Wix email authentication
Website builder that sends store and form mail on your behalf.
SPF record
Add Wix to your domain's SPF record with this include:
include:_spf.wix.com
A complete record for a domain sending only through Wix:
v=spf1 include:_spf.wix.com ~all
What it costs you
4 of your 10 DNS lookups. The include: itself costs one, and Wix's record chains to 3 more.
Live record
This is what _spf.wix.com published when this page was generated:
v=spf1 include:%{i}._ip.%{h}._ehlo.%{d2}._spf.42.wix.com include:%{i}._ip.%{h}._ehlo.%{d2}._spf.84.wix.com include:%{i}._ip.%{h}._ehlo.%{d2}._spf.96.wix.com -all
DKIM
Enable DKIM inside Wix 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 Wix 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.
