What include:_spf.mail.hostinger.com expands to live, 5 Nov 2026
v=spf1 include:relay.mail.hostinger.com include:relay.mailchannels.net ~all
Counted as RFC 7208 §4.6.4 does: the include itself plus every nested include, a, mx, ptr, exists and redirect. Includes can change at any time; this page re-measures daily.
Adding it next to another service
A domain has exactly one SPF record, so add the include to the record you already have. With Google Workspace, for example:
v=spf1 include:_spf.google.com include:_spf.mail.hostinger.com ~all
How it affects DMARC
DMARC passes when SPF or DKIM passes for a domain aligned with your From address. With Hostinger Email sending from your domain, its include lets SPF pass and align; DKIM signing with your domain gives you a second, forwarding-proof way to pass.
