at @.
Add the three DKIM CNAME records exactly as listed (CNAME, not TXT).
Publish DMARC at _dmarc with p=none. The automatic setup does not add it.
DNS changes can take up to 24 hours; then check the domain below.

Mistakes that break it

Hostinger sells both Hostinger Email and Titan. Check your MX: mx1.hostinger.com means Hostinger Email, mx1.titan.email means Titan, and the records are different (see the Titan guide).
Two SPF records (say, an old one from your previous host plus Hostinger's) make SPF fail. Merge them into one.
Only hostingermail-a holds a key at the moment; -b and -c show an empty key. That is normal: add all three CNAMEs so key changes on Hostinger's side keep working.
Newsletters sent with Hostinger Reach need their own DKIM records on top of these.

Check that it worked

After the fix, keep an eye on it: free DMARC monitoring shows every service that sends mail as your domain and which ones fail, in plain English.

Rather not touch DNS? I set up SPF, DKIM and DMARC without breaking your other senders, with a before/after report.
