For Zoho Mail, publish a single SPF TXT record including Zoho’s servers: v=spf1 include:zohomail.com ~all (Zoho may specify a region-specific include). Combine it with any other senders in the same record, and pair with Zoho DKIM for DMARC alignment.
Add Zoho’s include to your one SPF record. If you already send through other services, merge their includes rather than creating a second SPF record.
SPF alone can fail DMARC on forwarding — enable Zoho DKIM (signed with your domain) so DMARC passes reliably on alignment.
