Zoho Mail email authentication
Zoho’s business mailbox service, popular as a low-cost Google Workspace alternative.
SPF record
Add Zoho Mail to your domain's SPF record with this include:
include:zohomail.com
A complete record for a domain sending only through Zoho Mail:
v=spf1 include:zohomail.com ~all
What it costs you
2 of your 10 DNS lookups. The include: itself costs one, and Zoho Mail's record chains to 1 more.
Behind it are 8 IP ranges.
Live record
This is what zohomail.com published when this page was generated:
v=spf1 include:spf.zohomail.com -all
DKIM
Enable DKIM inside Zoho Mail 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 Zoho Mail 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.
