Deliverability
An email's ability to reach the inbox rather than spam or a rejection.
Deliverability depends on the reputation of the sending domain and IP, authentication (SPF, DKIM, DMARC), list quality and content. A list full of invalid addresses drops reputation and pushes even good emails to spam.
It is an asset that builds slowly and breaks fast. Systematic address verification and a controlled sending pace are the two main levers to preserve it.
