Why do emails from Zoho Mail land in Gmail spam?

Usually because the domain is not fully authenticated, the domain or IP has a weak reputation, or the content and sending pattern look like bulk mail. Add SPF, DKIM and DMARC for your domain as Zoho Mail's admin console guides you, send normal one-to-one email, and avoid mass sends from Zoho Mail. Most cases clear once DNS records are correct.

Gmail checks whether the sending server is allowed to send for your domain. Without an SPF record that includes Zoho, a DKIM signature from Zoho Mail and a DMARC record, Gmail is more likely to filter your mail. The Zoho Mail admin console shows the exact records to add and confirms when they are verified.

Reputation is the next factor. A new domain, a domain that sent spam in the past, or sudden high volume can all hurt delivery. Zoho Mail is meant for person-to-person email. Newsletters and bulk sends belong in Zoho Campaigns or a similar tool, on a separate subdomain if possible, so your main mailbox reputation stays clean.

Content matters too. Many links, shortened URLs, large images with little text and attachments from unknown senders all raise flags. Ask a few Gmail recipients to mark your mail as not spam and reply, which helps over time. Check Google Postmaster Tools for your domain's reputation.
