Zoho Mail: DKIM Selector & SPF Setup

Zoho Mail DKIM setup

Zoho Mail Admin → Domains → your domain → Email Configuration → DKIM. Add a selector (commonly zoho), generate the key, publish the TXT record Zoho shows at <selector>._domainkey.yourdomain.com, then verify.

Zoho lets you choose the selector name — if zoho shows nothing below, check your admin panel for the selector you actually created. EU-hosted accounts may use include:zohomail.eu in SPF.

Zoho Mail SPF record

Your SPF TXT record on the root domain must contain include:zohomail.com. A minimal correct record: v=spf1 include:zohomail.com ~all. Stacking multiple ESPs? Each include costs DNS lookups against the limit of 10 — count yours here.

Verify all three pillars

DKIM alone doesn't inbox. Run the full domain grade to confirm SPF, DMARC, MX and blacklist status in one shot — Gmail and Microsoft require alignment across all of them for cold outreach in 2026.
