Deliverability
Deliverability
The ability of an email to reach the recipient's inbox rather than being blocked or filtered to spam.
Definition
Email deliverability refers to the ability of an email to successfully reach the recipient's inbox (not spam or promotions folders). It's influenced by multiple factors including sender reputation, authentication (SPF, DKIM, DMARC), list quality, engagement rates, content, and infrastructure. Good deliverability requires ongoing monitoring and optimization across all these areas.
Pro Tip
Deliverability is not binary - focus on inbox placement rate, not just whether emails are "delivered" to any folder.
