Spam score in Zoho Campaigns is a pre-send diagnostic that analyses your email content and flags elements that might cause spam filters to block or quarantine it. Common triggers include certain words in the subject line (Free, Guarantee, Act Now), poor image-to-text ratio, missing unsubscribe link, and missing physical address.
Run the spam checker in Zoho Campaigns before sending any campaign. The tool provides a score (lower is better) and a list of specific issues to fix. Address all high-impact warnings before sending, particularly technical issues like missing authentication records.
A low spam score improves your chances of inbox placement but does not guarantee it. Sender reputation, engagement history, and recipient-side spam filters all play additional roles. Spam score is a necessary check, not a sufficient guarantee of deliverability.
