Definition
Email deliverability refers to the success rate of your emails reaching recipients' inboxes rather than being filtered to spam or rejected entirely. It's different from delivery rate (whether the email was accepted by the server). Key factors affecting deliverability include sender reputation, email authentication (SPF, DKIM, DMARC), list quality, engagement rates, and content. Industry average deliverability is around 85%, while top performers achieve 95%+.
