Email Deliverability
The likelihood of an email reaching the recipient's primary inbox rather than spam.
Full definition
Deliverability is determined by domain reputation, sender authentication (SPF, DKIM, DMARC), list quality, content quality, and engagement signals. Cold email deliverability is particularly tricky because senders lack prior engagement history with recipients. Practices like inbox warmup, list verification, and volume throttling are essential for maintaining deliverability at scale.
