Zoho Mail SPF, DKIM and DMARC setup

Zoho Mail needs v=spf1 include:zohomail.com ~all at the root of your domain, or include:one.zoho.com if you use several Zoho services. DKIM is a TXT record at <selector>._domainkey with a selector you choose in the Admin Console (Zoho's example is zoho), switched on after it verifies. Then add DMARC at _dmarc, starting with p=none.

Troubleshooting

Common Zoho Mail errors and fixes

For cold email

Mailboxes that come with the DNS records done

If the domain is for cold outreach, keep Zoho Mail on your main domain and send from separate domains. Outreach2day buys the domains, publishes SPF, DKIM and DMARC, creates the mailboxes and starts warm-up, then sends your campaigns from its own sequencer or exports the mailboxes to Instantly or Smartlead.

Questions

What is the Zoho Mail SPF record?

v=spf1 include:zohomail.com ~all at the root of the domain. If you use several Zoho services, Zoho suggests include:one.zoho.com. Accounts in other data centers take their values from the Admin Console.

What DKIM selector does Zoho Mail use?

The one you type when you add DKIM in the Admin Console; Zoho's example is zoho, which makes the record zoho._domainkey. Enter yours in the checker above if it differs.

Why does Zoho DKIM not verify?

The key was cut off when copied, the host name has the domain twice, or DNS has not updated yet. Fix the record and click Verify again after the TTL passes.

Can I send cold email from Zoho Mail?

Keep Zoho for company mail on the main domain. Cold outreach usually runs from separate domains with their own warmed mailboxes, so the company domain keeps its reputation.
