Hostinger Email email authentication
Hostinger’s bundled business email.
SPF record
Add Hostinger Email to your domain's SPF record with this include:
include:_spf.mail.hostinger.com
A complete record for a domain sending only through Hostinger Email:
v=spf1 include:_spf.mail.hostinger.com ~all
What it costs you
3 of your 10 DNS lookups. The include: itself costs one, and Hostinger Email's record chains to 2 more.
Behind it are 7 IP ranges.
Live record
This is what _spf.mail.hostinger.com published when this page was generated:
v=spf1 include:relay.mail.hostinger.com include:relay.mailchannels.net ~all
DKIM
Enable DKIM inside Hostinger Email and publish the selector record it generates. DKIM matters more than SPF for deliverability, because a DKIM signature survives forwarding while SPF does not — see how selectors work.
DMARC
Neither SPF nor DKIM protects the address your recipients actually see until DMARC ties them
to it. Once Hostinger Email is authenticating, publish a DMARC record — start at
p=none with a reporting address and
tighten from there.
Check it worked
DNS changes take minutes to hours to propagate. Once published, run the domain through the checker — it resolves the full include chain and reports the real lookup count.
