Email deliverability in Zoho Campaigns refers to the proportion of emails that successfully land in the recipient’s inbox (rather than their spam folder or being rejected entirely). High deliverability is fundamental to email marketing effectiveness — a campaign to 10,000 subscribers that hits spam for 40% of them reaches only 6,000 people.
Key factors include sender domain authentication (SPF, DKIM, DMARC), sender reputation (complaint rate, bounce rate, engagement history), IP reputation, list quality (proportion of valid, engaged addresses), content quality (spam trigger words, image-to-text ratio), and volume consistency (sudden high-volume sends from a new IP harm reputation).
Track deliverability indicators in Zoho Campaigns: bounce rate (aim below 2%), spam complaint rate (aim below 0.1%), and unsubscribe rate. Monitor inbox placement using seed list tests if you send at high volume. Act quickly when metrics degrade.
